Pulmonary artery smooth muscle cell (PASMC) adhesion, spreading, and migration depend on matrix-stimulated reorganization of focal adhesions. Platelet-derived growth factor (PDGF) activates intracellular signal transduction cascades that also regulate adhesion, spreading, and migration, but the signaling molecules involved in these events are poorly(More)
We recently reported that skeletal muscle fibers of obscurin knockout (KO) mice present altered distribution of ankyrin B (ankB), disorganization of the subsarcolemmal microtubules, and reduced localization of dystrophin at costameres. In addition, these mice have impaired running endurance and increased exercise-induced sarcolemmal damage compared with(More)
Cardiac c-kit(+) cells are generally believed to be the major population of stem/progenitor cells in the heart and can be used as a cell source for cardiomyoplasty; however, the cellular electrophysiological properties are not understood in this type of cells. The present study was designed to investigate functional ion channels in undifferentiated mouse(More)
