Donor Age

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.

Differentiation Potential

Adult human bone marrow stromal cells (hBMSC) are important for many scientific purposes because of their multipotency, availability, and relatively easy handling. They are frequently used to study osteogenesisin vitro. Most commonly, hBMSC are isolated from bone marrow aspirates collected in clinical routine and cultured under the “aspect plastic adherence” without any further selection. Owing to the random donor population, they show a broad heterogeneity. Here, the osteogenic differentiation potential of 531 hBMSC was analyzed. The data were supplied to correlation analysis involving donor age, gender, and body mass index. hBMSC preparations were characterized as follows: (a) how many passages the osteogenic characteristics are stable in and (b) the influence of supplements and culture duration on osteogenic parameters (tissue nonspecific alkaline phosphatase (TNAP), octamer binding transcription factor 4, core-binding factor alpha-1, parathyroid hormone receptor, bone gla protein, and peroxisome proliferator-activated proteinγ). The results show that no strong prediction could be made from donor data to the osteogenic differentiation potential; only the ratio of induced TNAP to endogenous TNAP could be a reliable criterion. The results give evidence that hBMSC cultures are stable until passage 7 without substantial loss of differentiation potential and that established differentiation protocols lead to osteoblast-like cells but not to fully authentic osteoblasts.

Carbonate Apatite

Previous study showed that the novel poly(ε-caprolactone)–organosiloxane nano-hybrid material (SiOPCL) had bioactivity, biodegradability, and mechanical properties comparable to those of human cancellous bone. In this study, hydroxyl carbonate apatite layer (HCA) was preformed on the surface of SiOPCL, which mimicked the events likely to occur in vivo, and cellular behaviors of human bone marrow stromal cells (hBMSCs) were investigated during the osteogenic differentiation on its surface (SiOPCL/HCA). Initial attachment, proliferation, and ALP activities of hBMSCs were comparable to those on tissue culture plates (TCPs), while the calcium content in the cell layer showed significantly higher value. It means that this novel bioactive nano-hybrid material is likely to be a promising candidate for bone grafting materials because of good hBMSCs responses as well as apatite forming ability in the simulated body fluid.
