In a recent issue of Arthritis Research and Therapy Lari and colleagues found that osteoclasts developed from a proliferative CD14 CD16- subset in healthy controls. These cells took on the morphology of osteoclasts expressed mRNA for osteoclast-related genes and excavated pits on bone wafers. These findings provide new insights into monocyte diversity and provide evidence that osteoclast precursors arise from a small proliferating monocyte population in controls. Additional studies are needed in patients with inflammatory arthritis .Since these cells aside from their capacity to stretch out prolongations also are capable of consuming foreign bodies we will subsume them under the joint name of fagocytes sic . Ellie Metchnikoff 1884 In a recent issue of Arthritis Research and Therapy Lari and colleagues provide evidence that osteoclast precursors arise from a novel subset of proliferating monocytes 1 . Research in this area originated with the seminal observations of Metchnikoff regarding the central importance of phagocytosis to human physiology which culminated in a Noble Prize and laid the groundwork for the field of innate immunity at the opening of the last century 2 .
