"title := \\\"ATP regulates the differentiation of mammalian skeletal muscle by activation of a P2X5 receptor on satellite cells.\\\" Using immunocytochemistry, RT-PCR, and electrophysiology, we demonstrate that the ionotropic P2X5 receptor is present on satellite cells and that activation of a P2X receptor inhibits proliferation, stimulates expression of markers of muscle cell differentiation, including myogenin, p21, and myosin heavy chain, and increases the rate of myotube formation." . .
