  • Both EGF and LIN-12 prevent precursor cells from adopting the 3 ° fate, which generates non-specialized epidermis. (wormbook.org)
  • The two 2 ° precursor cells generate vulA, vulB1, vulB2, vulC and vulD cells but in mirror symmetric polar patterns: ABCD and DCBA. (wormbook.org)
  • During the L1 and L2 stages, six vulval precursor cells (VPCs) are specified among the 11 Pn.p cells, which are located in the ventral epidermis. (wormbook.org)
  • The evolution of pluripotent stem cell-derived retinal organoids (ROs) has brought remarkable opportunities for developmental studies while also presenting new therapeutic avenues for retinal diseases. (springeropen.com)

  • In particular, vulva development represents a well-understood case in which invariant development arises from multiple cell-cell interactions. (wormbook.org)
