Cluster microvilli in coronary endothelium
Cell and Tissue Research, 1984Examination of cardiac vascular endothelium with scanning electron microscopy, and transmission electron microscopy of previously scanned tissue, revealed several regions of the coronary venous system that contained 'cluster' microvilli. These consisted of 2-15 microvillous projections that emanated radially from a common base or were grouped into a ...

Absorption characteristics of oriented photopigments in microvilli
Biological Cybernetics, 1976We have analysed the effects of photopigment orientation in microvilli membranes on the absorption properties of rhabdomeres.

Microvilli on the Outside of a Nematode
Nature, 1970THE females of insect parasitic nematodes of the order Tylenchida are bizarre in form and live in the haemocoels of their hosts1–3. After the infective larva enters the haemocoel it usually moults, grows rapidly and becomes sexually mature. Its feeding apparatus quickly degenerates, the mouth and anus often disappear and if the intestine persists it ...

Microvilli of endometrial epithelium in relation to ovoimplantation
American Journal of Obstetrics and Gynecology, 1965Abstract Microvilli, on the free border of endometrial cells lining the uterine cavity in the rat, vary in size and configuration as a result of different hormonal environments. Microvilli are a means by which the free surface area of the epithelial cell is increased.

The morphological and functional diversity of apical microvilli
Journal of Anatomy, 2022AbstractSensory neurons use specialized apical processes to perceive external stimuli and monitor internal body conditions. The apical apparatus can include cilia, microvilli, or both, and is adapted for the functions of the particular cell type. Photoreceptors detect light through a large, modified cilium (outer segment), that is supported by a ...

Branching Microvilli in the Nasal Respiratory Epithelium
Archives of Otolaryngology - Head and Neck Surgery, 1978In an ultrastructural study of the respiratory epithelial covering of 14 human nasal mucous polyps, some of the microvilli overlying the ciliated cells were shown to exhibit a complex form of branching with a resultant increase in surface area. This apparently original observation is of uncertain significance but is not of definite pathological ...

Dynamics of Immune Cell Microvilli
2023Microvilli are actin-based microscopic membrane protrusions that are present in a wide variety of immune cells. Scanning electron microscopy (SEM) revealed that the T cell surface is covered by microvilli. Growing evidence shows that microvilli play important roles in T cell antigen detection and signal transduction.

Scanning electron microscopy of intestinal microvilli
Journal of Microscopy, 1969SUMMARYThe usual simple methods for the preparation of soft tissues for scanning electron microscopy failed to demonstrate the presence of microvilli on intestinal epithelial cells from rats. Treatment with a mucolytic agent or surface‐section methods also failed.

Structure of human placental microvilli.
Ciba Foundation symposium, 1983Cytoskeletons have been prepared from microvilli isolated from the human placental syncytiotrophoblast. They contain actin and a protein similar to fimbrin. In addition, they contain calmodulin and a protein of relative molecular mass (Mr) 105 000, both of which can be released from the cytoskeletons by treatment with Ca2+.

Myosin VIIa as a common component of cilia and microvilli
Cell Motility and the Cytoskeleton, 1998The distribution of myosin VIIa, which is defective or absent in Usher syndrome 1B, was studied in a variety of tissues by immunomicroscopy. The primary aim was to determine whether this putative actin-based mechanoenzyme is a common component of cilia. Previously, it has been proposed that defective ciliary function might be the basis of some forms of
