Electronic Thesis and Dissertation Repository
Radiofibrosis of the breast makes satisfactory breast tissue reconstruction challenging and is associated with complications. Autologous fat grafting can improve surgical outcomes but fat retention is variable. We developed RHAMM peptide mimetics (NPI-110) that decrease tissue fibrosis and increase mammary fat pad adipogenesis by promoting the differentiation of mesenchymal progenitor cells into adipocytes. We tested the efficacy of NPI-110 in a rat model of radiation-induced mammary fat pad fibrosis. Effects of radiation and NPI-110 were quantified by visible skin changes, fat pad volume estimates using high frequency ultrasound, mRNA expression of genes involved in fibrosis (Collagen-1:Collagen-1, TGFß1) and adipogenesis (PPARγ, …
