The Osteocytes are the most commonly found cells in mature bone tissue. They have a stellate shape and are approximately 7 micrometers in diameter by 15 micrometers in length. In mature bone, osteocytes and their processes reside inside spaces called lacunae or pits and canaliculi, respectively. Although osteocytes have reduced synthetic activity, they are actively involved in the routine turnover of bone matrix, through various mechanosensory mechanisms. They destroy bone through a rapid, transient (relative to osteoclasts) mechanism called osteocytic osteolysis. Blood vessels on the other hand are responsible for oxygen and nutrient delivery and waste removal, via the circulating blood. Vascular pores are relatively large and can be picked up even with medium-resolution scans. However, detecting osteocyte lacunae requires much higher resolution. Fortunately, current microCT systems allow scanning bone at sub-micron resolution allowing 3D characterization of intracortical vascular porosity and osteocyte lacunae.
