The expression of MT2A, MTG2 and Calcitonin genes in response to P4. The expression of three genes including MT2A (a), MTG2 (b) and calcitonin (c) in PrMyoN and PrMyoF cells was determined by real-time PCR after P4 treatment (1.0 ng/ml) for 3 days. N = PrMyoN cells without treatment, Np = PrMyoN cells after adding P4, F = PrMyoF cells without treatment, Fp = PrMyoF cells after adding P4. These experiments were performed with 10 different cultured cell specimens
