Bulk RNAseq REX-1 RFP mESC 2019

This experiment examines how increasing stress (sorbitol) can override normal stemness (NS) conditions, which LIF maintains, causing lineage imbalance and otherwise affecting cells in the early embryo. It also compares NS to normal differentiation (ND) (without LIF). D3 are from 8 blastocysts of 129/Sv+/+ strain mice germ line competent 1. No sex is given as these may actually be a product of different sexes of the 8 blastocysts. The D3 cells were obtained for ATCC (American Type Culture Collection). 1.
