There were reports that the some of the stem cell lines were tainted with mouse cells. Other reports indicated that some of the libnes were immature and not yet stable or useable. The controversy is not likely to ease any time soon. How Brain Cells Remember Their Birth Order While teasing out the molecular signals that govern neural development in fruit flies, researchers have discovered how brain cells remember the order in which they are born from precursor stem cells. This type of molecular memory appears to determine the specific cell type the newly born cells will become and influences where in the developing brain those cells will reside permanently.
Transcription factors are proteins that activate or repress the expression of genes.
Four days after the heart attack, the physicians took bone marrow from the patient. Stem cells from the bone marrow were injected into the affected artery and eventually reached the heart muscle.
