Main body:The notion that lifelong regeneration of the muscle is dependent on a rare, non-redundant population of stem cells seems contradictory to accumulating evidence that muscle stem cells have activated multiple stress response pathways. For example, muscle stem cell quiescence is mediated in ...
Multi-organ single-cell transcriptomics of immune cells uncovered organ-specific gene expression and functions Maria Tsagiopoulou Sonal Rashmi Ivo G.

摘要: I was asked to comment about a new technique that I've been developing that allows analysis of very small samples of fluid from muscle cells. I'm trying to estimate the elemental composition of muscle fluid, as close to the in vivo condition as possible....
The nature of the contractile stimuli to which a skeletal muscle is subjected determines which proteins will increase in skeletal muscle. Rates of muscle protein synthesis decrease during an exercise bout for durations of less than 30 min. Synthesis has been reported to increase, remain unchanged, ...
Mammal - Adaptations, Physiology, Reproduction: The skin is constructed of two layers, the epidermis and the dermis. Most mammals have three distinct kinds of hair: guard hairs, underfur, and whiskers. Other anatomical features derived from the integumen
The aim of this report is to elucidate the effects of exercise training on metabolic properties of different muscle fibre types of the rat hindlimb. Single... H Takekura,T Yoshioka - 《Journal of Muscle Research & Cell Motility》 被引量: 38发表: 1990年 Effect of constant load training on...
In most electric fish species, the electric organ (EO) derives from striated muscle cells that suppress many muscle properties. In the gymnotiform Sternopygus macrurus, electrocytes, the current-producing cells of the EO, derive from type II (fast-twitch) muscle fibers during tail regeneration...
The simplest situation is seen in the epidermis, but even here there is a layered system in which different cell types provide different functions (such as protection and secretion). The stratified epithelium of the vertebrate is highly characteristic of that group (a similar one is seen in ...
How is it possible for a plant to survive that long without water? Garden plants start wilting if they don't get rain every week. A normal plant growing in a place with adequate rainfall has a constant flow of water going in through its roots, up through its stems, and out through ...
Organisms have evolved a range of phenotypic and genetic adaptations to live in different environments along an altitudinal gradient. Herein, we studied the widely distributed Chinese toad, Bufo gargarizans, as a model and used an integrated phenotype-ge
