Within at most 2 days, the heart has transformed into a single endocardial conduit extending between still paired venous and arterial vessels (Fig.1; see ref.15). The single channel has the embryonic left ventricle as its caudal, and the embryonic right ventricle as its cranial component. Th...
China has made progress in its space life science research as human embryonic stem cells aboard the Tiangong space station have differentiated into primitive hematopoietic stem cells. The research on human embryonic stem cells was conducted as part of a 6-to-15-day experiment ...
Human early development sets the stage for embryonic and adult life but remains difficult to investigate. A solution came from the ability of stem cells to organize into structures resembling preimplantation embryos—blastocysts—that we termed blastoids. This embryo model is available in unlimited num...

The multi-functional teneurins sit on the surface of cells and bind to other proteins on the surface of other cells, working on embryonic development, guiding nerve cell axons to the right place to make connections with other nerve cells, and helping these connections, or synapses, form. ...
Sex-Specific Gene Expression Differences Are Evident in Human Embryonic Stem Cells and During In Vitro Differentiation of Human Placental Progenitor Cells The placenta is a short-lived tissue required for Camille,M.,Syrett,... - 《Stem Cells & Development》 被引量: 0发表: 2018年 ...
The differentiation of hPSCs along the mesothelium lineage described here is consistent with the generation of this cell type during embryonic development. The approach described in this report shows that SplM progenitors are efficiently specified along the mesothelium lineage by a combination of BMP,...
Human cerebral organoids generated from human embryonic stem cells (hESCs) and human induced pluripotent stem cells (hiPSCs) have enormous potential for the study of human brain development and neurological diseases [1,2,3]. For example, three-dimensional organoids have been used as a model to ...
The causes of embryonic arrest during pre-implantation development are poorly understood. Attempts to correlate patterns of oocyte gene expression with successful embryo development have been hampered by the lack of reliable and nondestructive predictors of viability at such an early stage. Here we repo...
