Each smooth muscle cell is surrounded by an external lamina to which cell membranes adhere; small groups of cells are organized into bundles by fine collagenous tissue containing blood vessels and nerves. Contr
Smooth muscle contains interdigitating thick and thin filaments, but their order is not nearly as precise as exists in striated muscle, giving rise to a ‘smooth’ versus striated appearance in the light microscope. The difference in microscopic appearance between smooth muscle and skeletal muscle ...
Under microscope, they have similar striation as skeletal muscle Cardiac muscle cellsare closely packed but each cell are nucleated and separated from each other The cells are joined end to end by the specialised cell junctions calledintercalated disksthat attach one cell to another withdesmosomes,co...
A thickened smooth muscle layer was observed under a light microscope and an ultrastructure of hypertrophic SMCs, with increased caveolae and decreased dense bodies, was observed under transmission electron microscope. Furthermore, the mRNA and protein expression levels of contractile markers (myosin ...
We next investigated the impact of AMPK-α1/α2 deletion on voltage-gated potassium (KV) currents in acutely isolated pulmonary arterial smooth muscle cells, because reduced activity and/or expression of KV1.5 has been identified as a hallmark of persistent pulmonary hypertension in neonates52,53an...
The aim of our study was to develop a novel approach to investigating mouse detrusor smooth muscle cell (SMC) physiological activity, utilizing an acute tissue dissection technique and confocal calcium imaging. The bladder of a sacrificed adult female NM

the deregulation of stim1 and store operative calcium entry (soce) impaired aortic smooth muscle cells contractility in aortic medial degeneration. 热度: 3D co-culture model to analyze the crosstalk between endothelial and smooth muscle cells.三维培养模型,分析血管内皮和平滑肌细胞之间的串扰 ...
Smooth muscle cells also proliferate and migrate upon the activation of chemical and mechanical factors, which modulates tissue homeostasis and development. Unfortunately, uncontrolled vascular smooth muscle contractility results in the development of hypertension. Aberrant airway smooth muscle reactivity leads ...
Airway smooth musclemay be the only smooth muscle tissue in the body for which the normal physiologic function is unknown. Although a number of hypotheses have been advanced for the function of airway smooth muscle, there is considerable debate as to whether it has any beneficial function at all...
