abstract：:Injury to the mammalian spinal cord is accompanied by a delayed, secondary wave of oligodendrocyte apoptosis that arises several days after the initial injury. A strong candidate to support oligodendrocyte survival after spinal cord injury is the pleiotropic cytokine, leukemia inhibitory factor (LIF). In vitro, LIF po...
