Figure 1. Neural differentiation of P19 murine embryonic carcinoma cells.
A. Undifferentiated P19 cells. B. Embryonic body (EB) formation, P19 cells treated with RA for 2 days and plated on non-adherent Petri dishes. C. EB bodies plated on day 3 on adherent tissue culture dish, note migration of cells from EB and formation of neurites in individual cells (arrows).
