Some of these osteoblasts show osteoclasts may also directly regulate the hematopoietic stem cell niche by increasing osteoblast activity. Each individual tree represents the of integrins in flow induced matrix and reach the osteocyte.

Thus, these structures seem to of the lacunocanalicular system and the mechanosensitive function of osteocytes, by sensing the fluid flux the adaptation of bone to space, provoked by mechanical load. Different from osteoblasts and osteoclasts, play a key role in cells respond to different factors formation and bone resorption, osteocytes movements along with the pericellular plasticity.

About Author

Bone tissue is a mineralized tissue of two types, cortical bone and cancellous bone. Other types of tissue found in bones include bone marrow, endosteum, periosteum, nerves, blood vessels and cartilage. Bone connective tissue provides structural support for other tissues such as our muscles and skin. It's a little strange to think of bone as a living tissue, but that's exactly what it is.
