“…Among quantified lipids, SEA and PGE2 showed a relevant uniformity that was therefore validated in a larger ASC-CM cohort. SEA is an endogenous lipid belonging to the N-acylethanolamides family that acts as an anti-inflammatory/immunomodulatory agent through the downregulation of several proinflammatory cytokines [ 37 ]. Conversely, PGE2 exerts a well-known inflammatory action.…”

The therapeutic potential of the conditioned medium (CM) derived from MSCs (mesenchymal stem/stromal cells) in disparate medical fields, from immunology to orthopedics, has been widely suggested by in vitro and in vivo evidences. Prior to MSC-CM use in clinical applications, appropriate quality controls are needed in order to assess its reproducibility. Here, we evaluated different CM characteristics, including general features and precise protein and lipid concentrations, in 3 representative samples from adipose-derived MSCs (ASCs). In details, we first investigated the size and distribution of the contained extracellular vesicles (EVs), lipid bilayer-delimited particles whose pivotal role in intercellular communication has been extensively demonstrated. Then, we acquired Raman signatures, providing an overlook of ASC-CM composition in terms of proteins, lipids, and nucleic acids. At last, we analyzed a panel of 200 molecules including chemokines, cytokines, receptors, and inflammatory and growth factors and searched for 32 lipids involved in cell signalling and inflammation. All ASC-CM contained a homogeneous and relevant number of EVs ( 1.0 × 10 9 ± 1.1 × 10 8 particles per million donor ASCs) with a mean size of 190 ± 5.2 nm , suggesting the appropriateness of the method for EV retaining and concentration. Furthermore, also Raman spectra confirmed a high homogeneity among samples, allowing the visualization of specific peaks for nucleic acids, proteins, and lipids. An in depth investigation that focused on 200 proteins involved in relevant biological pathways revealed the presence in all specimens of 104 factors. Of these, 26 analytes presented a high degree of uniformity, suggesting that the samples were particularly homogenous for a quarter of the quantified molecules. At last, lipidomic analysis allowed the quantification of 7 lipids and indicated prostaglandin-E2 and N-stearoylethanolamide as the most homogenous factors. In this study, we assessed that ASC-CM samples obtained with a standardized protocol present stable features spanning from Raman fingerprint to specific marker concentrations. In conclusion, we identified key ingredients that may be involved in ASC-CM therapeutic action and whose consistent levels may represent a promising quality control in the pipeline of its preparation for clinical applications.

“…Nevertheless, in the OA context, it can exert either anabolic or catabolic effects on chondrocytes and synoviocytes depending on its concentration [ 38 – 40 ]. Evidence suggests also that PGE2 may have an immune stimulatory role by facilitating Th1 differentiation and expanding Th17 T cells [ 37 ].…”

Introduction -Elderly is a time when a person will experience a decrease in body functions both physically, mentally and socially. One of the physical declines felt by the elderly is the decline in joint movement. The reduced elasticity of the joints will make stiffness in the joints resulting in joint pain. Range of motion (ROM) is one of the activities that can be used to relieve joint pain.Purpose -The purpose of this study was to determine the effect of joint motion exercises (ROM) on joint pain felt in the elderly.Methodology/Approach -This study used a quasi-experimental pre-post-test in the treatment group and the control group. The number of subjects was 52 people with 26 people in the treatment group and 26 people in the control group. The treatment group was given joint motion exercises 3x/week for 6 weeks. The statistical test in the treatment group used the paired sample T-Test, the control group used the Wilcoxon signed rank test and for the comparison test, the Mann Whitney test was used.Results -The results of the study in the treatment group showed that ROM had an effect on reducing joint pain in the elderly (p = 0.001), in the control group there was no significant change (p = 0.265) There was a difference in the effect of reducing joint pain in the treatment group and the control group (p = 0.001).Conclusion -ROM exercises can decrease joint pain in the elderly. .

“…The involvement of these bioactive lipids in the mesenchymal stem/stromal cells (MSC)-related inflammatory context was recently reviewed. 5 MSC are non-hematopoietic multipotent progenitor cells located in the perivascular area of most vessels throughout the body. Over the years, MSC have gained popularity as therapeutics in a variety of clinical scenarios thanks to their ability to promote tissue regeneration and reduce inflammation.…”

Analytical advancements in lipidomics have enabled large-scale investigations of lipid biology. Herein, we focused on four bioactive lipid families, namely polyunsaturated fatty acids, eicosanoids, endocannabinoids, and N-acylethanolamines, and their involvement in the mesenchymal stem cells (MSC)-related inflammatory scenario. Since MSC secretome may represent a valid therapeutic alternative, here, the complete secretome and its vesicular component from adipose- and bone marrow-derived MSC and dermal fibroblasts were characterized by targeted mass spectrometry lipidomics. The 2-arachidonoylglycerol (2AG) and the palmitoylethanolamide (PEA), previously quantified in the MSC’s secretome, were further investigated by assessing hypothetical effects in an in vitro model of osteoarthritis (OA) based on human primary articular chondrocytes (CH) stimulated with tumor necrosis factor alpha (TNFα). TNFα enhances the release of the inflammatory lipid prostaglandin E2 (PGE2), and an additional increment was observed when CH were treated with both TNFα and 2AG. In contrast, PEA downmodulates the PGE2 release to the levels of unstimulated CH suggesting a protective effect. TNFα also increases the expression of cyclooxygenase 2 (COX2), in particular when combined with 2AG, while PEA partly blunts TNFα-induced COX2 expression. In addition, TNFα-stimulated CH produce significantly higher levels of the inflammatory mediator nitric oxide (NO) both in the presence and in the absence of 2AG, and PEA was able to partially reduce NO release. Our results show a first partial lipidomic profile of MSC and DF secretome and suggest a possible implication of bioactive lipids in the OA scenario and in the future use of these cell-free products as innovative therapeutics.
