Isolation and culture of neural crest cells from embryonic murine neural tube.
The embryonic neural crest (NC) is a multipotent progenitor population that originates at the dorsal aspect of the neural tube, undergoes an epithelial to mesenchymal transition (EMT) and migrates throughout the embryo, giving rise to diverse cell types. NC also has the unique ability to influence the differentiation and maturation of target organs. When explanted in vitro, NC progenitors under...
متن کاملNeural crest cell lineage segregation in the mouse neural tube.
Neural crest (NC) cells arise in the dorsal neural tube (NT) and migrate into the embryo to develop into many different cell types. A major unresolved question is when and how the fate of NC cells is decided. There is widespread evidence for multipotential NC cells, whose fates are decided during or after migration. There is also some evidence that the NC is already divided into subpopulations ...

نقص لوله عصبی یکی از ناهنجاریهای مادرزادی مهم و شایع می باشد که شیوع آن بیش از ۵/ ۴ در ۱۰۰۰ تولد زنده است. اتیولوژی و پاتوژنز بیماری هنوز ناشناخته است. مطالعات اخیر بر روی حیوانات نشان می دهد که این ناهنجاری ممکن است، ناشی از متابولیسم غیر طبیعی هموسیستئین باشد. در مطالعات اخیر مشخص شده است که پیشگیری از نقص لوله عصبی (NTD) بوسیله اسیدفولیک مؤثر می باشد.
متن کاملMigration and differentiation of neural crest and ventral neural tube cells in vitro: implications for in vitro and in vivo studies of the neural crest.
During vertebrate development, neural crest cells migrate from the dorsal neural tube and give rise to pigment cells and most peripheral ganglia. To study these complex processes it is helpful to make use of in vitro techniques, but the transient and morphologically ill-defined nature of neural crest cells makes it difficult to isolate a pure population of undifferentiated cells. We have used s...
متن کاملA role for rhoB in the delamination of neural crest cells from the dorsal neural tube.
The differentiation of neural crest cells from progenitors located in the dorsal neural tube appears to involve three sequential steps: the specification of premigratory neural crest cell fate, the delamination of these cells from the neural epithelium and the migration of neural crest cells in the periphery. BMP signaling has been implicated in the specification of neural crest cell fate but t...
