A recent study in Nature Cell Biology identified guinea pigs as promising small animals to model preimplantation development, a critical step in human embryogenesis. Stem cells provide ...

The findings are published in Nature Cell Biology. By analyzing guinea pig embryos using advanced single-cell RNA sequencing, the researchers mapped gene expression patterns during embryo development.
