We are using US origin FBS from gibco after heat inactivation for MC3t3 E1 (preosteoblasts) maintenance and differentiation. Can we shift it to south american origin FBS?
Yes you can. In my experiments, I was not able to find any major differences in expression profiles or differentiation capacity of MC3T3-E1 between sources of fetal bovine serum. However, within each experiment, you have to use the same serum for control and treatment groups when you compare the results for statistical significance.
