ARTICLE HIGHLIGHTS
Research background
Loss and/or dysfunction of interstitial Cajal-like cells (ICLCs) in the gallbladder may promote cholesterol gallstone formation by decreasing gallbladder motility.
Research motivation
Absorption of supersaturated cholesterol in bile by the gallbladder wall might be the cause of loss and/or dysfunction of gallbladder ICLCs.
Research objectives
The present study aimed to evaluate the effect of cholesterol on the proliferation and apoptosis of ICLCs from guinea pig gallbladders.
Research methods
ICLCs from guinea pig gallbladders were isolated and cultured in vitro. The cells were exposed to cholesterol solutions at different concentrations. Cell proliferation, apoptosis rate, and expression of c-Kit protein and mRNA were detected.
Research results
Compared with the control group (no treatment group), the addition of cholesterol significantly decreased the proliferation rates and the expression of c-Kit protein and mRNA in ICLCs. While, the apoptosis rates of cells were increased.
Research conclusions
High cholesterol concentrations can inhibit the proliferation of ICLCs and promote apoptosis, which might be caused by the inhibition of the stem cell factor/c-Kit signaling pathway.
Research perspectives
This is a proof-of-concept study that lacks a mechanical study. The mechanism by which cholesterol regulates the stem cell factor/c-Kit pathway remains unclear and need further investigation.
