More South Floridians Trying “Stem Cell Makeover”

Posted: July 21, 2012 at 10:11 am

Its fairly widely known that stem cells can mean life-saving treatments for deadly diseases.

Now, they are being used in the fight against wrinkles and more and more South Floridians are turning to the stem cell makeover.

Donna Pritchit is one of them. The 64-year-old headed into the operating room recently, wanting to turn back the hands of time without it being totally obvious.

I dont want someone to stop and go by and say Oh, she had a facelift. I want to have someone say Donna went on vacation she must be having a great life, she said before the $5,000 procedure began.

Dr. Sharon McQuillan at the Ageless Institute in Aventura marked the areas where she would take fat out of Pritchits belly and place it back into her face.

The retired teacher also hoped it would be her last step in getting rid of embarrassing acne scars.

I never wanted to go out in daylight and have anyone see me, she said.

The outpatient procedure began with traditional liposuction, and then McQuillan and her team processed that fat and concentrated the stem cells so they could be injected into Pritchits wrinkles and in places where she has lost fullness.

Well, stem cells in general are the cells in your body that regenerate tissue and heal tissue, and they make the skin look beautiful and younger, McQuillan explained. And they also the fat to remain alive so that the volume that we create stays, which has been a problem with fat transfer in the past.

Sweat glands grown from newly identified stem cells

Posted: July 21, 2012 at 10:11 am

ScienceDaily (July 20, 2012) To date, few fundamentals have been known about the most common gland in the body, the sweat glands that are essential to controlling body temperature, allowing humans to live in the worlds diverse climates. Now, in a tour de force, researchers at The Rockefeller University and the Howard Hughes Medical Institute have identified, in mice, the stem cell from which sweat glands initially develop as well as stem cells that regenerate adult sweat glands.

In their study, published in Cell, the scientists devised a strategy to purify and molecularly characterize the different kinds of stem cell populations that make up the complex sweat duct and glands of the skin. With this information in hand, they studied how these different populations of stem cells respond to normal tissue homeostasis and to different types of skin injuries, and how the sweat glands differ from their close cousins, the mammary glands.

No sweat. Researchers in Elaine Fuchs's lab identified four different types of paw-skin progenitor cells that are responsible for homeostasis and wound repair. This image shows that the sweat ductal and epidermal progenitors (in red) proliferate and repair an epidermal scratch wound; the sweat gland progenitors (in blue and green) show no signs of proliferation to this type of wound, but instead respond to deep glandular wounds. Mammary gland stem cells respond to hormonal induction by greatly expanding glandular tissue to increase milk production, explains Elaine Fuchs, Rebecca C. Lancefield Professor at Rockefeller and an investigator at the Howard Hughes Medical Institute. In contrast, during a marathon race, sweat gland stem cells remain largely dormant, and glandular output rather than tissue expansion accounts for the 3 liters of sweat our body needs. These fascinating differences in stem cell activity and tissue production are likely at the root why breast cancers are so frequent, while sweat gland cancers are rare. Their findings might also help in the future to improve treatments for burn patients and to develop topical treatments for people who sweat too much, or too little.

For now, the study represents a baby step towards these clinical goals, but a giant leap forward in our understanding of sweat glands, says the studys lead author, Catherine P. Lu, a postdoctoral researcher in Fuchss Laboratory of Mammalian Cell Biology and Development.

Each human has millions of sweat glands but they have rarely been extensively studied possibly due to the difficulty of gathering enough of the tiny organs to research in a lab, says Lu. The mouse is traditionally used as a model for human sweat gland studies, so in this project, Lu and colleagues laboriously extracted sweat glands from the tiny paw pads of mice the only place they are found in these and most other mammals.

The research team sought to discover whether the different cells that make up the sweat gland and duct contained stem (progenitor) cells, which can help repair damaged adult glands. We didnt know if sweat stem cells exist at all, and if they do, where they are and how they behave, she says. The last major studies on proliferative potential within sweat glands and sweat ducts were conducted in the early 1950s before modern biomedical techniques were used to understand fundamental bioscience.

Fuchs team determined that just before birth, the nascent sweat duct forms as a downgrowth from progenitor cells in the epidermis, the same master cells that at different body sites give rise to mammary glands, hair follicles and many other epithelial appendages. As each duct grows deeper into the skin, a sweat gland emerges from its base.

Lu then led the effort to look for stem cells in the adult sweat gland. The gland is made up of two layers -- an inner layer of luminal cells that produce the sweat and an outer layer of myoepithelial cells that squeeze the duct to discharge the sweat.

Lu devised a strategy to fluorescently tag and sort the different populations of ductal and glandular cells. The Fuchs team then injected each population of purified cells into different body areas of female host recipient mice to see what the cells would do.

Interestingly, when introduced into the mammary fat pads, the sweat gland myoepithelial cells generated fluorescent sweat gland-like structures. Each fluorescent gland had the proper polarized distribution of myoepithelial and luminal cells, and they also produced sodium potassium channel proteins that are normally expressed in adult sweat glands but not mammary glands, Lu says.

The study, published in the journal Stem Cell, adds to our understanding of the role of stem and next stage progenitor cells in tissue regeneration and in the diagnosis and treatment of cancer.

While stem cells are known to reside in organs such as the liver and pancreas, they are difficult to isolate. The new findings show that an antibody developed by the team can be used to capture the stem cells.

Professor Pera, program leader for Stem Cells Australia and Chair of Stem Cell Sciences at the University of Melbourne, said the antibody was able to detect progenitor cells in disease states such as cirrhosis of the liver, and in cancers such as pancreatic adenocarcinoma and oesophageal carcinoma.

"By being able to identify these cells, we hope to be able to learn more about their role in tissue regeneration and in cancer especially in the diagnosis and treatment of pancreatic cancer," he said.

"Cancers of the liver, pancreas and oesophagus are often very difficult to detect and challenging to treat."

The large collaboration of scientists from around the world working on this study evolved over many years with research undertaken in Professor Pera's laboratories at the then Australian Stem Cell Centre and at the University of Southern California.

Professor Pera and one of the co-authors on the paper, Dr Kouichi Hasegawa, were recently awarded an Australia-India Strategic Research Fund grant to continue their search for novel markers for liver, pancreatic and gut stem cells. Dr Hasegawa, who recently undertook a three month sabbatical at Stem Cells Australia, holds positions at Kyoto University's Institute for Integrated Cell-Materials Sciences and at the Institute for Stem Cell Biology and Regenerative Medicine at the National Centre for Biological Sciences in Bangalore, India.

"This funding will support us to develop more antibodies that can be used to assist in the identification and prospective isolation of stem and progenitor cells in these tissues and lead to the development of novel diagnostic and therapeutic reagents." Said Professor Pera.

One step closer to growing a tooth

Posted: July 20, 2012 at 11:10 pm

ScienceDaily (July 18, 2012) To build a tooth, a detailed recipe to instruct cells to differentiate towards proper lineages and form dental cells is needed. Researchers in the group of Professor Irma Thesleff at the Institute of Biotechnology in Helsinki, Finland have now found a marker for dental stem cells. They showed that the transcription factor Sox2 is specifically expressed in stem cells of the mouse front tooth.

Despite the development of new bioengineering protocols, building a tooth from stem cells remains a distant goal. Demand for it exists as loss of teeth affects oral health, quality of life, as well as ones appearance. To build a tooth, a detailed recipe to instruct cells to differentiate towards proper lineages and form dental cells is needed. However, the study of stem cells requires their isolation and a lack of a specific marker has hindered studies so far.

Researchers in the group of Professor Irma Thesleff at the Institute of Biotechnology in Helsinki, Finland have now found a marker for dental stem cells. They showed that the transcription factor Sox2 is specifically expressed in stem cells of the mouse incisor (front tooth). The mouse incisor grows continuously throughout life and this growth is fueled by stem cells located at the base of the tooth. These cells offer an excellent model to study dental stem cells.

The researchers developed a method to record the division, movement, and specification of these cells. By tracing the descendants of genetically labeled cells, they also showed that Sox2 positive stem cells give rise to enamel-forming ameloblasts as well as other cell lineages of the tooth.

Although human teeth dont grow continuously, the mechanisms that control and regulate their growth are similar as in mouse teeth. Therefore, the discovery of Sox2 as a marker for dental stem cells is an important step toward developing a complete bioengineered tooth. In the future, it may be possible to grow new teeth from stem cells to replace lost ones, says researcher Emma Juuri, a co-author of the study.

Inflammatory pathway spurs cancer stem cells to resist HER2-targeted breast cancer treatment

Posted: July 19, 2012 at 5:12 pm

Public release date: 19-Jul-2012 [ | E-mail | Share ]

Contact: Nicole Fawcett nfawcett@umich.edu 734-764-2220 University of Michigan Health System

ANN ARBOR, Mich. Breast cancer treatments such as Herceptin that target a marker called HER2 have dramatically improved outcomes for women with this type of cancer. But nearly half of these cancers are resistant to Herceptin from the start and almost all of them will eventually become resistant.

Now, researchers at the University of Michigan Comprehensive Cancer Center have discovered one reason why the cancer cells become resistant: They turn on a completely different pathway, one that is involved in inflammation, fueling the cancer independently of HER2.

The pathway at work involves a protein called Interleukin-6, or IL-6. The researchers also showed in mice that a drug that blocks IL-6 can stop this effect and overcome the Herceptin resistance.

"Resistance to HER2-targeted therapies remains a major challenge in treating breast cancer. Our study suggests that an IL-6 inhibitor in combination with Herceptin may be a valuable addition for treating HER2-positive breast cancer," says senior study author Max S. Wicha, M.D., Distinguished Professor of Oncology and director of the U-M Comprehensive Cancer Center.

Results of the study will be published in the Aug. 24 issue of Molecular Cell.

Not only are these cells resistant to Herceptin, but they develop higher proportions of cancer stem cells, the small number of cells within a tumor that fuel the growth and spread. This makes the tumor extremely aggressive and likely to spread throughout the body. The IL-6 inhibitor also was shown to prevent this increase in cancer stem cells.

"There is evidence that patients with a lot of IL-6 tend to do poorly. What we found now is that in many of the Herceptin-resistant breast cancers, the IL-6 inflammation loop is driving the cancer stem cell," says lead study author Hasan Korkaya, D.V.M., Ph.D., research assistant professor of internal medicine at the U-M Medical School.

The researchers found that blocking the IL-6 inflammatory loop almost completely blocked the cancer and the stem cells. Mice treated with the IL-6 blocker along with Herceptin immediately after the cancer developed never became resistant to Herceptin.

The Yin and Yang of Stem Cell Quiescence and Proliferation

Posted: July 19, 2012 at 5:12 pm

Newswise KANSAS CITY, MO Not all adult stem cells are created equal. Some are busy regenerating worn out or damaged tissues, while their quieter brethren serve as a strategic back-up crew that only steps in when demand shoots up. Now, researchers at the Stowers Institute for Medical Research have identified an important molecular cue that keeps quiescent mouse hematopoietic (or blood-forming) stem cells from proliferating when their services are not needed.

Publishing in the July 20, 2012 issue of Cell, the team led by Stowers Investigator Linheng Li, Ph.D., report that Flamingo and Frizzled 8, a tag team best known for its role in establishing cell polarity, are crucial for maintaining a quiescent reserve pool of hematopoietic stem cells in mouse bone marrow. Their finding adds new insight into the mechanism that controls the delicate balance between long-term maintenance of stem cells and the requirements of ongoing tissue maintenance and regeneration.

Hematopoietic stem cells daily produce billions of blood cells via a strict hierarchy of lineage-specific progenitors, says Li. Identifying the molecular signals that allow hematopoietic stem cell populations to sustain this level of output over a lifetime is fundamental to understanding the development of different cell types, the nature of tumor formation, and the aging process. My hope is that these insights will help scientists make meaningful progress towards new therapies for diseases of the blood.

The current working model, which grew out of earlier work by Li and others, postulates that hematopoietic stem cells (HSC), which are part of the reserve pool sit quietly and only divide a few times a year. They jump into action only when needed to replace active HSCs damaged by daily wear and tear or to increase their numbers in response to injury or disease. But how quiescent and active hematopoietic stem cell subpopulations are maintained and regulated in vivo is largely unknown.

What is known is that both populations of cells reside in adjacent specialized microenvironments, which provide many of the molecular cues that guide stem cell activity. Frequently cycling HSCs constitute around 90 percent of all hematopoietic stem cells and are found in the central marrow, where they seek the company of endothelial and perivascular cells. The main home base of quiescent hematopoietic stem cells is trabecular bone, the spongy part typically found at the end of long bones. Here, these cells engage in a constant molecular dialog with preosteoblasts, the precursors of bone-forming osteoblasts, which are characterized by the expression of N-cadherin.

Trying to decode the nature of the conversation graduate student and first author Ryohichi Sugimura focused on Flamingo (Fmi), a surface-based adhesion molecule, and Frizzled 8 (Fz8), a membrane-based receptor. Both molecules are part of the non-canonical arm of the so-called Wnt signaling pathway, a large network of secreted signaling molecules and their receptors. The canonical arm of the Wnt-signaling pathway exerts its influence through beta-catenin and helps regulate stem cell self-renewal in the intestine and hair follicles.

After in vitro experiments had revealed that Fmi and Fz8 accumulate at the interface between co-cultured quiescent hematopoietic stem cells and preosteoblasts, Sugimura and his colleagues were able to show that Fmi also regulates Fz8 distribution in vivo. This observation provided the first hint that these cooperation partners may carry at least part of the conversation that instructs hematopoietic stem cells to sit still. It also confirmed the previous finding by Lis team that a portion of HSCs resides in the N-cadherin+ osteoblastic niche.

When Sugimura examined the expression patterns of individual members of the Wnt signaling network within quiescent HSCs microenvironment he found that levels of canonical Wnt ligands where low. Levels of non-canonical Wnt ligands and inhibitors of the canonical arm of the Wnt signaling network, on the other hand, were high.

These observations indicated that the osteoblast niche provides a microenvironment in which non-canonical Wnt signaling prevails over canonical Wnt-signaling under normal conditions, says Sugimura. It also suggested that Fmi and Fz8 may play a direct role in maintaining the pool of quiescent hematopoietic stem cells.

Mice that had been genetically engineered to lack either Fmi or Fz8 provided the crucial clue: Not only had the number of quiescent hematopoietic stem cells plummeted in these mice, their hematopoietic stem cell function was reduced by more than 70 percent as well.

Mechanisms that allow embryonic stem cells to become any cell in the human body identified

Posted: July 18, 2012 at 10:10 pm

ScienceDaily (July 18, 2012) New research at the Hebrew University of Jerusalem sheds light on pluripotency -- the ability of embryonic stem cells to renew themselves indefinitely and to differentiate into all types of mature cells. Solving this problem, which is a major challenge in modern biology, could expedite the use of embryonic stem cells in cell therapy and regenerative medicine.

If scientists can replicate the mechanisms that make pluripotency possible, they could create cells in the laboratory which could be implanted in humans to cure diseases characterized by cell death, such as Alzheimer's, Parkinson's, diabetes and other degenerative diseases.

To shed light on these processes, researchers in the lab of Dr. Eran Meshorer, in the Department of Genetics at the Hebrew University's Alexander Silberman Institute of Life Sciences, are combining molecular, microscopic and genomic approaches. Meshorer's team is focusing on epigenetic pathways -- which cause biological changes without a corresponding change in the DNA sequence -- that are specific to embryonic stem cells.

The molecular basis for epigenetic mechanisms is chromatin, which is comprised of a cell's DNA and structural and regulatory proteins. In groundbreaking research performed by Shai Melcer, a PhD student in the Meshorer lab, the mechanisms which support an "open" chromatin conformation in embryonic stem cells were examined. The researchers found that chromatin is less condensed in embryonic stem cells, allowing them the flexibility or "functional plasticity" to turn into any kind of cell.

A distinct pattern of chemical modifications of chromatin structural proteins (referred to as the acetylation and methylation of histones) enables a looser chromatin configuration in embryonic stem cells. During the early stages of differentiation, this pattern changes to facilitate chromatin compaction.

But even more interestingly, the authors found that a nuclear lamina protein, lamin A, is also a part of the secret. In all differentiated cell types, lamin A binds compacted domains of chromatin and anchors them to the cell's nuclear envelope. Lamin A is absent from embryonic stem cells and this may enable the freer, more dynamic chromatin state in the cell nucleus. The authors believe that chromatin plasticity is tantamount to functional plasticity since chromatin is made up of DNA that includes all genes and codes for all proteins in any living cell. Understanding the mechanisms that regulate chromatin function will enable intelligent manipulations of embryonic stem cells in the future.

"If we can apply this new understanding about the mechanisms that give embryonic stem cells their plasticity, then we can increase or decrease the dynamics of the proteins that bind DNA and thereby increase or decrease the cells' differentiation potential," concludes Dr. Meshorer. "This could expedite the use of embryonic stem cells in cell therapy and regenerative medicine, by enabling the creation of cells in the laboratory which could be implanted in humans to cure diseases characterized by cell death, such as Alzheimer's, Parkinson's, diabetes and other degenerative diseases."
