Abstract Title:
Photobiomodulation therapy compensate the impairments of diabetic bone marrow mesenchymal stem cells.
Abstract:
Pathophysiologic conditions associated with diabetes mellitus affect mesenchymal stem cells (MSCs), and this phenomenon may lead to some diabetic secondary complications. The present study was conducted to evaluate the impact of photobiomodulation (PBM) on rat diabetic MSC (DMSC) behavior in vitro. For the purpose of PBM, we used helium-neon laser with a wavelength of 632.8 nm at three different energy densities (0.5, 1, 2 J/cm) and radiation periodicity of once, twice, and thrice. The survival, proliferation, and apoptosis in the normal MSCs (NMSCs), DMSCs, and diabetic MSCs, which were laser irradiated (DMSCs+L), were assessed using MTT assay, Ki67 immunofluorescence staining, and TUNEL assay, respectively. Our results demonstrated that DMSCs have significantly lower survival (P
