Generation of a TRPM8 knockout hESC line (WAe009-A-A) derived from H9 using CRISPR/Cas9.

ABSTRACT

The transient receptor potential cation channel subfamily M member 8 (TRPM8) is a kind of non-selective cation channel which controls Ca2+ homeostasis. Mutations in TRPM8 were related to dry eye diseases (DED). Here we constructed a TRPM8 knockout cell line WAe009-A-A from the original embryonic stem cell line H9 using CRISPR/Cas9 technology, which maybe helpful for exploring the pathogenesis of DED. WAe009-A-A cells possess stem cell morphology and pluripotency as well as normal karyotype, and have the ability of differentiating into three germ layers in vitro.
