Boston Stem Cell Biotech Start-up Asymmetrex Will Present Essential Technologies for Stem Cell Medical Engineering at …

Posted: March 18, 2015 at 8:51 pm

Boston, MA (PRWEB) March 18, 2015

In the vast flow of new scientific research, discoveries, and information, it is not uncommon for important scientific advances to go unappreciated, or even just unnoticed, for surprisingly long periods of time. The Boston stem cell medicine technology start-up company, Asymmetrex is working to make sure that its growing portfolio of adult tissue stem cell technology patents obtains wide notice, appreciation, and investment.

In late 2014, the company started a digital media campaign to achieve greater visibility for its patented technologies that address the major barriers to greater progress in stem cell medicine. These include technologies for identifying, counting, and mass-producing adult tissue stem cells. The two presentations scheduled for the 5th World Congress on Cell and Stem Cell Research in Chicago continue Asymmetrexs efforts to better inform medical, research, and industrial communities focused on advancing stem cell medicine of the companys vision for implementation of its unique technologies.

Asymmetrex holds patents for the only method described for routine production of natural human tissue stem cells that retain their normal function. The company also holds patents for biomarkers that can be used to count tissue stem cells for the first time. The companys most recently developed technology was invented with computer-simulation leader, AlphaSTAR Corporation. In partnership, the two companies created a first-of-its-kind method for monitoring adult tissue stem cell number and function for any human tissue that can be cultured. This advance is the basis for the two companies AlphaSTEM technology for detecting adult tissue stem cell-toxic drug candidates before conventional preclinical testing in animals or clinical trials. Asymmetrex and AlphaSTAR plan to market the new technology to pharmaceutical companies. The implementation of AlphaSTEM technology would accelerate drug development and reduce adverse drug events for volunteers and patients. At full capacity use, AlphaSTEM could reduce U.S. drug development costs by $4-5 billion each year.

Cancer stem cells are resistant to chemotherapy and consequently tend to remain in the body even after a course of treatment has finished, where they can often trigger cancer recurrence or metastasis. A new study by researchers from the A*STAR Institute of Bioengineering and Nanotechnology has found that using nanoparticles to deliver an anti-cancer drug that simultaneously kills cancer cells and cancer stem cells significantly reduces the recurrence and metastasis of lung cancer.

The drug phenformin is very effective against cancer stem cells. It is related to the popular anti-diabetic drug metformin but is 50 times more potent against cancer cell lines. However, phenformin is too toxic in its free form to be administered to patients at the doses required to kill both normal cancer cells and cancer stem cells. Now, Yi Yan Yang and her colleagues at the Institute of Bioengineering and Nanotechnology in Singapore have found a way to overcome this problemusing self-assembling polymer nanoparticles to deliver the drug.

In the first study to use polymer nanoparticles to deliver phenformin to target both cancer cells and cancer stem cells, Yang and co-workers found that phenformin-loaded nanoparticles targeted both kinds of cancer cells in a mouse model of human lung cancer.

The nanoparticles released the drug in a sustained manner due to their hydrophilic shells, which "prevent enzymatic degradation of the cargo and protein adsorption onto the nanoparticles," explains Yang. "This also prolongs blood circulation so that the cargo-loaded nanoparticles have enough time to accumulate in tumor tissues."

This delivery method enabled Yang and her team to arrest the growth of cancer and cancer stem cells when the nanoparticles were delivered to implanted human lung cancer in mice.

"The results showed that the phenformin-loaded nanoparticles were more effective than free phenformin in inhibiting the growth of both cancer stem cells and normal cancer cells," Yang says. Moreover, the nanoparticles did not induce the liver toxicity observed in systemically administered phenformin.

The method can also be extended to other drugs. The team has used the nanoparticle-based delivery system in a mouse model of human breast cancer to deliver the anti-cancer drug, doxorubicinanother drug that is toxic at certain doses but is capable of killing cancer stem cells. "The combination shrank tumors by more than 40 per cent and was more effective than treatment with either drug alone," says Yang.

The team is now seeking to collaborate with pharmaceutical companies to bring this technology to human clinical trials.

Saudi student takes initiative for stem cells donation in Canada

Posted: March 18, 2015 at 8:50 pm

A Saudi scholarship student has recently launched a humanitarian initiative in Halifax, Canada, for donation of stem cells to minority groups, sabq.com online paper has reported. Dr. Mohammad Al-Mohammadi, who was sent by the National Guard to Canada to conduct advanced studies in blood diseases and the implantation of stem cells, said that many of those who are infected with blood diseases may need stem cell implants, but find this difficult as they do not belong to European origins and therefore may not find donors that match their needs. The Saudi researcher attributed this problem to the poor representation of this minority category of people (non-Europeans) at the national registry of donors in Canada, as well as internationally. He said that most of donor registries were concentrated in developed countries where non-European minorities live and work and, accordingly, their representation in the organ donor registries becomes less frequent. Based on the above, Al-Mohammadi launched his campaign by forming a team from a group of scholarship students of various medical, engineering and administrative areas. The team intends to provide a good image of Islamic and Saudi culture, and want to stress the importance of stem cell donation and correct a lot of misconceptions in this regard. Al-Mohammadi also established web pages and forums that focus on the issue under the supervision of the Canadian organizations concerned with the registration of donors. The campaign reportedly drew a high turnout from the Canadian community, including both Muslims and non-Muslim of different ethnicities. Nagwa Mousa, a medical expert, said this initiative comes as proof of the creativity and intelligence of islamic thinking, hoping that one day the initiative will be applied all across the Arab world.

The human gut is a remarkable thing. Every week the intestines regenerate a new lining, sloughing off the equivalent surface area of a studio apartment and refurbishing it with new cells. For decades, researchers have known that the party responsible for this extreme makeover were intestinal stem cells, but it wasnt until this year that Scott Magness, PhD, associate professor of medicine, cell biology and physiology, and biomedical engineering, figured out a way to isolate and grow thousands of these elusive cells in the laboratory at one time. This high throughput technological advance now promises to give scientists the ability to study stem cell biology and explore the origins of inflammatory bowel disease, intestinal cancers, and other gastrointestinal disorders.

But it didnt come easy.

One Step Forward . . .

When Magness and his team first began working with intestinal stem cells some years ago, they quickly found themselves behind the eight ball. Their first technique involved using a specific molecule or marker on the surface of stem cells to make sure they could distinguish stem cells from other intestinal cells. Then Magnesss team would fish out only the stem cells from intestinal tissues and grow the cells in Petri dishes. But there was a problem. Even though all of the isolated cells had the same stem cell marker, only one out of every 100 could self-renew and differentiate into specialized cells like a typical stem cell should. (Stem cells spawn cells that have specialized functions necessary for any organ to work properly.)

The question was: why didnt the 99 others behave like stem cells? Magness said. We thought it was probably because theyre not all the same, just like everybody named Judy doesnt look the same. There are all kinds of differences, and weve been presuming that these cells are all the same based on this one name, this one molecular marker. Thats been a problem. But the only way to solve it so we could study these cells was to look at intestinal stem cells at the single cell level, which had never been done before.

Magness is among a growing contingent of researchers who recognize that many of the biological processes underlying health and disease are driven by a tiny fraction of the 37 trillion cells that make up the human body. Individual cells can replenish aging tissues, develop drug resistance, and become vehicles for viral infections. And yet the effects of these singular actors are often missed in biological studies that focus on pooled populations of thousands of seemingly identical cells.

Distinguishing between the true intestinal stem cells and their cellular look-a-likes would require isolating tens of thousands of stem cells and tracking the behavior of each individual cell over time. But Magness had no idea how to accomplish that feat. Enter Nancy Allbritton, PhD, chair of the UNC/NCSU Joint Department of Biomedical Engineering. The two professors met one day to discuss Magness joining the biomedical engineering department as an adjunct faculty member. And they did discuss it. And Magness did join. But the meeting quickly turned into collaboration. One of Allbrittons areas of expertise is microfabrication the ability to squeeze large devices into very small footprints. During their meeting, Allbritton showed Magness her latest creation, a device smaller than a credit card dotted with 15,000 tiny wells for culturing cells.

For decades, researchers have known that the party responsible for this extreme makeover were intestinal stem cells, but it wasn't until this year that Scott Magness, PhD, associate professor of medicine, cell biology and physiology, and biomedical engineering, figured out a way to isolate and grow thousands of these elusive cells in the laboratory at one time. This high throughput technological advance now promises to give scientists the ability to study stem cell biology and explore the origins of inflammatory bowel disease, intestinal cancers, and other gastrointestinal disorders.

"It was like a light bulb went off, and I realized I was looking at the answer to a billion of our problems," Magness said.

Micro Magic

Each microwell is as thick as a strand of hair. By placing individual stem cells into the microwells, Magness and postdoctoral fellow Adam Gracz, PhD, could watch the cells grow into fully developed tissue structures known as mini-guts. Each microwell could be stamped with a specific address, which would allow researchers to track stem cells that were behaving as expected and those that weren't.
