Disturbed morphogenesis of testis cords in neonatal Ddb1 cKO mice. (A) Hematoxylin stained testicular sections from 15 dpc, 18 dpc, 0 dpp, and 2 dpp control and cKO mice. In 0 and 2 dpp cKO testes, the cords exhibit gross enlargement of cross-sectional diameter, red stars indicate much larger testis cords in cKO mice, scale bars = 50 μm; (B) the diameters of testis cords shown in (A); and (C) the number of testis cords per transverse section in (A). Data were presented as mean ± S.E.M. ** p < 0.01, Student’s t-test.
