Abstract

Heart disease remains the leading cause of morbidity and mortality worldwide. Induced pluripotent stem cells (iPSCs) have the ability to differentiate into cardiomyocytes (CMs), rendering this cell type to be a promising pre‑cursor of cardiomyocytes for cell‑based cardiac regeneration. Obtaining CMs with a high yield and purity coupled with improved subsequent survival could prove to be invaluable for the future cell replacement therapeutic strategies. Rho‑associated protein kinase (ROCK) is involved in a wide range of fundamental cellular functions and serves significant roles in cardiac physiology. In the present study, human (h)iPSC‑CMs were generated from iPSCs by including glycogen synthase kinase 3β and Wnt inhibitors in the basal culture media. The possible effect of Y27632, a ROCK inhibitor, on hiPSC‑CMs was then investigated. hiPSC‑CMs of high purity were harvested with >96% of cells expressing cardiac troponin T. Additionally, treatment with 10 µM Y27632 significantly improved the viability of dissociated hiPSC‑CMs. The effects of ROCK inhibitors Y27632 and fasudil, on the proliferation and apoptosis of hiPSC‑CMs were also examined. Treatment with ROCK inhibitors markedly enhanced hiPSC‑CM proliferation, by up to 2.5‑fold, whilst Y27632 treatment reduced apoptosis in hiPSC‑derived CMs under serum starvation and suspension by suppressing the expression of caspase‑3. Taken together, data from the present study indicated that ROCK kinase inhibitors effectively improved the cultural system of hiPSC‑derived CMs.
