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.
Feeder-free Derivation of Neural Crest Progenitor Cells from Human Pluripotent Stem Cells Nadja Zeltner1, Fabien G. Lafaille2, Faranak Fattahi1, Lorenz Studer1 1Developmental Biology, Center for Stem Cell Biology, Sloan-Kettering Institute for Cancer Research, 2St. Giles Laboratory of Human Genetics of Infectious Diseases, The Rockefeller University Neural crest (NC) cells derived from human pluripotent stem cells (hPSC) have great potential for modeling human development and disease and for cell replacement therapies. Here, a feeder-free adaptation of the currently widely used in vitro differentiation protocol for the derivation of NC cells from hPSCs is presented.
