Background: Staphylococci are recognized worldwide as one of the most important etiological agents of bovine mastitis due to their virulence factors such as their ability to penetrate inside mammary epithelial cells and their ability to form biofilm. Aims: The objectives of this study were to establish a model of primary mammary epithelial cells origin...

BACKGROUND In recent years, liver transplantation in patients with hepatocellular cancers and cirrhosis has been restricted to those with small cancers (<5 cm for solitary and <3 cm for multifocal HCC with <3 nodules). The selection of patients for liver transplantation is based on pre-operative imaging. The accuracy of imaging correlated with explant histology and the effect of tumour stage ha...

To optimize conditions for micropropagating Galanthus transcaucasicus Fomin, the effect of explant type, different concentrations of sucrose, type and different concentrations of auxin were examined on bulblet production. For the induction of bulblets, three types of bulb scales were usesd as explants. A two-step sterilization procedure was applied. Assessments were made after incubation for 20...

to produce embryogenic callus and somatic embryos, tendril explants were collected and cultured in ms medium supplemented with various concentrations of hormones. after one month most of explants produced callus. the highest percent of embryogenic callus obtained in ms medium supplemented with 4.5 µm bap and 1µm 2,4-d. production of somatic embryos was depended on genotype and medium. yaghouti ...

Automation of cell culture would facilitate stable cell expansion with consistent quality. In the present study, feasibility of an automated closed-cell culture system "P 4C S" for an embryoid body- (EB-) explant outgrowth culture was investigated as a model case for explant culture. After placing the induced pluripotent stem cell- (iPSC-) derived EBs into the system, the EBs successfully adher...

Explant of trigeminal ganglia neurons in adult rats induces perineuronal glial proliferation of primarily satellite cells as opposed to Schwann cells. This proliferation begins at 15 h after explant culture and by 27 h there is a significant increase in glial proliferation as measured by scintillation counts of [3H]thymidine. Blocking protein synthesis between 0 and 3.5 h after explant culture ...

Several studies have shown that decidual tissue produces soluble factors which can mediate a variety of immunosuppressive activities. In order to assess whether prostaglandin E2 (PGE2) was present in supernatants produced by explant culture of 10 human specimens of first trimester decidua. The effect of the supernatants from the two different series (with and without indomethacin treatment) of ...

Ex vivo explant culture models are powerful tools in bone research. They allow investigation of bone and cartilage responses to specific stimuli in a controlled manner that closely mimics the in vivo processes. Because of limitations in obtaining healthy human bone samples the explant growth of animal tissue serves as a platform to study the complex physico-chemical properties of the bone. More...

Growth plate cartilage regulates the rate of growth and ultimate length of several bones in the skeleton. Chondrocytes within the growth plate proliferate, differentiate, enlarge, and die. The extracellular matrix undergoes synthesis, reorganization, and eventually degradation. The majority of research in growth plate physiology has focused on the proliferation and differentiation of chondrocyt...
