Abstract

Circulating osteoprogenitor (COP) cells are a relatively newly discovered mesenchymal precursors population in the peripheral blood. While some aspects of their physiology have been documented in vitro, little is known about their behavior in vivo. To facilitate understanding regarding their potential role in the management of musculoskeletal disease, more research into how these cells respond to growth factors and hormones in vivo is still required. To this end, we performed a randomized controlled pilot study investigating the effect of vitamin D supplementation on COP cells in healthy older adults. Twenty-two individuals were recruited and stratified through their baseline vitamin D level..
