Observation of pharyngeal pouch development in chick embryo with SEM 鸡胚咽囊发生的扫描电镜观察
This research explored the role of pharyngeal pouch endoderm ( PPE) to development ( induction and patterning) of chick ossicle and integration of the ossicle and inner ear by quail-chick chimera. 本研究采用鹌鹑-鸡胚移植法探索咽囊内胚层对中耳听骨发育(诱导/成形)及中耳听骨与内耳整合的作用。
