Cell viability after 1, 2, and 3 weeks of culture (mean ± SD, n = 4 triplicates). CTR−: basal culture medium (without RANKL, M-CSF, PTH); CTR+: differentiated medium (with RANKL, M-CSF, PTH). Scheffé post hoc multiple comparison test between PBMCOVX and PBMCSHAM for each culture condition: 1st week, CTR− PBMCOVX versus PBMCSHAM ***p < 0.0005; 2nd week, CTR− PBMCOVX versus PBMCSHAM ***p < 0.0005; 3rd week, CTR− PBMCOVX versus PBMCSHAM ***p < 0.0005
