Extended Data Fig. 3: Defects in spermatogenesis in PIWIL1-deficient male golden hamsters.

a, Testis and cauda epididymis of 1-week-old (1w), 4-week-old (4w) and 10-week-old (10w) from wild-type and PIWIL1-deficient golden hamsters. Scale bars = 10 mm. b, Sperm from the 10w wild-type and PIWIL1-deficient cauda epididymis. Scale bars = 50 µm. c, d, Hematoxylin and eosin-stained 4w (c) and 15w (d) testis sections of wild-type and PIWIL1m/m hamsters, respectively. Scale bars = 100 µm. e, anti-PIWIL1 antibody staining of testis sections of 15-w wild-type and PIWIL1m/m hamsters. Scale bars = 100 µm.
