Investigators developed a simple culture protocol under which the adult murine inguinal adipose tissue-derived stromal vascular fraction (Ad-SVF) reproducibly transdifferentiates into beating cardiomyocyte (CMs) without induction. The beating CMs showed the striated ventricular phenotype of cardiomyocytes and synchronised oscillation of the intracellular calcium concentration among cells on day 28 of Ad-SVF primary culture.
