“…However, few studies are associated with treatment of alcohol-induced ON. Consistent with previous observations [10,20,24,28,46,50], our data suggest alcohol can induce adipogenesis both in vitro and in vivo, a change found in early stage ON. Adipogenic differentiation is a complex process regulated by many factors.…”

“…However, it is difficult to obtain bone marrow specimens from patients with earlier-stage ONFH because of the absence of subjective symptoms and ethical concerns. Moreover, several researchers have reported reduced BMSC osteogenic differentiation in ONFH patients requiring hip replacement for late-stage disease [9,20]. In our study, BMSCs activities were not found to be significantly different in alcohol-induced ONFH patients who had stopped drinking and those that continued to consume alcohol (data not shown).…”

“…Reports published recently suggest that BMSC numbers and osteogenic differentiation ability are depressed in patients with ONFH, which, in turn, suggests that ONFH is a disease of bone cells and/or BMSCs [5,6,9,20]. In addition, several reports have indicated that BMSC isolation yield and osteogenic capacity are related to the risk factors of ONFH [6,9].…”

“…Likewise, our results showed that in the setting of osteonecrosis, aMSCs showed superior osteogenic potential compared with bmMSCs as measured by alkaline phosphatase activity. This may be explained partly in previous studies showing that patients with corticosteroidinduced and alcohol-induced osteonecrosis have decreased osteogenesis from their bmMSCs [7,9,12,17,34]. Greater physiologic stress in the bone marrow may contribute to the discrepant osteogenesis profile of MSCs based on native tissue source in patients with these insults.…”

“…Reported predictors of failure include size of the necrotic lesion, etiology of the osteonecrosis, and proliferation potential of the bmMSCs based on fibroblast colony-forming units [13,22]. In addition, previous studies have shown that patients with corticosteroid-induced and alcohol-induced osteonecrosis have decreased osteogenesis from their bmMSCs [7,9,12,17,34] and could account for the limited results obtained in certain osteonecrosis groups. Identifying other potential sources of MSCs is of critical importance for management of patients who may be considered at high risk for failure.…”
