Title: From osteoblast to osteocyte 4
Description:
Electron micrographs of osteblasts and osteocytes in rabbit, desmal ossification.
(A+B+C):
(1): Osteoblasts.
(2): Subosteoblastic layer.
(3): Bone matrix.
(4): Canaliculi.
(5): Osmiophilic lamina. (thin very dense outline of the lacuna closed to the osteocyte).
The osteoblast in (A) has an ample cytoplasm with abundant RER, Golgi vesicles.
The cell in (B) is a resorptive osteocyte. There is no osmiophilic lamina and there is a paucity of organelles and RER profiles.
The cell in (C) appears in the transition from quiescent stage to formative osteocyte. The osteocyte still has an osmiophilic lamina but the amount of organelles increases, including Golgi areas and dense lysosomal structures.
