Growth regulation of the interstitial cell population in hydra. III. Interstitial cell density does not control stem cell proliferation.


The interstitial cells of hydra contain a stem cell population which produces several classes of differentiated cell types. A model has been proposed which governs the growth rate of the interstitial cell population. This model, based on the density of interstitial cells in the tissue, makes specific predictions about the relationships among this density… (More)
