Exencephaly, spina bifida, mild edema, and gonadal abnormalities with XY gonadal sex reversal in Map3k4byg/Map3k4byg embryos

mortality/aging

reproductive system
N
• XX gonads appear normal
• testes development is disrupted as confirmed by abnormal expression of the Sertoli cell marker Sox9
• some mice exhibit a reduction in the number or absence of testes cords and irregular morphology compared with wild-type mice
• in some mice
• cultured gonadal XY explants fail to form testis cords or express testis-specific markers but express ovarian markers unlike wild-type samples
• in XY gonads, proliferation of cells in the coelomic region is severely reduced compared to in wild-type mice
• in XY gonads, migration of mesonephric cells to form testes cords is impaired compared to in wild-type mice
• in XY mice
• XY mice develop ovotestis that develop testes cords at the central portion while the poles are ovarian in appearance and marker expression
