A growing need for tissues and organs in surgical reconstruction is addressed by the promising field of tissue engineering. For instance, muscle atrophy results from severe traumatic events including deep burns and cancer, ...
A research group led by Clemson University has developed a strategy to improve heart repair using human pluripotent stem cell–derived cardiomyocytes combined with biodegradable and biocompatible electroconductive silicon ...
UCLA scientists have developed a new strategy to efficiently isolate, mature and transplant skeletal muscle cells created from human pluripotent stem cells, which can produce all cell types of the body. The findings are a ...

(Medical Xpress)—Industrial robots can do incredible things, but their control systems are still incredibly complex. They rely largely on rotary electric power that is feedback-controlled, usually through precision optical ...
(Medical Xpress)—Blood transfusions are supposed to save lives. Doctors give transfusions to severely ill or injured people with the expectation that their conditions will improve. In fact, transfusions do not always help ...
(Medical Xpress)—Membrane fusion is a highly regulated event, both inside cells, and between them. From the moment a sperm first fuses with an egg, subsequent developmental events depend upon its proper control. Inside ...
Researchers from University of Tsukuba have elucidated the molecular mechanism by which macrophages, a type of immune cell, control heat production in brown adipose tissue to increase the body temperature in response to cold.

Skeletal muscle is a form of striated muscle tissue existing under control of the somatic nervous system. It is one of three major muscle types, the others being cardiac and smooth muscle. As its name suggests, skeletal muscle is linked to bone by bundles of collagen fibers known as tendons.
Skeletal muscle is made up of individual components known as muscle fibers. These fibers are long, cylindrical, multinucleated cells composed of actin and myosin myofibrils repeated as a sarcomere, the basic functional unit of the cell and responsible for skeletal muscle's striated appearance and forming the basic machinery necessary for muscle contraction. The term muscle refers to multiple bundles of muscle fibers held together by connective tissue.
