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.

A hydrodynamic mechanosensory hypothesis for brush border microvilli
American Journal of Physiology-Renal Physiology, 2000In the proximal tubule of the kidney, Na+ and HCO3 − reabsorption vary proportionally with changes in axial flow rate. This feature is a critical component of glomerulotubular balance, but the basic mechanism by which the tubule epithelial cells sense axial flow remains unexplained.

Double membrane-bounded intestinal microvilli in Oncopeltus fasciatus
Cell and Tissue Research, 1983A double plasma membrane (DPM) surrounding intestinal microvilli of the migratory milkweed bug, Oncopeltus fasciatus, is described. Mutant and wild types of the phytophagous insect have been studied by conventional SEM and TEM procedures with the use of membrane-enhancing staining methods. Longitudinal and transverse sections revealed a DPM surrounding

Renal ischemia induces tropomyosin dissociation-destabilizing microvilli microfilaments
American Journal of Physiology-Renal Physiology, 2004Ischemic-induced cell injury results in rapid duration-dependent actin-depolymerizing factor (ADF)/cofilin-mediated disruption of the apical microvilli microfilament cores. Because intestinal microvillar microfilaments are bound and stabilized in the terminal web by the actin-binding protein tropomyosin, we questioned whether a protective effect of ...

Metastatic Spindle Cell Malignant Melanoma with Prominent Microvilli
Ultrastructural Pathology, 1992A metastatic spindle cell malignant melanoma with positive immunoreactivity for S-100 protein and HMB-45 antigen and the presence of premelanosomes is described in a lymph node of the neck 11 years after removal of a superficial spreading malignant melanoma from the arm.

Involvement of Gicerin in the Extension of Microvilli
Experimental Cell Research, 2001Gicerin is a cell adhesion molecule belonging to the immunoglobulin superfamily. To study the functional differences between l- and s-gicerin, we first examined the distribution of endogenous gicerin in B16 cells and found that l-gicerin was densely localized in microvilli.

Preferential distribution of surface immunoglobulins on microvilli
Nature, 1978MOST lymphocyte surface molecules including surface immunoglobulin (s-Ig) are mobile and essentially randomly dispersed in the plane of the membrane (reviewed in ref. 1). It has been recently shown, however, that a spontaneous non-uniform redistribution of surface molecules such as s-Ig (ref.

CHOLESTASIS: PUMP FAILURE, MICROVILLI DEFECT, OR BOTH?
The Lancet, 1978Cholestasis may result either from a disturbance of the systems responsible for solute transport into the bile canaliculi (for example, the Na+ and K+-ATP-ase system) or from an alteration of canalicular microvilli (for example, that resulting from microfilament dysfunction).

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+.
