Adult skeletal muscle regeneration is orchestrated by a specialized population of adult stem cells called satellite cells, which are localized between the basal lamina and the plasma membrane of myofibers. The process of satellite cell-activation, proliferation, and subsequent differentiation that occurs during muscle regeneration can be recapitulated ex vivo by isolation of single myofibers fr...

A rapid culture test has been developed and evaluated for the detection of adenovirus in ocular infections. The test requires only two days' incubation of the inoculated cell monolayers on coverslips in flat bottomed tubes followed by detection of adenovirus inclusions using immunofluorescence staining method. The sensitivity of the rapid test is found to be comparable with that of the conventi...

At one time it was thought that biliary epithelial cells simply formed the lining to the tubular conduits which constitute the biliary tract. Development of in vitro systems for culturing biliary epithelial cells has enabled functional studies which increasingly show that this is far from true, and that biliary epithelial cells do have important functional roles. Disruption of these functions m...

Permeation of a drug through the cornea may be studied in vitro by using either the excised cornea of slaughtered animals or an organotypic cornea construct [1]. To compare drug permeability data reported in the literature for excised porcine cornea [2] with those from cornea constructs, the cultivation of an organotypic porcine cornea is required. The porcine cornea consists of three major cel...

mycoplasma synoviae (m. synoviae) is a major worldwide poultry pathogen that causes serious economic losses in the poultry industry. this study was designed to detect m. synoviae through culture isolation and polymerase chain reaction (pcr) assay to demonstrated the involvement of m. synoviae infection in trachea and the lung/air sac samples taken from commercial broiler chicken farms in 3 m...

The quality of the hepatocytes used for clinical cell transplantation is very important, and depends to a large extent on the nature of the tissue used for isolation. The collagenase perfusion technique to isolate hepatocytes from animal livers has been further developed for isolation of human hepatocytes. As the donor organ pool is a scarce resource, marginal livers unsuitable for transplantat...

A method for isolation of mouse liver cells by a two-step perfusion with calcium and magnesium-free Hanks' salt solution followed by a medium containing collagenase is described. Several variations of the commonly used procedure for rat liver cell isolation were quantitatively compared with respect to cell yield and viability. The optimal isolation technique involved perfusion through the hepat...

Although it has been 68 years since Winogradsky (1890) accomplished the first isolation of nitrifying bacteria, the methods employed have not been improved significantly, and pure cultures remain incredibly difficult to obtain. The literature records numerous attempts to secure Nitrosomonas in pure culture. Nevertheless, the organism has seldom been isolated by dilution techniques. In the relat...

The number of mitochondria per cell varies substantially from cell line to cell line. For example, human HeLa cells contain at least twice as many mitochondria as smaller mouse L cells. This protocol starts with a washed cell pellet of 1-2 mL derived from ∼10⁹ cells grown in culture. The cells are swollen in a hypotonic buffer and ruptured with a Dounce or Potter-Elvehjem homogenizer using a ti...

Herein, we presented the first report on bluetongue (BT) disease in 10 pregnant camels in a herd fromKerman province, Iran. All sera samples were tested serologically (AGID, C-ELISA). We also used the Razi-BK cell line, performed primary culture of ovine kidney and inoculated intravenously the embryonatedchicken eggs (ECE) to culture and isolate the BT virus. Efforts to culture and isolation of...
