Interactive niches
Article Abstract:
The niche that regulates blood-forming stem cells in adult animals has eluded researchers until now. The decisions of cell fate in the developing embryo are governed by a complex interplay between cell-autonomous signals and stimuli from the surrounding tissue, the microenvironment and the same process controls the birth and maturation of stem cells that replenish mature cell populations in adults.
