IL6 and skin basal cell carcinoma: In addition, in comparison to AT-MSC, BCC-CAF showed the high upregulation of genes related to CAF differentiation (e.g., IL6 [3.23-fold increase]; Fig. 2I), and fibroblastic cell markers (e.g., FAP [3.11-fold increase] and vimentin [2.41-fold increase]; Fig. 2I).
