Sentences with phrase «tissue during embryonic development»

On rare occasions ectopic thyroid tissue (abnormal migration of thyroid tissue during embryonic development) can give rise to lesions in the tongue, ventral neck, cranial mediastinum and heart base.

All stem cells are immature cells known for their ability to multiply indefinitely and give rise to progenitor cells that mature into specific cell types that populate the body's tissues during embryonic development.

Not exact matches

Scientists have focused for decades on the role of biochemical cues in embryonic development, Campàs said, because no techniques existed to measure the mechanical cues that cells are exposed to during the formation of tissues and organs.

During embryonic development, undifferentiated stem cells accumulate methyl groups and other epigenetic marks that funnel them into one of the three germ layers, each of which gives rise to a different set of adult tissues.

Animals such as salamanders and planaria regenerate tissues by rekindling genetic mechanisms that guide the patterning of body structures during embryonic development.

The method could also help biologists understand how tissues change subtly during embryonic development — and even help map the maze of neurons that wire the human brain.

The ability of a fertilized egg to generate both embryonic and extra-embryonic tissues is referred to as «totipotency,» an ultimate stem cell state seen only during the earliest stages of embryonic development.

However, malformation of skeletal bones during embryogenesis also occurs in FOP patients and illustrates that the underlying genetic mutation occurs in a gene with functional importance in regulating chondro - osseous differentiation during embryonic skeletal development as well as in adult musculoskeletal tissues.

They are present during the early stages of embryonic development and possess the ability to become, or «differentiate,» into almost any tissue within the body.

The researchers also identified new links between aggressive meningioma proliferation and activation of an intercellular signaling pathway called Wnt — which typically plays a role during embryonic development and tissue formation.

Most Alkbh1 deficient mice die during embryonic development, and survivors are characterized by defects in tissues originating from the ectodermal lineage.

Eight HARs showed differences in their enhancer activity when the human mutations were present.4 These differences modify how genes were expressed in the developing limb (HAR2, 2xHAR114), eye (HAR25), and central nervous system (2xHAR142, 2xHAR238, 2xHAR164, 2xHAR170, ANC516 / HARE5).4, 10 Because relatively few time points have been examined, it is likely that an even higher percentage of the tested HARs are active enhancers at some point during embryonic development or in adult tissues, possibly with human - chimp differences.

Prof. Dr. Ivan Martin's research group at the Department of Biomedicine has now been able to demonstrate that by forcing certain molecular events occurring during the embryonic development of articular cartilage it is possible to generate stable cartilage tissue from adult human mesenchymal stem cells.
