polysialic acid (medicine) and intramembranous (medicine)


polysialic acid (medicine)


polysialic acid
Potential regulator of cell cell interactions. Polysialic acid chains in glycoproteins, for example when covalently associated with NCAM, have negative regulatory effects on cell cell contact. The low PSA form of NCAM is thought to promote cell cell contact and enhance fasiculation whereas NCAM with a high PSA content is thought to prevent close membrane membrane apposition.


intramembranous (medicine)


intramembranous


1. Within, or between the layers of, a membrane.

2. Denoting a method of bone formation directly from mesenchymal cells without an intervening cartilage stage (occurring, for example, in the calvaria), as distinguished from intracartilaginous bone formation.
