Neural<unk> s (green) in olfactory bulb with astrocytes (blue). Example of the pattern of division of a<unk>  <unk>  which results in the production of an intermediate<unk>  (IPC). Both cells later produce one or two neural cells (N). A<unk>  is a biological cell that can differentiate into a specific cell type. Stem cells and<unk> s have this ability in common. However, stem cells are less specified than<unk> s.<unk> s can only differentiate into their "target" cell type. The most important difference between stem cells and<unk> s is that stem cells can replicate indefinitely, whereas<unk> s can divide only a limited number of times. Controversy about the exact definition remains and the concept is still evolving. The terms<unk> " and "stem cell" are sometimes equated.
