Last year, we edited a special issue focusing on advances in muscle physiology and pathophysiology that was welcomed by a number of scientists nationally and internationally, who contributed original and review articles on diverse aspects of muscle assembly, structure, and function during normalcy and disease. As new technological developments take place, sophisticated animal models are generated, and high-throughput genomic and proteomic approaches are enlisted, a plethora of novel and exciting information concerning muscle structure and function has already appeared. This year's edition of the special issue will emphasize the most recent advances in muscle physiology and pathophysiology.

We invite authors to present original research articles as well as review articles that will further our current understanding of muscle assembly, organization, and contractility. Potential topics include, but are not limited to:

• Muscle cytoskeleton
• Ca²⁺ regulation
• Stress and stretch sensors
• Stem cells, tissue engineering ,and regenerative medicine
• Disease models

Before submission authors should carefully read over the journal's Author Guidelines, which are located at http://www.hindawi.com/journals/jbb/guidelines/. Prospective authors should submit an electronic copy of their complete manuscript through the journal Manuscript Tracking System at http://mts.hindawi.com/ according to the following timetable:
