    Stimulative Effects of Low Intensity He-Ne Laser Irradiation on the Proliferative Potential and Cell-Cycle Progression of Myoblasts in Culture by Cui-Ping Zhang, Shao-Dan Li, Yan Chen, Yan-Ming Jiang, Peng Chen, Chang-Zhen Wang, Xiao-Bing Fu, Hong-Xiang Kang, Ben-Jian Shen, Jie Liang

    Published 2014-01-01
    “…Primary myoblasts isolated from rat hind legs were cultured in nutrient-deficient medium for 36 hours and then irradiated by helium-neon laser at a certain energy density. Immunohistochemical and flow cytometric analysis revealed that laser irradiation could increase the expression of cellular proliferation marker and the amount of cell subpopulations in the proliferative phase as compared with the nonirradiated control group. …”
