In isolated human islets, somatostatin is released in response to increasing glucose concentrations ( Endogenous somatostatin is regulated by intra-islet paracrine influences ( The emerging picture of healthy glucose-insulin secretion coupling is less an isolated -cell driven action, but more a finely tuned paracrine counterbalance between all islet cell components
5,61 As an example, orally administered GSH ethyl ester is able to significantly raise GSH concentrations in the liver, kidney, spleen, pancreas, heart, and lung of the mouse, and in human red blood cells, skin fibroblasts, and several lymphoid cell lines
The two mechanisms are complementary rather than redundant and BPC-157s growth factor receptor upregulation and cytoprotective signalling creating a cellular environment permissive to repair, while TB-500s actin dynamics modulation and PI3K/Akt activation drive the cell migration, vascular ingrowth, and matrix remodelling that execute the repair process at the tissue level
