CD14 and osteoporosis: We identified six variables that were predictive for OB differentiation: sex of the donor (p = 0.001), presence of osteoporosis (p = 0.004), intake of vitamin D supplements (p = 0.003), fraction of CD146+ cells (p = 0.004), fraction of ALP+ cells (p = 0.005), and CD14+ cells (p = 0.089).
