Western blot analysis of xenografted immature and adult testes at 1-and 2-wk-post grafting for expression of EGFR and STAT pathway proteins. Protein expression in 6-day-old and 10-wk- old donor testes before grafting (T0) are presented as starting material. Representative blot (A) and densitometry analysis of (B) EGFR, (C) JAK1, (D) STAT3, and (E) STAT3 –pSer705 protein. Y-axis represents intensity of bands relative to GAPDH. Data are presented as mean ± SEM. Bars with different letters are significantly different at P < 0.05.
