Argentine scientists from Kheiron SA have successfully created the first five genetically modified horses using CRISPR-Cas9, a tool known for its precision and speed in gene editing. This breakthrough has implications for farming, animal care, and genetic improvement, positioning Argentina as a leader in genetic biotechnology.

CRISPR-Cas9, which won the Nobel Prize in Chemistry in 2020, has revolutionized genetic engineering by allowing precise changes to DNA to enhance traits or correct genetic errors. In the case of the genetically modified horses, changes were made to the MSTN gene to improve muscle growth and speed, benefiting horse sports like polo. This technology also offers potential applications in medicine, agriculture, and disease control.

Argentina’s regulatory framework for genetic biotechnology, overseen by the National Directorate of Bioeconomy and CONABIA, ensures that projects adhere to strict safety and ethical standards. The success of Kheiron SA’s genetically modified horses showcases the potential for future projects in Argentina, with CRISPR-Cas9 offering opportunities for advancements in various fields, including agriculture, medicine, and space exploration.
