Ascorbic Acid and Fibroblasts

Dear Gautam,
It's nice to see the blunt question of differentiation in such cells. I
assume you mean in culture?

I don't have an answer, but we've been working on differentiation in intact
embryos, and find that each step of differentiation seems to be triggered
by an observable wave that crosses a tissue. It would be interesting to
learn whether similar waves accompany differentiation in tissue culture.
Perhaps ascorbic acid would alter differentiation waves? A couple of key
papers are listed below.

Best, -Dick Gordon
