Mutations in donors’ stem cells may cause problems for cancer patients
Posted by Nicholi Avery in categories: biotech/medical, genetics, health
A new study from Washington University School of Medicine in St. Louis suggests that bone marrow — or blood stem cells — from healthy donors can harbor extremely rare mutations that can cause health problems for the cancer patients who receive them.
A stem cell transplant — also called a bone marrow transplant — is a common treatment for blood cancers, such as acute myeloid leukemia (AML). Such treatment can cure blood cancers but also can lead to life-threatening complications, including heart problems and graft-versus-host disease, in which new immune cells from the donor attack a patient’s healthy tissues.
A new study from Washington University School of Medicine in St. Louis suggests that extremely rare, harmful genetic mutations present in healthy donors’ stem cells — though not causing health problems in the donors — may be passed on to cancer patients receiving stem cell transplants. The intense chemo- and radiation therapy prior to transplant and the immunosuppression given after allow cells with these rare mutations the opportunity to quickly replicate, potentially creating health problems for the patients who receive them, suggests the research, published Jan. 15 in the journal Science Translational Medicine.

Chip Walter, “Immortality, Inc”
Posted by John Davies in categories: biotech/medical, business, internet, life extension, Ray Kurzweil, robotics/AI
Chip Walter discusses his book, “Immortality, Inc”, at Politics and Prose.
Living forever has always been a dream, but with today’s science, technology, and visionary billionaires, it may be a distinct possibility. At the very least, as Walter reports in this compelling investigation, immortality researchers are changing the way we view aging and death. Looking at the science, business, and culture of this radical endeavor, Walter, a science journalist, author of Last Ape Standing, and former CNN bureau chief, lays out the latest research into stem cell rejuvenation, advanced genomics, and artificial intelligence; talks to key thinkers such as Ray Kurzweil and Aubrey de Grey; and takes us into the Silicon Valley labs of human genomics trailblazer Craig Venter and molecular biologist and Apple chairman Arthur Levinson. Walter is in conversation with Hilary Black, executive editor at National Geographic Books.

First heart surgery performed using iPS cells
Posted by Quinn Sena in category: biotech/medical
A Japanese group of researchers says it has conducted heart surgery using sheets of heart muscle cells made from iPS cells.
Induced pluripotent stem cells are created from reprogrammed human cells and can develop into various kinds of body tissue.
The Osaka University team, led by Professor Yoshiki Sawa, aims to establish a treatment for patients with serious heart disease by restoring the organ’s function. The team’s surgery involves putting sheets of heart muscle cells derived from iPS in a patient’s heart.
