TGFβ3 knockdown in human CSSC. a Human CSSC were transfected with hTGFβ3 siRNA or scrambled sequences. After co-culture with RAW cells under M1 phase in a Transwell system for 48 h, naïve hCSSC and hCSSC transfected with scrambled sequences showed similar TGFβ3 upregulation, whereas cells with TGFβ3 siRNA transfection showed reduced expression (decreased by 70–84%) of hTGFβ3. Similar results were obtained in two separate experiments. b The reduced hTGFβ3 expression was specific for si-TGFβ3 transfection, while there was no changes for scrambled sequences. The expression of hTGFβ1 remained unchanged with TGFβ3 knockdown in CSSC. Mean and SD are calculated from triplicate experiments
