Smurf controls the number of GSCs in adult testes. (A) GSC number in pupal (blue bar) and adult (red bar) testes. GSC numbers decreased from pupae to adult in wildtype (w1118), Smurf heterozygous (Smurf15C/+, Df7149/+) and mad12 Df7149/Smurf15C flies, but not in Smurf15C/Df7149 and Smurf15C/Smurf15C mutants. Average (mean ± SD) was shown. Significance was calculated using two-tailed Student's t-test. ***p<0.001, **p<0.01, np<0.05. n.s.=not significant (p>0.05). Numbers in parenthesis represent the number of testes scored. (B) Hub diameter in pupal (0–4 h APF) and adult (0- to 1-day) testes, showing no significant change (p>0.05) between pupal and adult testes, or among w1118, Smurf heterozygous and Smurf mutant gonads. Hub was identified as FasIII-positive cell cluster at testis apex.
