It is expressed by cells forming the basement membrane of calcifying tissue indicating that, as in mammals, it may play a role in osteoblast differentiation. PTHrP induced downregulation of osteonectin mRNA in vitro in scales, a mineralizing tissue with bone-like metabolism. This indicates a means to redirect calcium to activities such as vitellogenesis when this ion is in high demand.engOsteonectinExtracellular matrixFish skeletonPTH-related peptideScalesIsolation and characterization of piscine osteonectin and downregulation of Its expression by PTH-related proteinjournal article2014-05-09http://dx.doi.org/10.1359/JBMR.041201
