The disclosure refers to a use of transforming growth factor-β and bovine whey protein extract. The transforming growth factor-β and the bovine whey protein extract are used for manufacturing a composition for preventing capsular contracture after receiving breast implantation. The composition comprises transforming growth factor-β (TGF-β). Thereby, the composition can relieve and prevent patients from capsular contracture after receiving breast implantation.本發明是關於一種轉化生長因子-β及乳清蛋白提取物之用途。所述轉化生長因子-β及乳清蛋白提取物是用於製備防止假乳植入術後莢膜攣縮的組成物。其中,組成物包含轉化生長因子-β(transforming growth factor-β,TGF-β)。藉此,組成物可減緩、防止患者假乳植入術後莢膜攣縮(capsular contracture)之適應症。無
