Terminal myogenic differentiation in Kras; p16p19null and SmoM2 mouse tumors. (A) Subsets of Kras; p16p19null tumors cells express terminal muscle differentiation markers, actin and desmin. (B) The majority of SmoM2 tumor cells express actin and desmin. Images were taken at 20× (scale bars indicate 100 μm).
