  • (20) Apparently, the irradiation with visible light of a low intensity creates an additional proton gradient and thus stimulates a new replication and division cycle in the population of cells whose membranes do not have delta pH necessary for the initiation of these processes.

Pericellular


Definition:

  • (a.) Surrounding a cell; as, the pericellular lymph spaces surrounding ganglion cells.

Example Sentences:

  • (5) The pericellular localization of collagen type IV indicates a survival time of approximately 4 days or more.
  • (6) A unique pattern for a carbohydrate antigen is displayed by cells of the primitive streak; antigenicity is lost with de-epithelialisation and ingression, but is regained in a pericellular distribution on the mesoderm cells that emerge from the primitive streak.
  • (7) We conclude that at least two discrete and widely separated sites in fibronectin with different binding properties--the carboxyl-terminal fibroblast cell-adhesive domain and an amino-terminal matrix assembly domain localized primarily within the first 25 kDa--are required for fibronectin pericellular matrix assembly by fibroblasts.
