Study of biological rhythms of small intestinal cryptic epithelial mitosis of different periodicity by fourier analysis

摘要

Rhythms of cell division with different periods in the mouse small intestinal cryptic epithelium were studied using Fourier analysis. It was found that the proliferative system of the crypt is characterized by an intricate spatial and temporal organization. The amplitude of low-frequency rhythms increases, while the amplitude of high-frequency rhythms decreased in the direction from the crypt bottom to the neck.
