Sentences with phrase «in embryonic development from»

Not exact matches

This process is mediated by biological molecules called growth factors, which are proteins that occur naturally in our cells and guide processes ranging from embryonic development to healing.

Because development often reprises stages of evolution, the growth of embryonic ears in tandem with the jaw is no accident: the sound - transmitting middle ear bones that are a distinguishing feature of mammals evolved from what used to be gill arches in fish and jawbones in reptiles.

Other speakers proposed that all of these traits, from hormone levels to craniofacial features, have a common root in early embryonic development.

Turtles are the only beasts in the animal kingdom that don hard outer shells formed from bone during embryonic development, and a scarcity of ancient turtle fossils has made it difficult to track the evolution of this unique trait.

Generating neurons from stem cells (either embryonic stem cells or those «induced» to revert back to an embryo - like state) requires adding signaling molecules to the cells at critical moments in their development.

According to the researchers, these findings suggest that differences in shape from cell - to - cell within a tissue are key to their ability to jam and unjam — and that this process appears to drive biological events including embryonic development, wound healing, and, potentially, cancer cell invasion.

Corey Nislow's laboratory develops and uses cutting edge tools to address this central question: how can we understand the biological commonalities in all of the life sciences; from embryonic development, to the spread of infectious diseases to better ways to treat cancer.

In the new research, Pollen and co-first author Tomasz Nowakowski, PhD, also a postdoctoral researcher in the Kriegstein lab, partnered with Fluidigm Corp. to develop a microfluidic approach to map out the transcriptional profile — the set of genes that are actively producing RNA — of cells collected from the VZ and SVZ during embryonic developmenIn the new research, Pollen and co-first author Tomasz Nowakowski, PhD, also a postdoctoral researcher in the Kriegstein lab, partnered with Fluidigm Corp. to develop a microfluidic approach to map out the transcriptional profile — the set of genes that are actively producing RNA — of cells collected from the VZ and SVZ during embryonic developmenin the Kriegstein lab, partnered with Fluidigm Corp. to develop a microfluidic approach to map out the transcriptional profile — the set of genes that are actively producing RNA — of cells collected from the VZ and SVZ during embryonic development.

2007 also saw one of the most game - changing developments in the stem cell field; researchers learned how to create cells like embryonic stem cells, but instead of coming from an embryo these cells are created from adult cells, potentially cells from any tissue in the human body.
