A Harvard-led team is the first to demonstrate the ability to use low-power light to trigger stem cells inside the body to regenerate tissue, an advance they reported in Science Translational Medicine. The research, led by David J. Mooney, Robert P. Pinkas Family Professor of Bioengineering at the Harvard School of Engineering and Applied Sciences (SEAS), lays the foundation for a host of clinical applications in restorative dentistry and regenerative medicine more broadly, such as wound healing, bone regeneration, and more.
The team used a low-power laser to trigger human dental stem cells to form dentin, the hard tissue that
BioTime Inc, a biotechnology company that develops and markets products in the field of regenerative medicine, and its subsidiaries OrthoCyte Corporation and LifeMap Sciences reported today a means of manufacturing seven distinct types of cartilage, bone, and tendon cells from human embryonic stem cells. The paper, scheduled to be published online (ahead of print) at 1600 GMT today in the peer-reviewed journal Regenerative Medicine, characterizes the seven cell types generated using BioTime’s proprietary PureStem(TM) technology. The study compared the novel cells with adult stem cells, known as mesenchymal stem cells (MSCs), and revealed properties of the new cell lines
Piece by missing piece, scientists at the Keck School of Medicine of USC are deciphering the powerful gene regulatory circuit that maintains and controls the potential of embryonic stem cells (ESCs) to form any type of cell in the body.
Recent findings by Provost Professor Andrew McMahon, director of the Eli and Edythe Broad Center for Regenerative Medicine and Stem Cell Research at USC, and Qilong Ying, associate professor of cell and neurobiology, underscore the essential role of basic science in paving the way for future medical breakthroughs.
McMahon and Ying are in pursuit of the ways in which the intricate
Stanford stem cell researcher Irving Weissman, MD, published an article in Cell Stem Cell today discussing barriers to stem cell research:
While I am usually an optimist, I must admit that there is a possibility that we will continue to be in the Dark Ages of medicine for quite some time. I fear that therapies using purified tissue and organ-specific stem cells – the only self-renewing cells in a tissue or that can regenerate that tissue or organ for life – will remain elusive.
Weissman, who directs Stanford’s Institute for Stem Cell Biology and Regenerative Medicine, goes on to cover the
With the motto Advancing Science to Heal the World the BU stem cell scientists who founded the Center for Regenerative Medicine(CReM) could be pegged as starry-eyed idealists or scientific superheroes. Or perhaps a bit of both.
CReM codirectors Darrell Kotton, Gustavo Mostoslavsky, and George Murphy have established themselves as venturesome researchers who are willing to share their discoveries with almost anyone. And they do it for free—bucking the prevailing trend to patent, publish, and protect scientific breakthroughs. The trio’s “open source biology” is just one of the things they teach to the next generation of stem cell researchers at CReM.
