简介：
Overview
This study explores a serum-free oxygenated culture system for mouse embryos, demonstrating that mid-gestation embryos can develop morphologically similar to in utero conditions. The method allows for the manipulation of embryonic development while avoiding unknown serum components.
Key Study Components
