Cardiogenic differentiation of Sca-1⁺ cells in vitro. (A–L) Immunodetection of Sca-1 and troponin I in differentiating NMCs isolated from FGF-2^+/+ mice in the absence (None) or presence of FGF-2 and maintained for 1 (A–C), 2 (D–F), or 3 weeks (G–I) in differentiation medium. (M–R) The same experiment using NMCs isolated from FGF-2^–/– mice maintained for 3 weeks in differentiation medium. Original magnification, ×40.
