Techniques to provide in vitro tissue culture have undergone significant changes during the last decades, and current applications involve interactions of cells organoids, three-dimensional cell co-cultures, organ/body-on-chip tools. Efficient computer-aided mathematical model-based methods are required for efficient knowledge-driven characterization, optimization, routine manufacturing systems...

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...

background: linoleic acid (la) is a polyunsaturated fatty acid present in high concentrations in follicular fluid, when added to maturation culture media, it affects oocyte competence.objective: in the present study, we investigated effect of linoleic acid supplementation on in vitro maturation, embryo development and apoptotic related gene expression in ovinematerials and methods: the experime...

Our aim was to determine if the detection rate of infection of total hip replacements could be improved by examining the removed prostheses. Immediate transfer of prostheses to an anaerobic atmosphere, followed by mild ultrasonication to dislodge adherent bacteria, resulted in the culture of quantifiable numbers of bacteria, from 26 of the 120 implants examined. The same bacterial species were ...

conclusions our underlying hypothesis is that recapitulating the three-dimensional early embryonic structure, in order to reproduce better in vitro the three-dimensional morphogenetic-like re-arrangements, would improve cells differentiation, when in vivo transplanted; moreover, it could be used as a simplified cancer disease model and reliable drug evaluation method as well. results the proces...

introduction: antibiotic supplements are regularly used in neuronal culture media to control contamination however, they can interfere with the neuronal excitability and affect electrophysiological properties. therefore, in this study, the effect of penicillin/streptomycin supplements on the spontaneous electrophysiological activity of hippocampal pyramidal neurons was examined. methods: electr...

The repair or replacement of damaged tissues using in vitro strategies has focused on manipulation of the cell environment by modulation of cell-extracellular matrix interactions, cell-cell interactions, or soluble stimuli. Many of these environmental influences are easily controlled using macroscopic techniques; however, in co-culture systems with two or more cell types, cell-cell interactions...

Plant tissue culture techniques were used to study the effect of NaCl on tropane alkaloids accumulation and proline content of both Datura metel and Datura stramonium. Callus cultures were established for both Datura species. However, MS medium supplemented with 1mg/l of both BA and NAA was the best for callus production in D. metel, while MS supplemented wit...
