Oligodendroglial cell death in jimpy mice: an explanation for the myelin deficit
PE Knapp, RP Skoff and DW Redstone
Neuroglial cell death was investigated in 3 white matter tracts of jimpy
and normal mice. In normal animals, glial death during development ranged
from 0.5 to 2.7% of the total glial population. The number of dying glial
cells was significantly higher in jimpy animals at times corresponding with
oligodendroglial proliferation and the onset of myelination in each tract.
At certain ages, over 10% of the glial population were pyknotic at the
light-microscopic level. Dying glial cells that were identified
ultrastructurally presented the characteristics of oligodendrocytes.
Premature death of oligodendrocytes presents a simple explanation for the
gross deficits of myelin in jimpy animals. The shortened life span of the
jimpy oligodendrocyte may preclude the elaboration of a normal myelin
sheath. The jimpy model may prove to be a valuable tool in delineating a
role for normal neuroglial cell death during the development of the nervous
system.
