  • Vitamin C Promoting Embryonic Stem Cells Co-cultured on Poly 3-Hydroxybutyrate-co-4-Hydroxybutyrate to Differentiating into Myocardiocytes

    ObjectiveTo assess the suitability of P (3HB-co-4HB) combined with embryonic stem cells (ESCs) for myocardial patch formation and whether adding vitamin C would improve inductivity or not. Method We extracted mouse embryonic fibrous cell from three clean female white Kunming mouses at a mean body weight of 37.5 grams. We recovered and cultured mouse ESCs. Those mouse embryonic stem cells were obtained from Shanghai Institutes of Biological Sciences. We took pendant-drop method to form embryonic bodies (EBs) and co-cultured them with myocardial patch. The experimental group were cultured in the substate with vitamin C while the control group were cultured in the substate without vitamin C. We immunostained the myocardial patch and observed them by scanning electron microscope. We calculated the differentiation efficiency and mapped the distribution curve of induction time. ResultsThe scattergram showed that the differentiation efficiency increased gradually. The differentiation efficiency of the group with vitamin C was 71.1% and the group without vitamin C was 17.8%. There was a statistical difference between the two groups (P < 0.05). ConclusionOn the biological patch of P (3HB-co-4HB), ESCs could grow, proliferate, and differentiate into myocardial cell and adding vitamin C into it could improve the differentiation efficiency.
