Mitochondria are cell organelles surrounded by a double membrane. In addition to numerous essential functions in the ...
Researchers at Karolinska Institutet have discovered a previously unknown molecule that may explain why people with type 2 diabetes often suffer from muscle weakness and muscle loss—a condition that ...
Scientists have developed a technique that aligns stem cells into a single sheet, resulting in a marked increase in the secretion of signaling proteins which help repair tissue and regulate the immune ...
Eukaryotic cells form the foundation of complex life, their defining feature being the presence of membrane-bound organelles. This article details the structure of eukaryotic cells and provides ...
A “biohybrid” robotic hand built using real human muscle cells A real bit of cyborg hardware highlights the technology's current limitations.
In muscle cells, the ER and the plasma membrane—the outer membrane of the cell—meet at periodic contact sites, an arrangement controlled by a molecule called junctophilin.
New research reveals that brain cells use a muscle-like signaling mechanism to relay information over long distances.
In this article, we discuss the structure and function of cardiac muscle tissue. We also cover medical conditions that can affect this muscle tissue and tips for keeping it healthy.
If you're one of the 13% of American adults who has taken a GLP-1 drug for weight loss, you may know that while fat seemingly melts away, so too does muscle. And if you're not one for weights, or ...
Conditions such as long COVID-19, Alzheimer’s disease and meningitis can damage the line of communication between your brain and your muscles.
