## Abstract Neurons, neuroglia (astrocytes and oligodendrocytes), and ependymal cells are three distinct categories of neural cells in the central nervous system. In the mature brain and spinal cord, the classical histological criteria define these cells by their microscopic structure very well. Du

Among highly proliferating tissues the intestinal tissue is of particular interest. Techniques are available that permit an insight into how intestinal crypts as the basic macroscopic tissue unit are regenerated from a small population of self-maintaining stem cells. However, neither the precise num
## Abstract In the mouse jejunum, as in the rat, a new steady state was established 3 weeks after resection of 30% of the small intestine. The mean height of a villus, crypt, and proliferative zone increased. We studied the effects of this new steady state on the distribution of the four main epith
A generally accepted model for the origin of human cancer is that tumours arising from the gut-lining epithelium-the adenomas and carcinomas-are of clonal origin, i.e., they are derived from a single 'abnormal' cell. Recent work has shed considerable light on these matters and suggests that this mod
