Expression of insulin-like growth factor 1 (IGF1), IGF2, IGF-receptor 1 (IGF1R), prolactin receptor (PRLR), progesterone receptor (PGR) and oestrogen receptor alpha (ERα, ESR1), as determined by Real Time (TaqMan) PCR. Canine primary stromal cells were cultured for 24, 48 and 72 h in the presence of increasing dbcAMP concentrations. One-way ANOVA (24 h in IGF1 P < 0.01, 72 h in IGF1 P < 0.02; 72 h in IGF2 P < 0.03; 24 h in PRLR P < 0.0003, 48 h in PRLR P < 0.0001, 72 h in PRLR P < 0.001; 48 h in ERα P < 0.02, 72 h in ERα P < 0.004), followed by the Tukey-Kramer Multiple Comparison Test was applied; all samples were compared against the non-treated control in each group. Different letters indicate P < 0.05. Numerical data are presented as the mean ± standard deviation (SD)
