Large-scale gene expression profiling data of bone marrow stromal cells from osteoarthritic donors.

This data article contains data related to the research article entitled, "in vitro characterization of bone marrow stromal cells from osteoarthritic donors" [1]. Osteoarthritis (OA) represents the main indication for total joint arthroplasty and is one of the most frequent degenerative joint disorders. However, the exact etiology of OA remains unknown.

In vitro characterization of bone marrow stromal cells from osteoarthritic donors.

BMSCs, also known as bone marrow-derived mesenchymal stem cells, provide an excellent source of progenitor cells for regenerative therapy. To assess whether osteoarthritis (OA) affects the regenerative potential of BMSCs we compared the proliferation and differentiation potential as well as the surface marker expression profile of OA- versus control BMSCs. BMSCs were isolated from bone marrow aspirates of n=14 patients with advanced-stage idiopathic hip OA (67±6years) and n=15 healthy individuals (61±4years).

Perivascular Mesenchymal Stem Cells From the Adult Human Brain Harbor No Instrinsic Neuroectodermal but High Mesodermal Differentiation Potential.

Unlabelled: Brain perivascular cells have recently been identified as a novel mesodermal cell type in the human brain. These cells reside in the perivascular niche and were shown to have mesodermal and, to a lesser extent, tissue-specific differentiation potential. Mesenchymal stem cells (MSCs) are widely proposed for use in cell therapy in many neurological disorders; therefore, it is of importance to better understand the "intrinsic" MSC population of the human brain.

Identification of stable reference genes for gene expression analysis of three-dimensional cultivated human bone marrow-derived mesenchymal stromal cells for bone tissue engineering.

The principles of tissue engineering (TE) are widely used for bone regeneration concepts. Three-dimensional (3D) cultivation of autologous human mesenchymal stromal cells (MSCs) on porous scaffolds is the basic prerequisite to generate newly formed bone tissue. Quantitative reverse transcription polymerase chain reaction (qRT-PCR) is a specific and sensitive analytical tool for the measurement of mRNA-levels in cells or tissues.

Comparative biomechanical and microstructural analysis of native versus peracetic acid-ethanol treated cancellous bone graft.

Bone transplantation is frequently used for the treatment of large osseous defects. The availability of autologous bone grafts as the current biological gold standard is limited and there is a risk of donor site morbidity. Allogenic bone grafts are an appealing alternative, but disinfection should be considered to reduce transmission of infection disorders.

Identification of suitable reference genes in bone marrow stromal cells from osteoarthritic donors.

Bone marrow stromal cells (BMSCs) are key cellular components for musculoskeletal tissue engineering strategies. Furthermore, recent data suggest that BMSCs are involved in the development of Osteoarthritis (OA) being a frequently occurring degenerative joint disease. Reliable reference genes for the molecular evaluation of BMSCs derived from donors exhibiting OA as a primary co-morbidity have not been reported on yet.

Comparative analysis of reference gene stability in human mesenchymal stromal cells during osteogenic differentiation.

Mesenchymal stromal cells (MSCs) are one of the most frequently used cell sources for tissue engineering strategies. Cultivation of osteogenic MSCs is a prerequisite for cell-based concepts that aim at bone regeneration. Quantitative real time reverse transcription polymerase chain reaction (qRT-PCR) analysis is a commonly used method for the examination of mRNA expression levels.

Bioreactor systems for bone tissue engineering.

Bone graft material is often required for the treatment of osseous defects. However, due to limitations and risks associated with autologous as well as allogenic bone grafting procedures, alternative strategies are needed. In this context, ex vivo tissue engineering (TE) strategies for de novo generation of bone tissue include the combined use of autologous bone-forming cells and three-dimensional (3D) porous scaffold materials serving as structural support for the cells.

Cancellous bone allograft seeded with human mesenchymal stromal cells: a potential good manufacturing practice-grade tool for the regeneration of bone defects.

Background Aims: Combining autologous bone precursor cells with cancellous bone allograft (CBA) offers an appealing strategy for skeletal regeneration. In this context, multipotent mesenchymal stromal cells (MSC) provide an excellent cell source because they are readily harvested from donors, expanded and differentiated in vitro. The aim of this study was to evaluate the proliferation, morphology, osteogenic differentiation and stem cell-related gene expression during static long-term ex vivo cultivation using human MSC and CBA under good manufacturing practice (GMP)-conforming conditions.
