The expression of Shh, Ptch1, and Gli1 in the developing caudal spinal cord of fetal rats with ARMs

This study demonstrated that the expression of Shh, Ptch1, and Gli1 in lumbosacral spinal cord was remarkably reduced during late developmental stages in fetal rats with ARMs. These findings offered some important insights into the involvement of the Shh-Ptch1-Gli1 signaling pathway in the pathogenesis of lumbosacral spinal cord maldevelopment in rat fetus with ARMs, which leads to complications after procedures for ARMs.
