Scientists used CRISPR editing to make the world's first genetically modified snakes, giving new insight into how the reptiles develop their patterned scales
For the first time ever, scientists have created genetically modified snakes. The CRISPR-edited reptiles are providing new insight into how corn snakes develop their precisely patterned scales.
Scientists from Geneva wanted to know exactly how and why these"near-perfect hexagonal pattern[s]" developed on the dorsal scales located on the snakes' backs and flanks, but not on the ventral scales that form as a single row on the animals' underbellies. Tzika pointed to lizards with a mutated EDA gene, which were previously studied in her university's lab, as an example of a reptile that never developed scales.
