CELLS OF THE BONE TISSUE – 4
Osteoclasts
Large multinucleated cells involved in bone tissue resorption.
Their cytoplasm is usually strongly stained in red by a mixture of hematoxylin and eosin.
It is often possible to observe at the interface between an osteoclast and the bone surface a thin, slightly concave space called Howship’s lacuna, highlighted in light brown and indicated by an arrow in the upper figure. Observe cytoplasmic extensions of the osteoclast that protrude into this space.
The osteoclast cytoplasm is highlighted in light blue and nuclei in dark blue.
Osteocytes inside the matrix are highlighted in green or brown.
Osteoblasts on the surface of the bone matrix highlighted in light brown.
