Abstract

Cadherins are important adhesion molecules that mediate adhesions and communications between cells. These molecules participate in the formation and maintenance of multicellular organisms including the stem cells. E-cadherin is one of the classic cadherins which is reported to be essential for the survival and self-renewal of embryonic stem cells. Moreover, it could induce cell proliferation inhibitory signaling to regulate cell proliferation. In our study, we over-expressed and silenced E-cadherin in NSCs by lentiviral ways. Transgenic cells were confirmed by both quantitative RT-PCR and western blot. Results of MTT assay showed that over-expression of E-cadherin could enhance the cell activity. Furthermore, we performed Transwell chamber assay to analyze its role in regulation of cell migration. The results showed that the migration percent of over-expression cells was lower than control. Our results indicated that E-caherin would maintain the stemness of NSCs and reduce cells migration.

Cell Migration

Cell migration is involved in a variety of physiological and pathological processes such as embryonic development, cancer metastasis, blood vessel formation and remoulding, tissue regeneration, immune surveillance and inflammation. Here is the latest research.

Adhesion Molecules in Health and Disease

Cell adhesion molecules are a subset of cell adhesion proteins located on the cell surface involved in binding with other cells or with the extracellular matrix in the process called cell adhesion. In essence, cell adhesion molecules help cells stick to each other and to their surroundings. Cell adhesion is a crucial component in maintaining tissue structure and function.

Cadherins and Catenins

Cadherins (named for "calcium-dependent adhesion") are a type of cell adhesion molecule (CAM) that is important in the formation of adherens junctions to bind cells with each other. Catenins are a family of proteins found in complexes with cadherin cell adhesion molecules of animal cells: alpha-catenin can bind to β-catenin and can also bind actin. β-catenin binds the cytoplasmic domain of some cadherins. Discover the latest research on cadherins and catenins here.

Adherens Junctions

An adherens junction is defined as a cell junction whose cytoplasmic face is linked to the actin cytoskeleton. They can appear as bands encircling the cell (zonula adherens) or as spots of attachment to the extracellular matrix (adhesion plaques). Adherens junctions uniquely disassemble in uterine epithelial cells to allow the blastocyst to penetrate between epithelial cells. Discover the latest research on adherens junctions here.
