Actomyosin-based Self-organization of cell internalization during C. elegans gastrulation [PDF]

, 2012
Background: Gastrulation is a key transition in embryogenesis; it requires self-organized cellular coordination, which has to be both robust to allow efficient development and plastic to provide adaptability. Despite the conservation of gastrulation as a

Insights Into Human Development and Disease From Human Pluripotent Stem Cell Derived Intestinal Organoids

Frontiers in Medicine, 2019
In recent years, advances in human pluripotent stem cell (hPSC) biology have enabled the generation of gastrointestinal (GI) organoids which recapitulate aspects of normal organ development.

Endothelial cells instruct liver specification of embryonic stem cell-derived endoderm through endothelial VEGFR2 signaling and endoderm epigenetic modifications

Stem Cell Research, 2018
Liver organogenesis requires complex cell-cell interactions between hepatic endoderm cells and adjacent cell niches. Endothelial cells are key players for endoderm hepatic fate decision. We previously demonstrated that the endothelial cell niche promotes

Gene regulatory network subcircuit controlling a dynamic spatial pattern of signaling in the sea urchin embryo [PDF]

, 2008
We dissect the transcriptional regulatory relationships coordinating the dynamic expression patterns of two signaling genes, wnt8 and delta, which are central to specification of the sea urchin embryo endomesoderm.

Endoderm-Derived Myeloid-like Metaphocytes in Zebrafish Gill Mediate Soluble Antigen-Induced Immunity

Cell Reports, 2020
Summary: Immune cells in the mucosal barriers of vertebrates are highly heterogeneous in their origin and function. This heterogeneity is further exemplified by the recent discovery of ectoderm-derived immune cells—metaphocytes in zebrafish epidermis ...

Molecular recording of mammalian embryogenesis. [PDF]

, 2019
Ontogeny describes the emergence of complex multicellular organisms from single totipotent cells. This field is particularly challenging in mammals, owing to the indeterminate relationship between self-renewal and differentiation, variation in progenitor

The lncRNA DEANR1 Facilitates Human Endoderm Differentiation by Activating FOXA2 Expression

Cell Reports, 2015
Long non-coding RNAs (lncRNAs) regulate diverse biological processes, including cell lineage specification. Here, we report transcriptome profiling of human endoderm and pancreatic cell lineages using purified cell populations.

Gene expression analysis of bovine embryonic disc, trophoblast and parietal hypoblast at the start of gastrulation [PDF]

, 2017
In cattle early gastrulation-stage embryos (Stage 5), four tissues can be discerned: (i) the top layer of the embryonic disc consisting of embryonic ectoderm (EmE); (ii) the bottom layer of the disc consisting of mesoderm, endoderm and visceral hypoblast

Endoderm and heart development [PDF]

Developmental Dynamics, 2000
Since the first half of the 20th century, experimental embryologists have noted a relationship between endoderm cells and the development of cardiac tissue from mesoderm. During the past decade, the accumulation of evidence for an obligatory interaction between endoderm and mesoderm during the specification and terminal differentiation of myocardial ...
