Smooth muscles are made of individual cells that can vary notably in size, from 20μm in length in the walls of the small blood vessels to 200 to 300μm in length in the intestine. The smooth-muscle cell is cha
The scanning electron microscope shows that the end of each muscle fiber in the junction has a jagged dome shape (Fig. E16). This jagged contour increases the surface area of contact between the muscle and tendon, thereby increasing its strength (Fig. E17). Electron micrographs also show that...
Smooth muscle cells (SMCs) are vital in maintaining the structural and functional integrity of hollow organs. When SMCs are injured, rather than regenerating they are partially replaced by fibroblasts and scar tissue [1]. Over time, these injuries can result in compromised function and in a wide...
In 11 days many cells died and detached from substrate, while actin filaments became poor except for the surface membrane in the remained cells. Appearance of calcium response to noradrenalin needed several days after passage as well as a morphological change of the cells for the extended form ...
and facilitates the assessment of cellular morphology (Fig.1g). At 96 h.p.i., CHERRY+cells coexpressing ɑ-actinin lacked myofibrillar structures and had the appearance of immature cardiomyocytes (Extended Data Fig.2f). In contrast, we observed CHERRY+cells coexpressing MHC and ɑ-actinin at...
14.The microscopic appearance of a leiomyoma indicates that the cells do not vary greatly in size and shape and closely resemble normal smooth muscle cells.镜下观,平滑肌瘤细胞大小和形态没有很大变化,和正常平滑肌细胞非常相似。 15.Inhibition of Doxazosin on Proliferation of Rat Vascular Smooth Muscle...
The appearance of the fetus and organs were noted. Representative tissue samples were taken and frozen in liquid nitrogen. The presence of the opposite sex DNA in the fetal tissues was used to verify chimaerism. DNA extraction of 150 mg of tissue was performed39. PCR amplification of ...
Normal, healthy human breast tissue from a variety of volunteer donors has become available for research thanks to the establishment of the Susan G. Komen for the Cure® Tissue Bank at the IU Simon Cancer Center (KTB). Multiple epithelial (K-HME) and stromal cells (K-HMS) were established...
Currently, dressings are the most common form of cell-based products used in burn therapy [41]. Their shape, however, does not provide a possibility to treat large and complex wounds with a heterogeneous surface profile. Therefore, such technologies as cell spraying and three-dimensional (3D) ...
Muscle fibers or cells generally extend from tendon to tendon in a muscle and do not branch or form syncytia. In cross sections, fibers have a polygonal or multifaceted shape in muscle of adults. Many factors, such as species, breed, age, weight, sex, plane of nutrition, position and func...
