Stem Cell Therapy May Provide Hope for Hair Loss

New research published in the journal Proceedings of the National Academy of Sciences shows key molecular events that occur with hair growth in mice. A team of scientists from the University of Southern California in Los Angeles transplanted a special type of cell, called progenitor cells, into hairless mice and then observed how the cells reacted. They discovered that hair …

Patching Up a Broken Heart with Stem Cells

A new study shows tremendous promise for patients suffering from heart failure. The study was conducted on 27 patients whose heart failure therapy had still not resolved their symptoms and extracted their own stem cells from the thigh muscle of each patient. The extracted stem cells were then formed into a sheet and placed on each patient’s heart. Researchers then …

FDA Regulation of Stem Cells

FDA regulates stem cells in the U.S. to ensure that they are safe and effective for their intended use. “Stem cells can come from many different sources and under the right conditions can give rise to many different cell types,” says Stephanie Simek, Ph.D., deputy director of FDA’s Office of Cellular, Tissue and Gene Therapies. But there are many other …

Scientists reprogram embryonic stem cells to expand their potential cell fates

Researchers from the University of California, Berkeley, have found a way to reprogram mouse embryonic stem cells so that they exhibit developmental characteristics resembling those of fertilized eggs, or zygotes. These “totipotent-like” stem cells are able to generate not only all cell types within a developing embryo, but also cell types that facilitate nutrient exchange between the embryo and the …

How the discovery of stem cells revolutionized medicine

Stemcell Technologies Inc. makes more than 1,500 types of tissue culture media, the crucial tools for harvesting and growing stem cells, and sells them to laboratories and hospitals in more than 70 countries around the world. As such, the Vancouver biotechnology company is one of the key players in the burgeoning field of regenerative medicine, a quiet behind-the-curtain player in …

Stem cells lay foundation for treatments of cancer, other disorders

Stem cell research is now considered among the most seminal medical findings of the past century, on a par with the discovery of the double-helical structure of DNA by James Watson and Francis Crick. Stem cells not only revolutionized the treatment of cancer, but laid the foundations for regenerative medicine, and fueled the emergence of a biomedical industry, particularly in …

The Stem-Cell Revolution Is Coming — Slowly

In 2001, President George W. Bush issued an executive order banning federal funding for new sources of stem cells developed from preimplantation human embryos. The action stalled research and discouraged scientists. Five years later, a Kyoto University scientist, Shinya Yamanaka, and his graduate student, Kazutoshi Takahashi, re-energized the field by devising a technique to “reprogram” any adult cell, such as …

Evidence for Cardiomyocyte Renewal in Humans

It has been difficult to establish whether we are limited to the heart muscle cells we are born with or if cardiomyocytes are generated also later in life. We have taken advantage of the integration of 14C, generated by nuclear bomb tests during the Cold War, into DNA to establish the age of cardiomyocytes in humans. We report that cardiomyocytes …

Stroke Survivor Walks Again After Doctors Inject Stem Cells Directly into Brain

A surgical procedure that involves drilling holes and injecting stem cells into stroke patients’ brains seems to have contributed to a wheelchair-bound stroke patient regaining the ability to walk. Despite the major recovery exhibited by patients, further study must be made to investigate the true impact. READ MORE
