Cartilage regeneration by autologous adipose-derived mesenchymal stem cells for the treatment of osteoarthritis

ConclusionHere we show that in twelve clinical cases, the cartilage was observed successfully regenerating and covering the defect region in knees after the intra-articular injection with adipose-derived mesenchymal stem cells (MSCs), and the treatment highly improves the symptoms of osteoarthritis. Basically, the adipose-derived MSCs from the patients are cultured and expanded to a specific amount with the optimized stem cell culture medium, the HELENE MEDIUM. After that, the cultured MSCs are directly injected into the injured knee joints of patients. The cartilage has gradually regenerated and been monitored by MRI photography in six months after treatment. Moreover, these patients showed improvement in clinical outcomes by measurements of the WOMAC Osteoarthritis index and Harris Hip Score. Based on the preclinical and clinical reports, except for replacement as chondrocytes, MSCs are able to secrete paracrine factors which take effects in modulating the microenvironment of the damaged sites, leading to an optimal condition for tissue regeneration. Also, further research will focus on determining co-injection of MSCs with differential factors could facilitate the cartilage regeneration. In summary, our results demonstrate the success in MSCs treatment of osteoarthritis by cartilage regeneration in clinical cases. We expect our findings of MSCs for osteoarthritis treatment could be a starting point in the field of regenerative therapy to more cartilage diseases and unsolve...

In this study, we found that senescent chondrocytes isolated from OA patients secrete more EVs compared with nonsenescent chondrocytes. These EVs inhibit cartilage ECM deposition by healthy chondrocytes and can induce a senescent state in nearby cells. We profiled the miR and protein content of EVs isolated from the synovial fluid of OA joints from mice with SnCs. After treatment with a molecule to remove SnCs, termed a senolytic, the composition of EV-associated miR and protein was markedly altered. The senolytic reduced OA development and enhanced chondrogenesis, and these were attributable to several specific differenti...

In conclusion, long-term aerobic exercise appears to attenuate the decline in endothelial vascular function, a benefit which is maintained during chronological aging. However, currently there is not enough evidence to suggest that exercise interventions improve vascular function in previously sedentary healthy older adults.

Publication date: Available online 7 September 2018Source: PM&RAuthor(s): Paul S. Chirichella, Steven Jow, Stephen Iacono, Hannah E. Wey, Gerard A. MalangaAbstractThe meniscal tear treatment paradigm traditionally begins with conservative measures such as physical therapy with referral for operative management for persistent or mechanical symptoms. As a result, the partial meniscectomy is performed more than any other orthopedic procedure in the United States. This treatment paradigm has shifted as recent literature supports the attempt to preserve or repair the meniscus whenever possible given its importance for the struc...

This study indicates that frailty and other age-related diseases could be prevented and significantly reduced in older adults. Getting our heart risk factors under control could lead to much healthier old ages. Unfortunately, the current obesity epidemic is moving the older population in the wrong direction, however our study underlines how even small reductions in risk are worthwhile." The study analysed data from more than 421,000 people aged 60-69 in both GP medical records and in the UK Biobank research study. Participants were followed up over ten years. The researchers analysed six factors that could impa...

This study demonstrates that small peptide domains derived from native protein amelogenin can be utilized to construct a mineral layer on damaged human enamel in vitro. Six groups were prepared to carry out remineralization on artificially created lesions on enamel: (1) no treatment, (2) Ca2+ and PO43- only, (3) 1100 ppm fluoride (F), (4) 20 000 ppm F, (5) 1100 ppm F and peptide, and (6) peptide alone. While the 1100 ppm F sample (indicative of common F content of toothpaste for homecare) did not deliver F to the thinly deposited mineral layer, high F test sample (indicative of clinical varnish treatment) formed mainly C...

One of the highlights of my trip to Tanzania in 2012 was visiting the Ngorongoro Crater and Conservation Area. They have the largest lions on the planet. I got very close as part of my invitation by the director of park services. Along with elephants, lions, gazelles and zebras, I got to see wildebeest, the almost-extinct black rhino and giraffes. I was lucky enough to photograph this giraffe on my trip to Ngorongoro Crater in Tanzania. I am always awed when I see these magnificent creatures in their native environment. They thrive the same way they did thousands of years ago. But when these animals are tak...

This study didn't measure whether receiving the cardiosphere-derived cells extended lifespans, so we have a lot more work to do. We have much to study, including whether CDCs need to come from a young donor to have the same rejuvenating effects and whether the extracellular vesicles are able to reproduce all the rejuvenating effects we detect with CDCs." Cardiac and systemic rejuvenation after cardiosphere-derived cell therapy in senescent rats Cardiosphere-derived cell (CDC) therapy has exhibited several favourable effects on heart structure and function in humans and in preclinical models; however,...

In conclusion, documentation is important, a critical part of advocacy and the development process at the larger scale. It isn't just words, but rather a vital structural flow of information from one part of the larger community to another, necessary to sustain progress in any complex field. We would all do well to remember this - and to see that building this documentation is an activity in which we can all pitch in to help.
