Fig. 1. Models for retina primordium formation in vertebrate
embryos. The outline illustrates the boundary of the neural plate and
the filled circles represent retina primordia. (A) The two separate
retina primordia model. (B) A diagram of Stockard’s model of how a
single primordium spreads and separates into two retinae. Some of
Stockard’s results were directly contradicted by later studies of
Adelmann (1929a,b). (C) This is essentially the same as Figs 1, 2 and
4 of LePlat (1919). (D) A schematic representation of Adelmann’s
model. It was not determined whether midline cells could migrate
laterally. (E) An illustration of the forebrain field model. Eyes are
presumably the default fate of this field (Corner, 1966; Boterenbrood,
1970). Image published in: Li H et al. (1997) Copyright © 1997. Image reproduced with permission of the publisher and the copyright holder. This is an Open Access article distributed under the terms of the Creative Commons Attribution License. Larger Image Printer Friendly View |
