Protocol for generating mouse morula-like cells resembling 8- to 16-cell stage embryo cells.

ABSTRACT

Generating cell types with properties of embryo cells with full developmental potential is of great biological importance. Here, we present a protocol for generating mouse morula-like cells (MLCs) resembling 8- to 16-cell stage embryo cells. We describe steps for induction, via increasing Stat3 activation, and the isolation of MLCs. We then detail procedures for segregating MLCs into blastocyst cell fates and how to create embryo-like structures from them. This system provides a stem-cell-based embryo model to study early embryo development. For complete details on the use and execution of this protocol, please refer to Li et al.1.
