tumorigenesis
• mice develop ocular tumors of photoreceptor cell origin (J:60231)
• beginning at 4 weeks of age, photoreceptor cells are replaced by hyperchromatic cells of small size with scanty cytoplasm (J:60231)
• by 10 weeks of age tumors invade the optic nerve, ciliary body, iris and vitreous (J:60231)
• mice develop ocular tumors of photoreceptor cell origin (J:60231)
• beginning at 4 weeks of age, photoreceptor cells are replaced by hyperchromatic cells of small size with scanty cytoplasm (J:60231)
• by 10 weeks of age tumors invade the optic nerve, ciliary body, iris and vitreous (J:60231)
• 25% of mice develop midbrain tumors (J:60231)
• by 2 weeks of age the pineal gland is replaced by tumor cells that resemble a highly differentiated retinoblastoma in 2 week old mice (J:60231)
• cells are large and atypical with numerous abnormal mitotic figures (J:60231)
• tumor cells form Homer Wright rosettes (J:60231)
• by 8-10 weeks of age tumors cover and invade the cerebral and cerebellar hemispheres (J:60231)
