I am trying to differentiate H9c2 cells into cardiomyocytes using 10 nM all-trans-retinoic acid. The cell growth seemed to be decreased after treatment with 10 nM RA. I plated H9c2 cells on T75 (35K/ml) and treated with 10 nM RA containing 1% FBS.
I have two questions.
Q1. Does the cell grow after differentiation or do I have to differentiate everytime to run the experiment?
Q2. Can I switch back to 10% FBS after the cell differentiate or do I need to treat 10 nM RA daily?
