PG - 102643 LID - S1873-5061(21)00490-6 [pii] LID - 10.1016/j.scr.2021.102643 [doi] AB - Beta2-microglobulin (B2M) is a subunit of human leukocyte antigen class-I (HLA-I) heterodimer that mediates immune rejection through activation of cytotoxic T cells. B2M binding to HLA-I proteins is essential for functional HLA-I on the cell surface. Here, we generated a B2M homozygous knockout somatic cell nuclear transfer-induced embryonic stem cell (SCNT-ESC) line using CRISPR/Cas9-mediated gene targeting. B2M KO cell line, which does not express HLA-I molecules on cell surface, has pluripotency and differentiation ability to three germ layers. This cell line provides a useful cell source for investigating immunogenicity of allogeneic ESCs and their derivatives for tissue regeneration. CI - Copyright (c) 2021 The Author(s).
