KIT and intrahepatic cholangiocarcinoma: In humans, a loss of ICC and a reduction in ICC network volume in normal stomach and colon with age have been described,7 while in ageing rats, a reduction in density of ICC has been reported in the proximal colon8 and stomach.9 A reduction in c‐Kit protein levels has also been described in the ageing rat colon.10 No studies to investigate the effects of age on the network volume of ICC in the terminal bowel or in the mouse gut have been performed.
