After clinical review of this procedure, we continue to believe that this procedure is appropriately assigned to the APC 5331
Unlike Fe III , Fe II is highly soluble and exchange labile, and recent work reveals that Fe II is bioavailable in these specific niches and recognized to play an important role in nutritional immunity against invading pathogens
Beyond collagen, GHK-Cus effects on the extracellular matrix extend to elastin (30% increase), decorin (302% increase at 1 nanomolar concentration), glycosaminoglycans, dermatan sulfate, and chondroitin sulfate
274,275 This, in turn, diminishes additional downstream effects, including oxidative stress, the secretion of pro-degradative substances, modifications to cell phenotype (hypertrophy, M1/M2 macrophage phenotype, fibrosis), and damage or deterioration of joint cells (apoptosis, senescence)
