Evaluation of autologous skeletal muscle-derived factors for regenerative medicine applications

چکیده
OBJECTIVES Regenerative medicine is an emerging field aimed at the repair and regeneration of various tissues. To this end, cytokines (CKs), growth factors (GFs), and stem/progenitor cells have been applied in this field. However, obtaining and preparing these candidates requires invasive, costly, and time-consuming procedures. We hypothesised that skeletal muscle could be a favorable candidate tissue for the concept of a point-of-care approach. The purpose of this study was to characterize and confirm the biological potential of skeletal muscle supernatant for use in regenerative medicine. METHODS Semitendinosus muscle was used after harvesting tendon from patients who underwent anterior cruciate ligament reconstructions. A total of 500 milligrams of stripped muscle was minced and mixed with 1 mL of saline. The collected supernatant was analysed by enzyme-linked immunosorbent assay (ELISA) and flow cytometry. The biological effects of the supernatant on cell proliferation, osteogenesis, and angiogenesis in vitro were evaluated using human mesenchymal stem cells (hMSCs) and human umbilical cord vein endothelial cells (HUVECs). RESULTS The supernatant contained several GFs/CKs, with especially high levels of basic fibroblast growth factor, and CD34+ cells as the stem/progenitor cell fraction. With regard to biological potential, we confirmed that cell proliferation, osteoinduction, and angiogenesis in hMSCs and HUVECs were enhanced by the supernatant. CONCLUSIONS The current study demonstrates the potential of a new point-of-care strategy for regenerative medicine using skeletal muscle supernatant. This attractive approach and readily-available material could be a promising option for tissue repair/regeneration in the clinical setting.Cite this article: M. Yoshikawa, T. Nakasa, M. Ishikawa, N.

Mammalian skeletal muscle has a significant capacity for regeneration following injury; however, loss of approximately 20% or more of the mass of an individual muscle (or muscle group) is termed volumetric muscle loss (VML). Consequences of VML include extensive scar tissue deposition, loss of function, and significant morbidity. Almost all therapeutic approaches have involved surgery (e.g., au...
متن کاملApplications of Small Molecules in Muscle Tissue Engineering
Introduction: Skeletal muscles account for about 40% of the total body weight. Every year, hundreds of people lose at least part of their muscle tissue due to illness, war, and accidents. This can lead to disruption of activities such as breathing, movement, and social life. To this end, various therapeutic strategies such as medication therapy, cell therapy and tissue transplantation have been...
متن کاملAdipose tissue as a stem cell source for musculoskeletal regeneration.
Adipose tissue is an abundant, easily accessible, and reproducible cell source for musculo-skeletal regenerative medicine applications. Initial derivation steps yield a heterogeneous population of cells of stromal vascular fraction (SVF) cells. Subsequent adherent selection of the SVF results in a relatively homogeneous population of adipose-derived stromal/stem cells (ASCs) capable of adipogen...

The limitation in successfully acquiring large populations of stem cell has impeded their application. A new method based on the dedifferentiation of adult somatic cells to generate induced multipotent stem cells would allow us to obtain a large amount of autologous stem cells for regenerative medicine. The current work was proposed to induce a sub-population of cells with characteristics of mu...
متن کاملPotential of adipose-derived stem cells in muscular regenerative therapies
Regenerative capacity of skeletal muscles resides in satellite cells, a self-renewing population of muscle cells. Several studies are investigating epigenetic mechanisms that control myogenic proliferation and differentiation to find new approaches that could boost regeneration of endogenous myogenic progenitor populations. In recent years, a lot of effort has been applied to purify, expand and...
