GnRH3 serves as the key hypophysiotropic regulator of reproduction, yet the heterogeneity within its migratory neuronal population has remained unclear in 7 dpf zebrafish. By profiling nuclei from 7 dpf Tg(gnrh3:EGFP) larvae, this study provides the first single-cell-transcriptomic characterization of migrating GnRH3 neurons in 7 dpf zebrafish and offers new insights into their developmental organization and functional specialization.2026/07/15GSE309816GSM928254124995309816Danio rerio[42415515]
