A new cell culture resource for investigations of reptilian gene function.

The establishment of CRISPR/Cas9 gene editing in Anolis sagrei has positioned this species as a powerful model for studies of reptilian gene function. To enhance this model, we developed an immortalized lizard fibroblast cell line (ASEC-1) for the exploration of reptilian gene function in cellular processes. We demonstrate the use of this cell line by scrutinizing the role of primary cilia in lizard Hedgehog (Hh) signaling.
