After 20 days of differentiation, vesicular neurospheres selectively expressed multiple retinal transcription factor genes appropriate for the OV stage of retinogenesis, whereas nonvesicular neurospheres expressed transcription factors indicative of the embryonic forebrain. Many transcription factor genes associated with retinal development were present at higher levels in vesicular vs. nonvesicular neurospheres. Nonvesicular neurospheres, on the other hand, expressed higher levels of transcription factors implicated in early forebrain development.  Taken together, results indicated that the vesicular and nonvesicular neurospheres harbored retinal progenitor cells and early forebrain populations, respectively.
