Pig Stem Cells Created

... Further tests confirmed the cells were capable of differentiating into the cell types that make up the three layers in an embryo -- endoderm, mesoderm and ectoderm -- a characteristic of all embryonic stem cells. The discovery will make it easier for researchers to develop embryonic stem cells ...

World first: Chinese scientists create pig stem cells

... confirmed that they were, in fact, stem cells capable of differentiating into the cell types that make up the three layers in an embryo endoderm, mesoderm and ectoderm a quality that all embryonic stem cells have. The information gained from successfully inducing pluripotent stem cells (iPS cells) ...

Pourquié Lab uncovers mechanism contributing to appropriate formation of the spine

... in each of these species the smaller the vertebrae precursors are along the body length, the more vertebrae are formed." The presomitic mesoderm is the middle layer of the three cell layers that form an early embryo. It increases in size as the somites form and then gradually shrinks until it ...

Embryonic pathway delivers stem cell traits

... appears to program the metastatic ability of some breast cancers. Mani knew that during embryonic development, FOXC2 expression is restricted to mesoderm and mesoderm-derived cells when they are in an undifferentiated state, and its expression disappears once these cells differentiate. Similarly, his ...

Oregon researchers find trigger gene for muscle development

... which means it is important for initiating, in this case, development. The UO researchers found that muscle formation begins in an embryo's mesoderm when Smarcd3 interacts correctly with two other transcription-factors known as Fgf and Ntl. This specific time-sensitive alignment, the researchers ...

Brain Regulation Present Even In Spineless Creatures

... the ectoderm of a developing embryo. However, a discovery in Drosophila – fruit flies – has softened that assumption. Cells arising from the mesoderm rest in a layer on top of the fruit fly's nervous system, Tublitz explained. "These cells have all of the properties of nerve cells." A slide shown ...

Caltech researchers get first look at how groups of cells coordinate their movements

... in a living embryo. "This is the first time we've been able to see mesoderm cells within a developing Drosophila embryo," says Angelike Stathopoulos, ... as well. For instance, while scientists had known that the cells in the mesoderm tended to divide twice during gastrulation, they didn't know if this was ...

Pourquié lab links beta-catenin gradient to process of somite formation

... of several major signaling pathways (the gradient) in the presomitic mesoderm (PSM). The PSM is the middle layer of the three cell layers that form an ... Beta-catenin protein gradient in the PSM is critical in regulating mesoderm maturation. Real-time imaging experiments also demonstrated that, ...

U of MN researchers turn cord blood into lung cells

... cell that can be expanded in culture, then differentiated into different types of tissue representative of all three embryonic lineages, endoderm, mesoderm and ectoderm. In this series of experiments, McKenna and his group cultured the MLPC and differentiated it into the lung cells, an endoderm-type ...

Making a face: A new and earlier marker of neural crest development

... of proteins, in situ hybridization and multiplex RT-PCR of mRNAs -- that formation of neural crest cells in chick embryos is independent of both mesoderm and neural tissues. They also identify, Pax7, as an early marker of neural crest formation and prove that its function is required in the earliest ...

Gladstone scientists identify role of tiny RNAs in controlling stem cell fate

... one of the three basic tissue layers in mammals and other organisms. Activity of either miR-1 or miR-133 in ES cells caused genes that encourage mesoderm formation to be turned on. Equally important, they caused other genes that would have told the cell to become ectoderm or endoderm to turn off. For ...

In most protostomes cells simply fill in the interior of the gastrula to form the mesoderm (schizocoelous development), but in deuterostomes it forms through evagination of the endoderm, called enterocoelic pouching. Deuterostomes also ...
