5 Proliferon
This is my fifth presentation which summarizes the current knowledge of cell proliferation kinetics. Please start with the first. Actually I presented a theory of streaming epithelium. It has an atom and an engine that propagates epithelia in he body.
Atom is the epithelial proliferating unit (EPU)
Engine is the two compartment cell renewal system
However this theory is still incomplete since lacking an important ingredient of epithelia, lamina propria mucosae.
Epithelial function unit (EFU) contains epithelium and lamina propria.
Both stream as a whole from the crypt and upward toward the villus tip.
This streaming structure is called a proliferon.
