Interactions between pituitary cell lineages direct tissue architecture and size

Project description:Organ architecture is established during development through specific cell:cell contacts. The mechanisms responsible for these specific cell interactions remain poorly understood. In order to address this question, we used the anterior pituitary gland that harbors five different and interdigitated hormone-secreting homotypic cell networks. We now report that blocking differentiation of the first lineage to arise during pituitary development, the corticotrope cells, leads to pituitary hypoplasia with a major effect on the somatotrope cells that are fewer, with less secretory granules and a loss of cell polarity. These somatotrope cell phenotypes are dependent on gene dosage for the corticotrope-restricted transcription factor Tpit. In addition, the Tpit-deficient pituitary is hyper-vascularized. Single cell transcriptomics identifiy corticotrope and somatotrope regulatory and signaling pathways that may underlie cell:cell communications responsible for these phenotypes. Collectively, the results indicate that the corticotrope cell network is an important paracrine signalling center regulating pituitary architecture and size.

Cell-to-cell gene expression variability followed by reinforcement progressively segregates lineages in the early mouse embryo

Project description:Mammalian embryonic development begins with the specification and segregation of the two extra-embryonic lineages, trophectoderm and primitive endoderm, from the pluripotent embryonic lineage, the epiblast. To establish a map of epiblast (EPI) versus primitive endoderm (PrE) lineage segregation which occurs within the inner cell mass (ICM), we comprehensively characterised the gene expression profiles of individual inner cells during blastocyst development. Lineage represents the two embryonic cell lineages: the epiblast (EPI), and the primitive endoderm (PE), which are segregated within the inner cell mass(ICM) during blastocyst development.

Dynamic proteomic profiling of extra-embryonic endoderm differentiation in mouse embryonic stem cells

Project description:During mammalian pre-implantation 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 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 extra-embryonic endoderm (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 extra-embryonic endoderm differentiation. Through functional annotation enrichment analysis, we have shown that the downregulation of chromatin-modifying enzymes, the re-organization 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.

Single-cell Transcriptomics Reveals the Divergent Developmental Lineage Trajectories during Human Pituitary Development

Project description:The anterior pituitary gland plays central roles in body growth, reproduction, metabolism and the stress response. In this study, we performed single-cell RNA-sequencing (scRNA-seq) of 4,113 individual cells from human fetal pituitaries. We characterized divergent developmental trajectories with distinct transitional intermediate states in five hormone-producing cell lineages. Furthermore, we characterized the cellular heterogeneity of pituitary stem cells, identifying a hybrid epithelial/mesenchymal state and an early-to-late state transition. These analyses define a single-cell resolution roadmap for human pituitary development.

ChIP-chip from pregnant female mouse pituitary with POU1F1 (PIT-1)

Project description:POU1F1 regulates, in the pituitary, the development of the prolactin-, growth hormone- and thyrotropin ß-expressing lineages and the expression of these hormone in the mature pituitary through the direct regulation of their promoters. Besides these functions, POU1F1 is also involved in other cellular processes in the pituitary, such as cell division and survival, but the genomic targets involved in these actions are not known. The present ChIP-chip study identified a large number of hitherto unknown potential direct targets that might be involved in these actions, such as Tcf4, Lmo4, Pax6, Trp53 etc. ChIP-chip was done from pregnant female mouse (C57Bl/6J) pituitary (3 pools of 12 pituitary anterior lobes, corresponding to three biological replicates) with POU1F1 (PIT-1)

ATACseq in primary pituitary cells

Project description:Deployment of a cell-specifying enhancer repertoire by the pioneer factor Pax7 The establishment and maintenance of cell identity depends on implementation of stable cell-specific chromatin landscapes. Pioneer transcription factors establish new cell fate competences by triggering chromatin remodeling during development. Here, we used pituitary cell specification to define the salient features of pioneer action. Comparison of purified pituitary cells of different lineages showed that chromatin accessibility differs at enhancers rather than promoters. The pioneer factor Pax7 specifies one pituitary lineage identity by opening a specific repertoire of enhancers that are distinct from the myogenic targets of Pax7. Pax7 binds its pioneer targets rapidly and days before chromatin remodeling and gene activation. Finally, enhancers opened by Pax7-dependent chromatin remodeling exhibit loss of DNA methylation and they acquire long term epigenetic memory. The present work identifies enhancer pioneering as a critical feature for cell fate specification and maintenance.
