text_1: Ectopic expression of Sall4, Nanog, Esrrb, and Lin28 generates induced pluripotent stem cells from mouse embryonic fibroblasts more efficiently than other factor combinations.
text_2: Based on tetraploid complementation, we found that ectopic expression of Sall4, Nanog, Esrrb, and Lin28 (SNEL) in mouse embryonic fibroblasts (MEFs) generated high-quality iPSCs more efficiently than other combinations of factors including OSKM.
