Figure 2. Aberrant mitoses in CKI KD-reactivated myotubes but not in fibroblasts.

(A) MSC-derived myotubes were transfected with siRNAs to p21 and p27. The cells were fixed and stained 46 hours later. Bar  = 25 µm. (B) Serum-starved, quiescent C3H-10T1/2 cells were transfected with siRNA to p21 and p27 and kept in medium containing 0.1% FBS. The cells were fixed and stained 44 hours later. Bar  = 12.5 µm.
