tenascin


Also found in: Wikipedia.

ten·as·cin

(ten-as'sin),
A protein that is present in the mesenchyme that surrounds epithelia in organs undergoing development in embryos; believed to participate in inducing differentiation of epithelia.

tenascin

/te·nas·cin/ (ten´ah-sin) a glycoprotein of the extracellular matrix, isolated from a variety of embryo and adult tissues, including epithelial sites, smooth muscles, and some tumors.

tenascin C

A secreted extracellular matrix protein encoded by TNC on chromosome 9q32-q34, which has a spatially and temporally restricted tissue distribution. It plays a key role in guidance of migrating neurons and axons during development, synaptic plasticity and neuronal regeneration.

tenascin

adhesive glycoprotein contributing to the cell-to-basal lamina-to-matrix interface.
