Muscle on a Chip: State of the Art
Why a muscle on a chip?
FUN FACT: Skeletal muscles account for 40% of the total body weight in humans and consume about 30% of energy intake.
Skeletal muscles are also called striated muscle. Excessive loss of muscle mass often come with chronic pathologies, aggravating the general condition of the patient, which can result in cachexia. Most musculoskeletal disorders do not have a curative treatment yet. Some diseases such as amyotrophic lateral sclerosis, Duchenne’s disease or Lou Gehrig’s disease still do not have an effective treatment.
In parallel, some treatments of chronic diseases (diabetes, cholesterol) have undesirable effects on the striated muscles. Having access to a muscle on a chip would investigate the occurrence of such adverse effects and a better prediction of the effects of a drug candidate during the clinical phase.
