WebDec 29, 2004 · The AC stimulatory agonist adrenomedullin inhibited collagen synthesis in CF that overexpressed AC6 but not in controls. Thus, AC stimulation blunts collagen synthesis and, in parallel, the transformation of adult rat CF to myofibroblasts. AC overexpression enhances these effects, “uncovering” an inhibition by adrenomedullin. WebNov 23, 2024 · Genetic lineage tracing and flow cytometry revealed distinct subsets of wound bed myofibroblasts that express smooth muscle actin and collagen. The most abundant populations were CD26-expressing APs and a subset with high cell surface levels of CD29 (CD29 High). Although transcriptomic analysis revealed that each myofibroblast …
WebSep 22, 2024 · The Smith team has a theory about what might be causing fibrosis. They expected that a stiff environment due to a high collagen level could turn the progenitors into myofibroblasts that produce collagen. More collagen makes the matrix even more stiff.
