Figure 3
Effects of TJE, FTJ and PEP on collagen production in HDFs. Cells were cultured with TJE, FTJ, and PEP at a concentration of 1 μg/mL for 24 h. The supernatant was collected from each well and procollagen type 1 c-peptide (PIP) was measured using an ELISA kit. Data are presented as mean ± standard deviation of three independent experiments ; vs. control group.
