Details
While not a spatial proteomics data, it was analysed with the
pRoloc package.
During mammalian preimplantation development, the cells of the
blastocyst's inner cell mass differentiate into the epiblast and
primitive endoderm lineages, which give rise to the fetus and
extra-embryonic tissues, respectively. Extra-embryonic endoderm (XEN)
differentiation can be modeled in vitro by induced expression of GATA
transcription factors in mouse embryonic stem cells. Here, we use this
GATA-inducible system to quantitatively monitor the dynamics of global
proteomic changes during the early stages of this differentiation
event and also investigate the fully differentiated phenotype, as
represented by embryo-derived XEN cells. Using mass spectrometry-based
quantitative proteomic profiling with multivariate data analysis
tools, we reproducibly quantified 2,336 proteins across three
biological replicates and have identified clusters of proteins
characterized by distinct, dynamic temporal abundance profiles. We
first used this approach to highlight novel marker candidates of the
pluripotent state and XEN differentiation. Through functional
annotation enrichment analysis, we have shown that the downregulation
of chromatin-modifying enzymes, the reorganization of membrane
trafficking machinery, and the breakdown of cell-cell adhesion are
successive steps of the extra-embryonic differentiation process. Thus,
applying a range of sophisticated clustering approaches to a
time-resolved proteomic dataset has allowed the elucidation of complex
biological processes which characterize stem cell differentiation and
could establish a general paradigm for the investigation of these
processes.
