Fig. 4From: Transplantation of human bone marrow mesenchymal stromal cells reduces liver fibrosis more effectively than Wharton’s jelly mesenchymal stromal cellsα-Smooth muscle actin expression (α-SMA) in the hepatic stellate cells (HSCs) under various culture conditions. a α-SMA in unactivated HSCs (left), HSCs activated with TGF-β1 (left center), TGF-β1-activated HSCs treated with BM-MSCs conditioned medium (BMCM) (right center), and TGF-β1-activated HSCs treated with WJ-MSCs conditioned medium (WJCM) (right). b Quantification of collagen levels on the unactivated HSCs, TGF-β1-activated HSCs, and activated HSCs treated with conditioned medium derived from bone marrow and Wharton’s jelly.
