N normal phenotype
reproductive system
abnormal sperm flagellum morphology ( J:163862 )
• in more than 50% of sperm from mice with high percentage chimerism
• in less than 5% of sperm from mice with medium to low chimerism
• however, heads are normal
abnormal outer dense fiber morphology ( J:163862 )
• high percentage chimeric mice produce elongating spermatids that lack one or more entire outer dense fibers (ODFs) in their midpiece and principal piece
• elongating spermatids that show thinning of ODFs
abnormal sperm axoneme morphology ( J:163862 )
• some bent tails from mice with high percentage chimerism lack one or more axonemal microtubule doublets compared to in wild-type cells
abnormal sperm midpiece morphology ( J:163862 )
• some spermatid midpieces from mice with high percentage chimerism lack up to 5 entire outer dense fibers compared with wild-type cells
• some midpieces from mice with high percentage chimerism fuse to the principal pieces unlike in wild-type mice
kinked sperm flagellum ( J:163862 )
• more than 50% of sperm have bent tails unlike in wild-type mice
