Adult skeletal muscle can undergo regeneration after damage, thanks to a resident population of stem cells, namely satellite cells, located underneath the basement membrane of the skeletal muscle fibers. However, these cells are scarce in number and, in case of severe and extended muscle damage, they cannot be efficient enough as to promote tissue repair. Recent trends in the field of regenerative medicine are attempting to identify novel strategies aimed to improve the endogenous tissue repair potential and contribute to the recreation of a less hostile microenvironment for muscle cell progenitors functionality. In such perspective, platelet rich plasma (PRP) appears to be provided with several desirable properties for regenerative purposes, representing a source of multiple growth factors, as well as an optimal substitute for animal serum. On these bases, in this study we evaluated the effect of PRP on C2C12 myoblasts in terms of viability, proliferation and myogenic differentiative potential. It was found that PRP, used at different concentrations, was able to positively influence C2C12 cell viability and proliferation as observed by MTS assay, EdU incorporation and confocal immunofluorescence analysis of Ki67 expression. The differentiative potential of C2C12 myoblasts treated with PRP was investigated by confocal immunofluorescence analysis of the expression of specific markers.

Abstract
Adult skeletal muscle can undergo regeneration after damage, thanks to a resident population of stem cells, namely satellite cells, located underneath the basement membrane of the skeletal muscle fibers. However, these cells are scarce in number and, in case of severe and extended muscle damage, they cannot be efficient enough as to promote tissue repair. Recent trends in the field of regenerative medicine are attempting to identify novel strategies aimed to improve the endogenous tissue repair potential and contribute to the recreation of a less hostile microenvironment for muscle cell progenitors functionality. In such perspective, platelet rich plasma (PRP) appears to be provided with several desirable properties for regenerative purposes, representing a source of multiple growth factors, as well as an optimal substitute for animal serum. On these bases, in this study we evaluated the effect of PRP on C2C12 myoblasts in terms of viability, proliferation and myogenic differentiative potential. It was found that PRP, used at different concentrations, was able to positively influence C2C12 cell viability and proliferation as observed by MTS assay, EdU incorporation and confocal immunofluorescence analysis of Ki67 expression. The differentiative potential of C2C12 myoblasts treated with PRP was investigated by confocal immunofluorescence analysis of the expression of specific markers. In conclusion, our preliminary data suggest that PRP may play a pivotal role in skeletal muscle regeneration and can be considered as a valuable tool in designing therapeutic protocols in the field of regenerative medicine.File | Dimensione | Formato | |
