Effects of FSH on retinol uptake and metabolism in granulosa cells. a Semi-quantitative LC-MS analysis of retinoid levels in mouse follicular granulosa cells in the presence or absence of FSH for 24 h. b Real-time PCR analyses of the expression of genes in retinol uptake and metabolism pathways in mouse follicular granulosa cells in the presence or absence of FSH for 24 h. Data are presented as means ± SEM, n = 4. *p < 0.05, **p < 0.01
