Quantitative Analysis of Protein Expression to Study Lineage Specification in Mouse Preimplantation Embryos

Nestor Saiz¹, Minjung Kang¹, Nadine Schrode¹, Xinghua Lou¹, Anna-Katerina Hadjantonakis¹

¹Developmental Biology Program, Sloan Kettering Institute

This protocol presents a method to perform quantitative, single-cell in situ analysis of protein expression to study lineage specification in mouse preimplantation embryos. The procedures necessary for collection of blastocysts, whole-mount immunofluorescent detection of proteins, imaging of samples on a confocal microscope, and nuclear segmentation and image analysis are described.

¹Developmental Biology Program, Sloan Kettering Institute

Protocols to generate hPSC mutant lines using the iCRISPR platform and to differentiate hPSCs into glucose-responsive β-like cells are described. Combining genome editing technology with hPSC-directed differentiation provides a powerful platform for the systematic analysis of the role of lineage determinants in human development and disease progression.
