«Clarifying the interplay between bone cells in bone remodeling: Spatiotemporal intercellular interactions between mature osteoblasts and mature osteoclasts in bone homeostasis in vivo demonstrated.»
Too much p53 in bone - making cells called osteoblasts dials down a gene, H19, and a related protein, decorin, that would otherwise help stem cells mature (differentiate) to become normal osteoblasts.
