Functional properties of regenerating skeletal muscle following LIF administration

Abstract

We tested the hypothesis that periodic systemic administration of the myogenic cytokine leukemia inhibitory factor (LIF) enhances the functional recovery of regenerating skeletal muscle following bupivacaineinduced degeneration. LIF had no effect on functional capacity or regenerating myofiber size in rat muscles at 7, 14, or 21 days post-injury. The results do not support exogenous administration of LIF as a treatment for acute muscle injury, but a more frequent dosing regimen should be tested. (C) 2000 John Wiley and Sons, Inc.
