Brain and spinal cord comprise more than just nerve cells. The extracellular matrix, a complex scaffold of proteins with sugar residues, surrounds the cells and influences their well-being. Prof. Wiese’s team is interested in the interaction of …
LA JOLLA, CA–Among stem cell biologists there are few better-known proteins than nestin, whose very presence in an immature cell identifies it as a “stem cell,” such as a neural stem cell. As helpful as this is to researchers, until now no…
In regenerative medicine, large supplies of safe and reliable human embryonic stem (hES) cells are needed for implantation into patients, but the field has faced challenges in developing cultures that can consistently grow and maintain clinical-grad…
Through a complex analysis of protein interactions, researchers from IRB Barcelona and the Joint Programme IRB-BSC have discovered new molecular mechanisms that may be involved in the development of Alzheimer’s disease. The study, a collaboration be…
Research conducted at Ohio State University suggests that cell biologists may be exposing the cell cultures they study to too much oxygen. This finding could have broad implications for cellular biology research, which receives billions of dollars of funding nationally, said Ohio State scientist Chandan Sen. He is the lead author of a study which suggests that cells act differently depending on how much oxygen they are exposed to, especially when it is too much.
