Adipocyte differentiation-related protein (ADFP) also called Adipophilin is associated with the globule surface membrane material. ADFP (Adipophilin) occurs in a wide range of cultured cell lines, including fibroblasts, endothelial and epithelial cells. ADFP may be a possible indicator for the identification of specialized differentiated cells containing lipid droplets and for diseases that link to fat-accumulating cells.
