#Unit 5. Developmental Biology
  1. Lens induction can be achieved in the presence of optic vesicle after priming of head ectoderm by the anterior neural plate.
  2. The optic vesicle can induce the presumptive head ectoderm to form the lens.
  3. Under the influence of factors secreted by the lens, the optic vesicle becomes retina.
  4. The anterior neural plate primes the head ectoderm via BMP4 and Fgf8 prior to signals from the optic vesicle.
