nervous system
• fewer mature oligodendrocytes in the developing spinal cord at P7 without increased apoptosis
• however, the number of mature oligodendrocytes is normal at P14 to P70
|
• small-sized neurons, not large-sized motor neurons are prominent in the ventral horn of the spinal cord unlike in wild-type mice
|
• fewer NeuN+ neurons in the ventral horn of the spinal cord at P7, but not other time points
• however, the number of Neu+ neurons in the whole spinal cord is normal
|
homeostasis/metabolism
• following spinal cord injury, mice exhibit reduced myelin basic protein expression compared with wild-type mice
• however, mice exhibit normal locomotor function as measured by BMS score after spinal cord injury
