Schwann cell development in embryonic mouse nerves.
Previously we proposed that Schwann cell development from the neural crest is a two-step process that involves the generation of one main intermediate cell type, the Schwann cell precursor. Until now Schwann cell precursors have only been identified in the rat, and much remains to be learned about these cells and how they generate Schwann cells. Here we identify this cell in the mouse and analy...
متن کاملDerivation of Multipotent Mesenchymal Precursors from Human Embryonic Stem Cells
BACKGROUND Human embryonic stem cells provide access to the earliest stages of human development and may serve as a source of specialized cells for regenerative medicine. Thus, it becomes crucial to develop protocols for the directed differentiation of embryonic stem cells into tissue-restricted precursors. METHODS AND FINDINGS Here, we present culture conditions for the derivation of unlimit...
متن کاملRole of N-cadherin in Schwann cell precursors of growing nerves.
In the present paper, we determine the localization and developmental regulation of N-cadherin in embryonic rat nerves and examine the role of N-cadherin in this system. We also identify a major transition in the architecture of embryonic nerves and relating it to N-cadherin expression. We find that in early embryonic nerves, N-cadherin is primarily expressed in Schwann cell precursors. Pronoun...
متن کاملDevelopment of the Schwann cell lineage: from the neural crest to the myelinated nerve.
The myelinating and nonmyelinating Schwann cells in peripheral nerves are derived from the neural crest, which is a transient and multipotent embryonic structure that also generates the other main glial subtypes of the peripheral nervous system (PNS). Schwann cell development occurs through a series of transitional embryonic and postnatal phases, which are tightly regulated by a number of signa...
متن کاملIn vivo analysis of Schwann cell programmed cell death in the embryonic chick: regulation by axons and glial growth factor.
The present study uses the embryonic chick to examine in vivo the mechanisms and regulation of Schwann cell programmed cell death (PCD) in spinal and cranial peripheral nerves. Schwann cells are highly dependent on the presence of axons for survival because the in ovo administration of NMDA, which excitotoxically eliminates motoneurons and their axons by necrosis, results in a significant incre...
