Fig. 5From: Identification of a window of androgen sensitivity for somatic cell function in human fetal testis cultured ex vivoEffects of manipulating androgen production in ex vivo cultured human fetal testis tissue on the expression of the germ cell marker OCT4. Expression of the germ cell markers OCT4 in fetal testis samples treated with ketoconazole (10−6 M) and hCG (1 IU/ml) for 2 weeks in ex vivo culture. Images representative for the expression in each age group and treatment. Counterstaining with Mayer haematoxylin; the scale bar corresponds to 50 µmBack to article page
