euronews hi-tech - The computer printer at the heart of the matter
http://www.euronews.com Scientists are taking the idea of 3D computer printing and catapulting it into the realms of something more suited to science fiction. The idea of printing a human heart, liver or kidney is becoming closer to reality every day. Several teams of researchers around the world are working on the process. And one company, Organovo from San Diego in California has taken on the challenge of using 3D printing technology to create human tissue. They work with one of the world #39;s first bio-printers. The NovoGen MMX is capable of reproducing human tissue in three dimensions. The idea is ultimately to print entire organs that can be transplanted. The company #39;s CEO, Keith Murphy, said: "It prints materials from two deposition heads, cells from one side and gel from the other, with plus or minus 20 microns precision. So you print cells and the cells join together in three dimensions to make one piece of tissue." Thirty or so engineers and biologists work on improving every aspect of the technique. They create what they call #39;bio-ink #39; from stem cells that have been grown on fatty tissue or bone marrow. They are further cultured in flasks, because the process needs several million of them to create just one millimetre of tissue. They print the cells and a fixing gel layer by layer to form a shape that is controlled by computer. After that nature takes over and the cells organise themselves into living tissue. In the lab they can print fragments of heart and lung tissue ...From:EuronewsViews:78 5ratingsTime:03:53More inShows

ll4.me The Tumor Microenvironment This book will explore the many biological and physical aspects of the tumor microenvironment. The book will include chapters on the various cells that influence tumor growth and function as well as the cell-associated and soluble proteins that can promote invasion and metastasis. Several chapters will describe endothelial cells and pericytes that form tumor vasculature. Insights on the role of progenitor and stem cells will be included. The contribution of the supporting stroma will be addressed in addition to cell-cell signaling and cell-matrix interactions. Additional chapters will describe the influence of infiltrating cells of the immune system on tumor growth.

Methods In Bioengineering: Stem Cell Bioengineering
ll4.me Methods In Bioengineering: Stem Cell Bioengineering In stem cell research there are several key methods that, once mastered, can be extremely powerful. These methods enable you to rigorously test hypotheses, compare results to "gold standards," and may even spur improvements to existing protocols. This book describes numerous methods to derive, manipulate, target, and prepare stem cells for clinical use. The methods described here help you derive and test human embryonic stem cells, analyze bone marrow stem cell function in vitro and in vivo, image a stem cell transplant, cryopreserve stem cells and differentiate stem cells using microscale techniques.

Public Service Announcement: Giuliana and Bill Rancic Save Cord Blood with Cord Blood Registry
Like any good parent, Giuliana and Bill Rancic wanted the best for their newborn. Thanks to Cord Blood Registry, planning for their son #39;s healthy future was possible even before he was born. The blood in a newborn #39;s umbilical cord contains young, pristine stem cells that are used to treat serious diseases like cancers and blood diseases. These powerful cells are also being studied in clinical trials for their ability to help treat conditions like cerebral palsy and autism. The Rancics know firsthand the importance of preparing for a healthy future. Their experience with infertility and an unexpected illness led them to do everything possible to protect their child #39;s health; including cord blood banking with CBR. It is so important that every parent become informed. That #39;s why Giuliana and Bill have teamed with Cord Blood Registry through the Healthy Futures Campaign -- to raise awareness about the value of cord blood and options for saving it.

New regenerative medicine helps people with diabetic retinopathy see again

Written by ALLEN GUAN Aggie Science Writer Published on November 14, 2012 Filed under Science & Technology

Blindness affects all demographics within the United States. While some cases occur at birth, other cases occur as a side effect of degenerative diseases.

One group of researchers from UC Santa Barbara believes there is a simple cure. The team has been analyzing and developing a use for embryonic stem cells in the treatment of damaged retinal cells. This new treatment could effectively help cure some forms of blindness due to degenerating retinas.

There are two main causes of the deterioration of retinal cells. One is age-related macular degeneration, and the second is due to diabetes. The first is natural, exclusively affecting the elderly, but the latter has become a bigger issue. According to the National Institutes of Health, diabetes is the leading cause of blindness in the U.S. In the past decade alone, there has been a 21-percent increase in the number of cases of type 2 diabetes. This brings us to a possible side effect of diabetes: diabetic retinopathy.

Diabetic retinopathy is a disease prevalent in young adults due to the increase in obesity rates. It causes the deterioration of retinal cells, [and] we hope the use of stem cells can help repair this degeneration, said Dennis Clegg, a leading researcher on the UCSB team studying stem cell development. We have some sort of timeframe for our project, but right now weve just begun to explore this field. Were reporting back to the FDA the research on stem cells with our initial studies, and hopefully well be able to explore deeper.

In a healthy person, the body is able to secrete enough insulin to help absorb glucose, the smallest biologically active sugar. A diabetic person, on the other hand, is unable to absorb glucose normally, which results in free-floating sugars in the bloodstream. This glucose builds up over the course of several years, damaging blood vessels throughout the body, leading to diabetic retinopathy and damage to the blood vessels in the eyes.

The damage inhibits blood flow to the rest of the retina, which depletes the retina of oxygen and vital nutrients. The damage can also cause blood to leak, create scar tissues or even create a detached retina. The only treatment available is to physically remove the damaged areas of the retinas using lasers, and as usual, there are risks and unwanted side effects that could permanently impair vision. This is where embryonic stem cells can help provide the key to repairing damaged retinas. By manipulating the stem cells to mimic retinal cells, doctors can inject the cells under the retina and start the repair process.

Although the UCSB research team is pursuing a relatively new form of regenerative medicine, there are already some applications of stem cells in use.

If you inject [stem cells] into a knee thats damaged, you can regenerate the cartilage. This is currently being done with horses at the vet school, said said Gerhard Bauer, an assistant professor at the UC Davis Institute for Regenerative Cures. So here at UC Davis, we treat horses with stem cells from fat or bone marrow stem cells, and inject them into the joints so they can walk again we can do very similar things in humans, so they have many many applications.
