Figure 4. Expression of cath-D during adipogenesis in human(A) Micrographs of human adipocytes. Human preadipocytes isolated fromsubcutaneous adipose tissue digested with collagenase and separated from thestromal vascular fraction were grown for 0, 3, 7 and 14 days in the presence of theadipogenic medium as illustrated in the micrographs. A representative experiment isshown.(B) Cath-D protein expression during adipogenesis. Protein expression of cath-D andHSL was analysed by immunoblotting after the indicated time following induction ofthe differentiation process (panel a). Two independent experiments (panel a, left andright panels) are presented. NS, non specific band showing sample loading.Quantification of cath-D expression in non-differentiated adipocytes at day 0 (D0)and in differentiated adipocytes at days 7 and 14 (D7, D14) is shown in panel b.Exp; experiment.
