A zinc finger-dependent, PRDM13-driven mechanism regulates retinal progenitor cell fate from mouse embryonic stem cells via WNT signaling

GSE295608 Mus musculus Expression profiling by high throughput sequencing 4 samples Submitted 2025/04/24 Platform GPL24247
Summary
The transcriptional regulation underlying eye field (retinal primordium) development requires precise control, yet the mechanisms guiding lineage-specific differentiation within the central nervous system (CNS) remain incompletely understood. Using neuroectoderm (NE) organoids derived from mouse embryonic stem cells, we investigate the role of PRDM13 in eye field specification. We demonstrate that Prdm13 expression inhibits RX+ eye field fate but permits non-eye field NE differentiation, an effect dependent on its first and second zinc finger domains. Prdm13 activates the WNT/β-catenin signaling pathway during differentiation, leading to downregulation of key transcription factors crucial for establishing the eye field. Pharmacological inhibition of WNT signaling abolishes PRDM13-mediated suppression, restoring RX+ eye field differentiation. Our work reveals a previously undescribed PRDM13-WNT signaling axis that regulates lineage-specific neural differentiation of embryonic stem cells.
