Researchers at IRB Barcelona discover a new mechanism that regulates stem cell division
Stem cells have the extraordinary capacity to divide producing two very distinct cells: one retains stem cell identity and continues to undergo asymmetric division, while the other specializes for a specific function and shows limited capacity to divide. This strategy allows a single stem cell to generate great amounts of tissue during a lifetime. Researchers at IRB Barcelona, have discovered that one of the key factors in asymmetric stem cell division is the behavior of centrosome. (2007-03-05)
