Title: Crypt cells
Post by: DoctorBeaver on 07/11/2005 22:28:14

Can anyone tell me what they are, please? I know they are an indicator of cell turnover, but I'd like a proper definition. I've searched the net for the last 3 hours & still haven't managed to find out.

I understand they're the cells in the 'crypts' of the villi in teh small intestine. the villi are protrustions of the cell membrane that basically increase the surface area of the cells, so increasing absorption. these cells divide at a higher rate to replace the cells at the tips of teh villi, which gradually wear away. this is all stuff I learned many years ago, so there may be gaps or even errors, so I'd advice more reading!

Thanks, Lindsay, that fits in with what I've learned so far so it's probably right [:)]
