How Irv Weissman learned to figure things out
Irving Weissman had an unconventional start in science. The son of a hardware store operator and grandson of a fur trader, he learned lifelong lessons in research at the McLaughlin Research Institute in Montana.
Expert in cancer immunotherapy joins Stanford Medicine faculty
Crystal Mackall will lead the university’s efforts to translate basic science discoveries into immune-based treatments for pediatric and adult cancers.
Researchers urge lifting of NIH funding restrictions on chimeric research
In September, the National Institutes of Health halted research funding for chimeric human/nonhuman embryos until new funding guidelines are established. Stanford researchers describe the detrimental impact of a ban.
Precursor cells discovered that could help regrow heart arteries
Researchers discovered, in mice, the direct progenitors to coronary artery smooth muscle cells, the important component that encases the artery and gives it strength.
Sleep deprivation affects stem cells, reducing transplant efficiency
Although the research was done in mice, the findings have possible implications for bone marrow transplants, more properly called hematopoietic stem cell transplants, in humans.
Elusive liver stem cell identified in mice by researchers
Researchers have found a previously unknown population of cells in mice that function as liver stem cells. The finding could aid drug testing and increase understanding of liver biology and disease.
Gene discoveries may lead to regeneration of cells needed for hearing
The researchers identified patterns of gene expression that may determine whether the ear’s inner pillar cells can give rise to new hair cells, which are key to hearing.
Ulcer-causing bacteria induces stomach stem cell growth in mice, researchers find
The findings could explain why H. pylori is a risk factor for gastric cancer, the researchers said.
Scientists find way to monitor progress of stem cells after transplantation into brain
The ability to detect successful engraftment, integration and function of human cells implanted into the brain of a living animal could potentially speed stem-cell therapies’ path to clinical use.
Cell type responsible for scarring, skin-cancer growth identified
A single cell type in the skin of mice is a major contributor to scarring after wound healing or radiation damage, and facilitates the growth of melanoma. Blocking the cell’s activity in humans may be possible with currently approved drugs.
