AbstractSenile osteoporosis can cause bone fragility and increased fracture risks and has been one of the most prevalent and severe diseases affecting the elderly population. Bone formation depends on the proper osteogenic differentiation of bone marrow stromal cells (BMSCs) in the bone marrow microenvironment, which is generated by the functional relationship among different cell types in the bone marrow. With aging, bone marrow provides signals that repress osteogenesis. Finding the signals that oppose BMSC osteogenic differentiation from the bone marrow microenvironment and identifying the abnormal changes in BMSCs with aging are key to elucidating the mechanisms of senile osteoporosis. In a pilot experiment, we found that 4-1BBL and 4-1BB were more abundant in bone marrow from aged (18-month-old) mice than young (6-month-old) mice. Meanwhile, significant bone loss was observed in aged mice compared with young mice. However, very little data have been generated regarding whether high-level 4-1BB/4-1BBL in bone marrow was associated with bone loss in aged mice. In the current study, we found upregulation of 4-1BB in the BMSCs of aged mice, which resulted in the attenuation of the osteogenic differentiation potential of BMSCs from aged mice via the p38 MAPK-Dkk1 pathway. More importantly, bone loss of aged mice could be rescued through the blockade of 4-1BB signaling in vivo. Our study will benefit not only our understanding of the pathogenesis of age-related trabecular bone loss but also the search for new targets to treat senile osteoporosis.

The relationships between donor age and gender and initial isolation yield and the osteogenic potentials of human bone marrow stromal cells (hBMSCs) have not been clearly elucidated. The authors investigated whether isolation yields and the osteogenic differentiation potentials of hBMSCs are indeed dependent on donor age or gender. Fresh bone marrow was aspirated from iliac crest of 72 donors (mean age 54.1 years; range, 23-84 years; 39 men and 33 women) undergoing total hip arthroplasty. Numbers of mononuclear cells, numbers of colony forming unit-fibroblasts (CFU-Fs) and alkaline phosphatase (ALP)-positive CFU-Fs, and numbers of BMSCs after isolation culture were not found to be significantly dependent on donor age or gender. Moreover, no significant age- or gender-related differences were observed in terms of the proliferation activities, ALP activities, and calcium contents of BMSCs during in vitro osteogenic differentiation. The data obtained from 72 human donors revealed no significant age- or genderrelated differences among hBMSCs in terms of isolation yields, proliferation activities, and osteogenic potentials.
