Koch Institute for Integrative Cancer Research, in collaboration with scientists at the Harvard Stem Cell Institute and several other institutions, have developed an implantable device that in mice shielded insulin-producing beta cells from immune system attack for six months — a substantial proportion of life span.
Scientists identify a molecular key that helps cells maintain identity and prevents the conversion of adult cells into induced pluripotent stem cells — a process that would require a cell to “forget” its identity before assuming a new one.
Harvard Stem Cell Institute researchers have shown that the networks of communication among reprogrammed neurons and their neighbors in the brains of living animals can also be changed, or “rewired.”
Researchers create complex kidney structures from human stem cells derived from the skin of adult patients.
Harvard researchers report that by identifying and mimicking important developmental cues, they have been able to drive cells to grow into muscle fibers capable of contracting in a dish and multiplying in large numbers. This new method of producing muscle cells could offer a better model for studying muscle diseases, such as muscular dystrophy, and for testing potential treatments.
