Abstract The interaction between multiple myeloma (MM) cells and the bone marrow (BM) microenvironment plays a crucial role not only in proliferation and survival of MM cells, but also in osteoclastogenesis. In this study, we examined diverse potential of novel p38MAPK inhibitor LSN2322600 (LSN) for MM therapy in vitro and in vivo. The cytotoxic activity of LSN against MM cell lines was modest; however, LSN significantly enhances the cytotoxicity of Bortezomib by down-regulating Bortezomib-induced heat shock protein (HSP) 27 phosphorylation. We next examined the effects of LSN on cytokine secretion in MM cells, bone marrow stromal cells and osteoclast precursor cells. LSN inhibited IL-6 secretion from long-term cultured-bone marrow stromal cells (LT-BMSCs) and bone marrow mononuclear cells (BMMNCs) from MM patients in remission. LSN also inhibited MIP-1 α secretion by fresh tumor cells, BMMNCs and CD14 positive cells. Since these cytokines mediate osteoclastogenesis, we further examined whether LSN could inhibit osteoclastogenesis. Importantly, LSN inhibited in vitro osteoclastogenesis induced by macrophage-colony stimulating factor (M-CSF) and soluble receptor activator of nuclear factor- κ B ligand (sRANKL), as well as osteoclastogenesis in the severe combined immunodeficiency (SCID)-Hu mouse model of human MM. These results suggest that LSN represents a promising novel targeted strategy to reduce skeletal complications as well as to sensitize or overcome resistance to Bortezomib.

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.

Secreted Factors

Acute kidney injury is a devastating syndrome that afflicts over 2,000,000 people in the US per year, with an associated mortality of greater than 70% in severe cases. Unfortunately, standard-of-care treatments are not sufficient for modifying the course of disease. Many groups have explored the use of bone marrow stromal cells (BMSCs) for the treatment of AKI because BMSCs have been shown to possess unique anti-inflammatory, cytoprotective, and regenerative propertiesin vitroandin vivo. It is yet unresolved whether the primary mechanisms controlling BMSC therapy in AKI depend on direct cell infusion, or whether BMSC-secreted factors alone are sufficient for mitigating the injury. Here we show that BMSC-secreted factors are capable of providing a survival benefit to rats subjected to cisplatin-induced AKI. We observed that when BMSC-conditioned medium (BMSC-CM) is administered intravenously, it prevents tubular apoptosis and necrosis and ameliorates AKI. In addition, we observed that BMSC-CM causes IL-10 upregulation in treated animals, which is important to animal survival and protection of the kidney. In all, these results demonstrate that BMSC-secreted factors are capable of providing support without cell transplantation, and the IL-10 increase seen in BMSC-CM-treated animals correlates with attenuation of severe AKI.
