Injection of male ES cell lines into mouse blastocysts generally distorts gender ... By identifying the genders of chimeric pups at an early stage, researchers can determine whether it is ...

Stem cell-based embryo models, such as blastoids, serve as models of the blastocyst and are invaluable tools for studying embryogenesis and early human development. However, the variability in ...

involves injecting rat stem cells into mouse blastocysts—early-stage embryos lacking the ability to develop a pancreas due to genetic mutations. Subsequently, the rat stem cells differentiate ...
