How Stem Cells Know What to Become

How do stem cells know what type of cell they are supposed to become? Ph.D. student Jack Allen explains this and the research being done in the lab of Dr. Ricardo Zayas on tissue regeneration. Find out more here: http://www.bio.sdsu.edu/faculty/zayas/index.html

Stem Cell Therapy For Treating Pattern Baldness

RepliCel Life Sciences is developing an autologous cell-based procedure for the treatment of androgenetic alopecia (pattern baldness) and general hair loss in men and women. The procedure has the potential to become the first minimally invasive solution for hair loss. Please see website for more info.

Stem Cell Therapy for Arachnoiditis Helps a Tennessee Woman Walk Again

Chronic disease can present challenges for patients and their families on many levels, from the emotional to the physical. For many, the growing realization that there is no cure for their illness can lead to frustration at best as they learn to adapt their daily routine, quality of life and plans for the future to a new reality.

Such was the case for Dr. Sara Davis when her active life as a wife, mother and physician was turned on its head by arachnoiditis, a chronic pain disorder affecting the spinal nerves. Dr. Davis was eventually confined to a wheelchair and struggled daily with pain, lack of mobility and the inability to perform many menial tasks. As a physician, she continued to search for new avenues of treatment and held out hope that something would someday cure her condition or improve her symptoms. Stem cell therapy became that ray of hope in 2015 when her research led her to Dr. Todd Malan and his advanced use of stem cell therapies that were available worldwide, but not FDA approved in the U.S.

Mathematics of Stem Cells

Presented by the University of California Irvine School of Physical Sciences. Cell populations are complex. Their collective functioning, turnover, and cooperation are at the basis of the life of multicellular organisms, such as humans. When this goes wrong, an unwanted evolutionary process can begin that leads to cancer. Mathematics cannot cure cancer, but it can be used to understand some of its aspects, which is an essential step in winning the battle.

The Beauty Of Pluripotent Stem Cells – Great Intro

By Muhammad Khan, TEDxBrentwoodCollegeSchool

Stem cells are extremely new to science, and research (despite being hindered) is advancing at an amazing pace. In 2012 a man named Shinya Yamanaka made the ground breaking discovery of induced pluripotent stem cells – essentially a cell that is reprogrammed into thinking it is a stem cell and behaves exactly as a stem cell would. The technology and possibilities that Shinya Yamanaka unlocked with this discovery is mind boggling, the possibilities are endless especially because it removes the ethical debate of stem cells being potential children.

I am a 17 year old student at Brentwood, this is both my first and last year and I’m looking forward to an amazing one. I’ve always been interested in science, in particular the medical sciences have always fascinated me. Growing up I’d always look for new science news and through all of that I found the amazing science of stem cells. Since then, they have been a huge interest of mine, so much so that I voluntarily did an extended essay on it. Bringing that interest and fascination to people who might not be so interested in science is something that I am really looking forward to with this talk.

This talk was given at a TEDx event using the TED conference format but independently organized by a local community. Learn more at http://ted.com/tedx

Studying Stem Cells With Computational Image Analysis

Stem cell research is one of the most exciting and rapidly evolving fields in science today. Using the latest software developed at Drexel’s Computational Image Sequence Analysis Lab , scientist can now automatically track tens of thousands of time lapse images to better determine cell growth, movement, and proliferation (a process that used to take months of manual analysis to complete).

Engineering Stem Cells: From In Vitro to In Situ


Engineering Stem Cells: From In Vitro to In Situ

Stem cells are a valuable cell source for tissue engineering, disease modeling and drug screening. A recent discovery in stem cell biology is that differentiated cells can be reprogrammed into induced pluripotent stem cells (iPSCs) and desired cell types. Although the effects of transcriptional factors and chemical compounds have been widely studied, the role of biophysical factors on cell reprogramming is not clear. Dr. Li will present his findings on how biophysical factors can regulate the epigenetic state and thus the cell memory and reprogramming process, which has important implications in cell conversion into iPSCs and specific cell types. To illustrate the important role played by stem cells in tissue regeneration and remodeling in vivo, Dr. Li will use blood vessel regeneration as an example to demonstrate an evolution from in vitro tissue engineering to in situ tissue engineering approach. In this approach, endogenous stem cells are recruited by the use of bioactive scaffolds to promote tissue regeneration. In addition, endogenous stem cells are also involved in the regeneration of microvessels and the development of vascular diseases, suggesting a general role of stem cells in vascular remodeling.

Utilizing Oral Mucosa Stem Cells for the Prevention and Treatment of Ischemic Heart Failure

Advancing Toward Multiple Sclerosis Therapies Using Stem Cells

Dr. Tom Lane of the University of Utah (formerly a CIRM grantee at UC – Irvine) describes his lab’s experimental results that show a dramatic reversal in the debilitating effects of a multiple sclerosis (MS)-like illness in mice after treating them with human neural stem cells. After just two weeks, the mice—who had previously been unable to walk or even feed themselves—had regained basic motor skills. And six months later the improvements have only continued.
