egr is not essential to regulate stem cell numbers in response to protein starvation. (A,B) Testes immunostained for Vasa (germ cells, red), co-stained for Zfh-1 (CySCs and early cyst cells, green) and FasIII (hub, blue). Asterisks and arrows indicate GSCs and CySCs, respectively. Flies were starved from 18 days. (C) The number of GSC and CySC after starvation for 0–18 days. Data is presented as mean ± SD. The number of testes in each time point is between 15 and 34.
