cell models (IMAGE) Rice University Caption Images produced by Rice scientists illustrate changes in ectodermal “fate” composition as a result of cellular signaling control. Depending on which signals are inhibited versus encouraged, colonies form either radial patterns of neural (cyan), surface ectoderm (magenta) and placodal (red) fates (all represented in the left column), or a ring of neural crest (yellow) at the expense of placodal fates (represented in the right column).
