Stem Cell Treatment and Osteoarthritis at SIRM
What is Osteoarthritis ?
Symptoms may include joint pain, tenderness, stiffness, locking, and sometimes an effusion. A variety of causes include hereditary, developmental, metabolic, and mechanical. OA may initiate processes leading to the loss of cartilage.
When bone surfaces become less well protected by cartilage, bone may be exposed and damaged. As a result of decreased movement secondary to pain, regional muscles may atrophy, and ligaments may become more lax.

Mesenchymal stem cells (MSCs) have been proposed to be a useful tool for treatment of rheumatoid arthritis (RA), not only because of their multipotency but also because of their immunosuppressive effect on lymphocytes, dendritic cells, and other proinflammatory cells.
Since bone destruction caused by activated osteoclasts occurs in RA, we undertook the present study to investigate the effect of MSCs on osteoclast function and differentiation in order to evaluate their potential use in RA therapy.

Prospects of stem cell therapy in osteoarthritis.

Osteoarthritis is a common disorder in which there is not only extensive degeneration but also an aberrant attempt at repair in joints.
Stem cell therapy could provide a permanent, biological solution, with all sources of stem cells (embryonic, fetal and adult) showing some degree of potential.
Mesenchymal stromal/stem cells, however, appear to be the leading candidates because of their ability to be sourced from many or all joint tissues. They may also modulate the immune response of individuals, in a manner influenced by local factors.
This biological behavior of stem cells renders the application of regulatory standardizations challenging in comparison to pharmaceutical therapies. However, this would not be an issue if endogenous stem cells were activated to effect repair of an arthritic joint.
Mesenchymal stem cell therapy for knee osteoarthritis. Preliminary report of four patients.

Background: Osteoarthritis (OA) is a cartilage degenerative process, involving the immune system, producing local inflammatory reactions, with production of pro-inflammatory cytokines and metalloproteinases. No treatment is still available to improve or reverse the process. Stem cell therapy opened new horizons for treatment of many incurable diseases.
Mesenchymal stem cells (MSCs) due to their multi-lineage potential, immunosuppressive activities, limited immunogenicity and relative ease of growth in culture, have attracted attentions for clinical use. Aim: The aim of this study was to examine whether MSC transplantation could reverse the OA process in the knee joint.
The project was approved by the Tehran University of Medical Sciences Research Committee and Ethical Committee. Patients and Methods: Four patients with knee osteoarthritis were selected for the study. They were aged 55, 57, 65 and 54 years, and had moderate to severe knee OA. After their signed written consent, 30 mL of bone marrow were taken and cultured for MSC growth.
After having enough MSCs in culture (4-5 weeks) and taking in consideration all safety measures, cells were injected in one knee of each patient. Results: The walking time for the pain to appear improved for three patients and remained unchanged for one. The number of stairs they could climb and the pain on visual analog scale improved for all of them. On physical examination, the improvement was mainly for crepitus.
It was minor for the improvement of the range of motion. Conclusion: Results were encouraging, but not excellent. Improvement of the technique may improve the results.
Telomere length, telomerase activity and osteogenic differentiation are maintained in adipose-derived stromal cells from senile osteoporotic SAMP6 mice.

Adipose tissue provides for a rich and easily accessible source of multipotent stromal cells and thus offers the potential for autologous cell-based therapy for a number of degenerative diseases. Senile osteoporosis is characterized by a reduction in bone quality, which is associated with inadequacies in bone marrow stromal cell (BMSC) differentiation. In the present study, we have characterized adipose-derived stromal cells (ASCs) isolated from aged osteoporotic mice and evaluated their suitability as a source of osteogenic precursor cells.
Significant reductions in both tibia bone quality and telomere length in liver tissue were observed in the senescence-accelerated mouse prone 6 strain (SAMP6), as compared to the control age-matched senescence-accelerated mouse resistant 1 strain (SAMR1), thus confirming osteoporosis and accelerated ageing traits in this model.
ASCs isolated from inguinal fat expressed mesenchymal surface markers and were capable of differentiating along the osteoblast, adipocyte and chondrocyte lineages. Telomere length was not compromised in ASCs from SAMP6 mice but was actually found to be significantly increased as compared to control SAMR1 mice.
Furthermore, ASCs from both strains were comparable in terms of telomerase activity, p21 mRNA expression, SA-β-gal activity and proliferative capacity. The overall osteogenic and adipogenic potential of ASCs was comparable between SAMP6 and SAMR1 strains, as determined by quantitative molecular, biochemical and histological analyses.
In conclusion, adipose tissue may represent a promising autologous cell source for the development of novel bone regenerative therapeutic strategies in the treatment of age-related osteoporosis. Copyright © 2011 John Wiley & Sons, Ltd.

METHODS: The burden of musculoskeletal disorders was calculated for the EMR's 22 countries between 1990 and 2013. A systematic analysis was performed on mortality and morbidity data to estimate prevalence, death, years of live lost, years lived with disability and disability-adjusted life years (DALYs). RESULTS: For musculoskeletal disorders, the crude DALYs rate per 100 000 increased from 1297.1 (95% uncertainty interval (UI) 924.3-1703.4) in 1990 to 1606.0 (95% UI 1141.2-2130.4) in 2013. During 1990-2013, the total DALYs of musculoskeletal disorders increased by 105.2% in the EMR compared with a 58.0% increase in the rest of the world. The burden of musculoskeletal disorders as a proportion of total DALYs increased from 2.4% (95% UI 1.7-3.0) in 1990 to 4.7% (95% UI 3.6-5.8) in 2013. The range of point prevalence (per 1000) among the EMR countries was 28.2-136.0 for low back pain, 27.3-49.7 for neck pain, 9.7-37.3 for osteoarthritis (OA), 0.6-2.2 for rheumatoid arthritis and 0.1-0.8 for gout. Low back pain and neck pain had the highest burden in EMR countries. CONCLUSIONS: This study shows a high burden of musculoskeletal disorders, with a faster increase in EMR compared with the rest of the world. The reasons for this faster increase need to be explored. Our findings call for incorporating prevention and control programmes that should include improving health data, addressing risk factors, providing evidence-based care and community programmes to increase awareness.
