question: Which are the 3 basic transcription factors that have been used for the direct reprogramming of fibroblasts into cardiomyocytes or cardiomyocyte like-cells?
answer: Direct reprogramming of human cardiac fibroblasts (HCFs) into cardiomyocytes may hold great potential for this purpose. We found that functional cardiomyocytes can be directly induced from fibroblasts by a combination of three cardiac transcription factors, Gata4, Mef2c and Tbx5, in vitro and in vivo.
