Abstract

Osteocytes are defined as cells embedded within the bone matrix. As it is difficult to extract these cells from bone, the biology of these cells was largely ignored for decades. Once tools became available to study these cells, surprising functions have been identified. These functions include regulation of skeletal homeostasis, mechanosensation and mechanotransduction, and as endocrine cells secreting factors that can target distant organs, such as kidney and muscle. It has recently emerged that mutations in osteocyte biomarkers coding for hormones and factors are responsible for a number of bone conditions and diseases. As the osteocyte is the longest-lived bone cell, it should be considered a memory cell that can undergo senescence with aging. Clearly bone health is dependent on the function and health of the osteocyte.
