Fig. 2From: Induction of substantial myocardial regeneration by an active fraction of the Chinese herb Rosa laevigata MichxaFRLM-enhanced cardiogenic differentiation of cultured MSCs. The majority of the vehicle-treated MSCs (14Â days) under low-power filed (CtrlL) and high-power filed (CtrlP) phase contrast microscope remained flat, irregular, asymmetrical and low-refractive with few MHC-positive (GFP) stained cells (CtrlG). In contrast, approximately 30Â % of the cultured MSCs in the aFRLM-treated wells (14Â days) under low-power filed (TrtL) and high-power filed (TrtP) became relatively elongated and had a high-refractive myocyte-like phenotype (yellow arrowheads) with approximately 30Â % of these myocyte-like cells being positively (GFP) stained with MHC specific antibodies (TrtG)Back to article page
