Generation of a human extended pluripotent stem cell line (SKLRMe002-A) carrying a doxycycline-inducible Cas9 expression cassette
Summary
Human extended pluripotent stem cell (hEPS) is a novel type of pluripotent stem cell, which possesses bi-potency towards both embryonic and extraembryonic lineages. Here, we generated a hEPS cell line (hEPS1-iCas9-B) from the cell line named hEPS1, carrying a doxycycline-inducible Cas9 expression cassette along with a constitutive reverse tetracycline transactivator (M2rtTA) expression cassette at the AAVS1 locus, thus we could efficiently generate genetically modified hEPS for studies. This cell lined remained self-renewal, differentiation potential and normal karyotype. Meanwhile, it showed robust transcriptional expression of Cas9 with doxycycline induction and could target the site where the sgRNA guided. Copyright © 2022. Published by Elsevier B.V.
