Figure 1. Effects of DMC-HA and Curcumin on the cell viability of primary keloid fibroblasts. (A) Immunocytochemistry and flow cytometry revealed primary keloid fibroblasts expressed Vimentin and CD90 which were major markers of fibroblast; (B) Cell viability of primary keloid fibroblasts was assessed using the CCK-8 assay following treatment with DMC-HA and Curcumin; (C) IC50 of DMC-HA and Curcumin on primary keloid fibroblasts.
