Latent TGF-b1 expression in normal and keloid fibroblasts. A. Western blot demonstrating expression of latent TGF-β1 in normal (NF1) and keloid (KF1, KF2, KF3, KF4, KF5) fibroblasts with (+HA) or without 72 hour hyaluronic acid treatment. Actin staining was used as a loading control. Molecular weights in kDa are given in numbers. B. Graph represents densitometric analysis of percent TGF-b1 expression normalized to the actin control. Statistical analysis was done using a two-tailed unpaired student's t-test. p <0.05 was used as a criterion for significance.
