Cell kinetics in the mouse small intestine during immediate postnatal life

Abstract
The cell proliferation kinetics in the small intestine of newborn Balb/c mice were studied, from day 1 through to day 21 after birth. The size of the functional compartment and the proliferation compartment was determined as well as the cell production rate in the crypt using the micro-dissection technique combined with metaphase arrest method. The effect of weaning on cell proliferation was studied.
