reproductive system
N |
• embryos show normal mammary gland development
|
nervous system
|
• cerebellum has decreased number of fissures compared to conditional Gli2 knockouts
|
|
• only the five cardinal lobes of cerebellum can be discerned; other lobules do not form
|
|
• decreased number of lobules (abnormal foliation) is observed
|
nervous system
|
• progenitors for motor neurons, V1 and V2 interneurons are present but intermixed indicating abnormal spatial patterning
|
|
• increased proliferation of ventral spinal cord progenitors at E10.5
|
|
• floor plate progenitors are missing
|
|
• incorrect positioning and number of V0-V2 and motor neuron progenitors at E9.5
|
|
• ventral spinal cord is expanded resulting in a wavy appearance
|
|
• distribution of motor neurons varies at E12.5
|
|
• reduction in the number of differentiated motor neurons but an increase in their progenitors
|
|
• absence of V3 progenitors and interneurons, however V0-V2 cells are formed
• fewer V2, V1, and V0 interneurons are seen in the hindlimb
|
|
• absence of V3 progenitors and interneurons, however V0-V2 cells are formed
