NUMERICAL DENSITY OF CONVEX, NON-BRANCHING ORGANELLES IN ANISOTROPICALLY ORIENTED CELLS - CILIA IN TANGENTIAL CHONDROCYTES

A stereological expression relating the mean number of organelle profiles per cell profile, N̄p, to the mean number of organelles per cell, N̄c, is first derived and then tested for cilia in tangential articular chondrocytes where N̄c is known to be 1.0 N̄c derived sterologically for this organelle-cell model is 1.19. This close approximation of the estimate to a known value provides empirical evidence of the usefulness of the derived stereological expression.
