The CB021 embryonic stem cell line was established using day 3.5 blastocysts from a cross between a hemizygous B6.Cg-Tg(APPswe,PSEN1dE9)85Dbo/Mmjax female (MMRRC#<a href="https://www.jax.org/strain/005864"">034832-JAX</a>) and a male homozygous for Mapttm1(EGFP)Klt. This cross resulted in biological replicates that are hemizygous for Tg(APPswe,PSEN1dE9)85Dbo (MMRRC#037552, #037553);all lines are heterozygous for Mapttm1(EGFP)Klt. These cell lines have been proven useful in in vitro experiments directed towards differentiation of ESCs to cortical neurons. The APPswe and PSEN1dE9 transgenes are also available as ESC lines generated from various crosses (see MMRRC#037546-#037550 and MMRRC#037564-#037568). Cell lines were derived and maintained on mitomycin-C treated mouse embryonic fibroblast feeder cells (MEFs) derived from C57BL/6J embryos. This cell line was not germline tested.

The CB021 embryonic stem cell (ESC) line was established from a cross between a B6.Cg-Tg(APPswe,PSEN1dE9)85Dbo/Mmjax (APP/PS1) hemizygous female (MMRRC#<a href="https://www.jax.org/strain/005864"">034832-JAX</a>) and a C57BL/6 congenic male homozygous for Mapttm1(EGFP)Klt. This cell lines may be useful in in vitro experiments directed towards differentiation of ESCs to cortical neurons expressing AD-relevant mutations.
