Protocol for culture of zebrafish developing ovaries as an ex vivo system for investigating early oogenesis and ovarian development
A fundamental understanding of early oogenesis is lacking, and zebrafish serve as an excellent model for investigation, based largely on in vivo approaches. We present a protocol for long-term zebrafi...
