It is well known that mast cells produce and release biologically active substances such as histamine, heparin, proteases, leukotrienes, cytokines, chemokines and growth factors. According to the avail-able scientific literature on that topic this is

Detailed mast cell classification is reported in humans and rats, however such classification is not available in porcine common hepatic duct. It is interesting to find out whether mast cells in common hepatic duct are able to produce ghrelin, which

Due to the similar pattern of ghrelin localisation in human and porcine intestine, swine are described as a suitable animal model for experiments related to ghrelin and its receptors. In a previous study of ours, the presence of ghrelin immunoreactiv
