A further 25 days in medium
containing FGF2 and Noggin mediated the derivation and expansion of RPCs which had a similar global
gene expression pattern to cells of the embryonic day 14 (E14) mouse retina.
An equally consistent
pattern of
gene expression is observed in the set of ICM markers (
contained within Group 2 in Figure 4A, Figure 4C, and Figure S3).
