background: the rh antigens are expressed as parts of a protein complex in the rbc membrane. this complex is a tetramer, consisting of two molecules of rhag and two molecules of rh proteins. to express rhd in rbc membrane, expression of rhag is essential. this co-expression only occurs in the erythroid lineage. k562 cell line has an erythroid lineage. materials and methods: cord blood was used ...

Kidney-derived Madin Darby canine kidney (MDCK) cells form lumina at their apices, and target luminal proteins to an intracellular vacuolar apical compartment (VAC) when prevented from polarizing. Hepatocytes, by contrast, organize their luminal surfaces (the bile canaliculi; BC) between their lateral membranes, and, when nonpolarized, they display an intracellular luminal compartment that is d...

An epithelial cell line (MDCK) was used to prepare monolayers which, in vitro, develop properties of transporting epithelia. Monolayers were formed by plating cells at high densities (10(6) cells/cm2) on collagen-coated nylon cloth disks to saturate the area available for attachment, thus avoiding the need for cell division. An electrical resistance developed within 4-6 h after plating and achi...

BACKGROUND/AIMS It has been shown that MDCK cells, a cell line derived from canine renal tubules, develop cell domes due to fluid pumped under cell monolayer and focal detachment from the adhesion surface. In vitro studies have shown that primary cilia of kidney tubular epithelial cells act as mechanosensors, increasing intracellular calcium within seconds upon changes in fluid shear stress (SS...

introduction: inactivated influenza vaccines are traditionally produced in chicken embryonated eggs but its limitations in producing the required doses in pandemic outbreaks quickly enough has made searching for alternative modes of production necessary. the use of cell culture-based vaccine production is one way of overcoming the limitations of the egg-based method and securing a more rapid re...

We have demonstrated for the first time that a mink lung epithelial cell line (Mv1Lu) supports the replication of influenza A and B viruses, including the recently isolated H5N1 avian and human Hong Kong strains, to titers comparable to those in MDCK cells. These results suggest that Mv1Lu cells might serve as an alternative system for the isolation and cultivation of influenza A and B viruses ...

Adipokine-producing fatty tissues, composed of preadipocytes, adipocytes, and mesenchymal stem cells, surround the kidney. To study the interaction between renal tubular cells and adipose tissue, we cocultured adipose tissue fragments and MDCK cells. MDCK cells in the coculture showed a taller columnar shape with improved organization of their microvilli and basal lamina than that seen in MDCK ...

This paper reports the measurement of refractive index (RI) and thickness of living cells using cell culture chip integrated with micro-indicators via immersion refractometry. In the experiment, the RI and the thickness of the cultured MadinDarby canine kidney (MDCK) cell line are obtained simultaneously. As this method features high accuracy, no damage to a group of the living cells and real t...
