Efficient Method for Liposome-Based Gene Transfer in Cattle Embryos.

In vitro embryo production (IVP) in cattle is crucial for advancing genetic enhancement and preserving valuable genetic lineages, enabling precise genetic modifications and gene studies through modern techniques. Successful genetic manipulation in cattle embryos requires efficient delivery of exogenous DNA/RNA molecules. This research investigates the efficacy of a single embryo culture system for developing genetically modified zona-free (ZF) embryos and examines the use of liposome-based SAMTOR target siRNA transfer in these individually cultured ZF embryos.
