The team used bacterial toxins to either kill or silence brain cells in developing mouse embryos, which were just balls of around 100 to 200 cells, known as blastocysts. The cells targeted were ...

This process, known as blastocyst complementation, involves injecting rat stem cells into mouse blastocysts—early-stage embryos lacking the ability to develop a pancreas due to genetic mutations.

Recent study aimed to investigate the association between blastocyst biopsy for preimplantation genetic testing (PGT) and ...
