Pluripotent cells show the unlimited self-renewal capacity and the potential to differentiate into the cell lineages originating from three germ layers. To date real pluripotent stem cell lines, able to generate germ line chimeras, have been established in rodents. Large domestic animals, especially pig, due to their considerable anatomical and physiological similarities with humans are thought to...
The aim of the present work was to determine the relative transcript abundance of the oestrogen receptor alpha (ERα) and beta (ERβ) gene in long-term cultures (up to 18 days) of pig granulosa cells (GC) obtained from small (1-2 mm; SF-GC) and large (5-7 mm; LF-GC) follicles. GC were cultured in the presence of 10% foetal calf serum (FCS) and one of the following growth factors: leukaemia inhibitory...
The aim of the study was to investigate the effect of testosterone (T) and dihydrotestosterone (DHT) applied alone or in combination with antiandrogen (flutamide) on proliferation, progesterone secretion and telomerase activity (TA) of pig granulosa cells (GC) derived from small (1-3 mm; SFGC) and large (5-7 mm; LF-GC) ovarian follicles. Cells were treated with investigated factors for 48 h. 5α-DHT...
