Influence of Mechanical Stimuli on Schwann Cell Biology
Schwann cells are the glial cells of the peripheral nervous system (PNS). They insulate axons by forming a specialized extension of plasma membrane called the myelin sheath. The formation of myelin is essential for the rapid saltatory propagation of action potentials and to maintain the integrity of axons. Although both axonal and extracellular matrix (ECM) signals are necessary for myelination...
متن کاملThe role of the desert hedgehog signaling pathway during degeneration and regeneration of peripheral nerves
The desert hedgehog (Dhh) signaling pathway is involved in the development of peripheral nerves (PNs). Dhh-null mice show abnormal neuronal development and perineurial barrier function. As it was previously shown that dhh is mainly expressed in developmental nerves and Sonic hedgehog protein (dhh homologous) has therapeutic effects in neuronal survival, we attempted to investigate the possible ...

متن کاملSchwann Cell–Derived Desert Hedgehog Controls the Development of Peripheral Nerve Sheaths
We show that Schwann cell-derived Desert hedgehog (Dhh) signals the formation of the connective tissue sheath around peripheral nerves. mRNAs for dhh and its receptor patched (ptc) are expressed in Schwann cells and perineural mesenchyme, respectively. In dhh-/- mice, epineurial collagen is reduced, while the perineurium is thin and disorganized, has patchy basal lamina, and fails to express co...
متن کاملSchwann cells as regulators of nerve development.
Myelinating and non-myelinating Schwann cells of peripheral nerves are derived from the neural crest via an intermediate cell type, the Schwann cell precursor [K.R. Jessen, A. Brennan, L. Morgan, R. Mirsky, A. Kent, Y. Hashimoto, J. Gavrilovic. The Schwann cell precursor and its fate: a study of cell death and differentiation during gliogenesis in rat embryonic nerves, Neuron 12 (1994) 509-527]...
