We present a low-cost, do-it-yourself system for complexmammalian cell culture under dynamically changing medium formulations by integrating conventional multi-well tissue culture plates with simple microfluidic control and system automation. We demonstrat ...

Cnidarian-dinoflagellate photosynthetic symbioses are fundamental to biologically diverse and productive coral reef ecosystems. The hallmark of this symbiotic relationship is the ability of dinoflagellate symbionts to supply their cnidarian host with a wid ...
The definitive endoderm (DE) was first defined as the innermost germ layer found in all metazoan embryos. During development, it gives rise to a vast array of specialized epithelial cell types lining the respiratory and digestive systems, and contributes t ...
Sox17 is essential for both endoderm development and fetal hematopoietic stem cell (HSC) maintenance. While endoderm-derived organs are well known to originate from Sox17-expressing cells, it is less certain whether fetal HSCs also originate from Sox17-exp ...
Nodal and its co-receptors of the EGF-CFC family are essential during chordate development, both to maintain pluripotent progenitor cells and to subsequently coordinate their allocation to the different germ layers. How these distinct Nodal activities are ...
TAF4 (TATA-binding protein-associated factor 4) and its paralogue TAF4b are components of the TFIID core module. We inactivated the murine Taf4a gene to address Taf4 function during embryogenesis. Here we show that Taf4a(-/-) embryos survive until E9.5 whe ...
Accurate spatio-temporal control of Hox cluster genes expression is critical for the proper organization of body structures during vertebrate embryogenesis. In the limbs, Hoxd genes are critical in setting up the proximodistal and anteroposterior axes. Sev ...
Axis formation and allocation of pluripotent progenitor cells to the germ layers are governed by the TGF-β-related Nodal precursor and its secreted proprotein convertases (PCs) Furin and Pace4. However, when and where Furin and Pace4 first become active ha ...
Previous attempts to recapitulate embryogenesis in a developmentally relevant context started with aggregates composed of a few thousand ESCs, termed embryoid bodies (EB), that upon induction of differentiation reveal a surprising level of autonomous cell ...
In humans, mice, and other mammals key internal organs such as the gut, the lungs, the pancreas, and the liver all derive from the same embryonic tissue: the endoderm. The development of all of these structures thus depends on a same set of early cells, an ...
