Figure 4Differentiation of cardiac precursors into functional cardiomyocytes. (
A) RT-PCR analysis of cardiac-specific gene expression in NMCs from
FGF-2+/+ or
FGF-2–/– mice maintained in control (C) or differentiation medium (D) in the absence of FGF-2 (None), after 1 week or 3 weeks in culture. (
B) Quantification of troponin I
+ cells and spontaneously contracting cells in culture of differentiated cardiac precursor from
FGF-2+/+ and
FGF-2–/– mice after 3 weeks in control medium (white bars) or differentiation medium (black bars);
n = 6–10. *
P < 0.05. (
C) RT-PCR analysis of cardiac-specific gene expression in NMCs from
FGF-2+/+ or
FGF-2–/– mice maintained in control or differentiation medium in the presence of FGF-2 or FGF-1 after 1 week or 3 weeks in culture.
