  • The cells that go awry in HSCR are a subset of what are called neural crest cells, embryonic cells that spring from the developing brain and spinal cord in mice or humans and then travel long distances to form, among others, structures in the face and heart, smooth muscle, and neurons of the peripheral nervous system, including those that innervate the gut.

  • The earlier study, published in January of 2012, reported that mice missing one of their two copies of a gene called Tcof1 not only produced fewer neural crest cells but that colonization of the gut by the remaining cells proceeded slowly compared to normal mice. (stowers.org)
  • That paper showed that neural crest cells don't seem to have a defined time window to colonize the entire gut as long as they do it by birth," says Trainor, suggesting that for humans this is a good thing in terms of potential intervention. (stowers.org)
  • In the latter, the researchers eliminated one copy of Tcof1 along with one copy of another gene known to govern neural crest formation and proliferation, Pax3 . (stowers.org)
  • Double mutant mice showed serious defects: fewer neural crest cells migrated out of the embryonic spinal cord, and the ones that remained underwent increased cell death as they traveled toward the gut. (stowers.org)
