Experimental work examining angiogenic responses during muscle and tendon healing reported increased expression of angiogenesis-associated markers such as vascular endothelial growth factor (VEGF), CD34, and factor VIII within injured tissues following BPC-157 exposure [6]
The addition of L-NAME partly abolished the effect of BPC 157 [123]

Animal studies have demonstrated BPC-157's cytoprotective effects against NSAID-induced gastric lesions, alcohol-induced stomach damage, stress ulcers, and models of inflammatory bowel disease (ulcerative colitis and Crohn's disease)
