a The comparison of the average doubling time (DT) of GCs (n = 24), the GC-derived tumor cell line COV434 (experiment carried in triplicates) and the long-term growing granulosa cell line GC8 (experiment carried in triplicates) that were isolated and cultivated in the same way as other GC lines but presented a different characteristics. b Comparison of the average cumulative population doublings (PD) of GCs (n = 24), GC8 (n = 3) and the GC-derived permanent tumor cell line COV434—cumulative data
