WebSep 29, 2006 · Osteocytes subjected to 1 h of PFF produced conditioned medium (CM) that significantly inhibited the proliferation of cultured osteoblasts ().This inhibition was visible as early as day 1 and was most pronounced at day 5. The inhibition was statistically significant at each time point, with p values less than 0.05, 0.01, and 0.001 at days 1, 2, and 5, … WebIntroduction. The normal rate of osteocyte apoptosis thought as the default fate for osteocytes could result in the removal of the “dead” bone through autophagic programmed cell death, which permits the self-renewal of the bone cells and preserving of bone strength 1,2. Nevertheless, a bulk of apoptotic osteocytes are implicated in several key …
