The experiment was conducted to establish an efficient and reproducible protocol for the plant regeneration and genetic transformation in white Jute (Corchorus capsularis L.). The regeneration and transformation processes depend on optimum growth conditions, suitable explants and varieties. An attempt was made for Agrobacterium mediated genetic transformation in white jute varieties using gene ...

BACKGROUND Bone graft studies lack standardized controls. We aim to present a quick and reliable method for the intra-operative generation of acellular bone explants. METHODS Therefore, ovine cancellous bone explants from the iliac crest were prepared and used to test several methods for the induction of cell death. Over night heat inactivation was used as positive treatment control, methods ...

We evaluated whether physiological and pre-eclamptic (PE) placentae, characterized by exacerbated inflammation, presented alterations in pro-inflammatory High Mobility Group Box 1 (HMGB1) and its Receptor of Advanced Glycation End products (RAGE) expression. Moreover, we investigated, in physiological placental tissue, the ability of Low Molecular Weight Heparin (LMWH) to modify HMGB1 structura...

Background: Most interactions between pathogenic microorganisms and their target host occur on mucosal surfaces of internal organs such as the intestine. In vitro organ culture (IVOC) provides an unique tool for studying host-pathogen interactions in a controlled environment. However, this technique requires a complex laboratory setup and specialized apparatus. In addition, issues arise when an...

As a prerequisite for exploring the mechanisms which lead to the formation and maintenance of the precise wiring patterns in the olfactory system, organotypic cultures of olfactory tissue from transgenic mice expressing green fluorescent protein (GFP) under control of the olfactory marker protein promotor have been established. Tissue specimen from embryonic stage 14 were explanted and kept in ...

Due to their unique motile properties, fish keratocytes dissociated from explant cultures have long been used to study the mechanisms of single cell migration. However, when explants are established, these cells also move collectively, maintaining many of the features which make individual keratocytes an attractive model to study migration: rapid rates of motility, extensive actin-rich lamellae...

In vivo induced endothelial injury results in an intimal thickening, mainly caused by stimulation of smooth muscle cells (SMC), which migrate into, and proliferate in, the denuded intima. We evaluated the manifestation and persistence of this stimulus in several in vitro explant and growth assays using aortic explants from either balloon catheter-injured rats or from sham-operated controls. SMC...

The upper respiratory tract mucosa represents the first line of defense, which has to be overcome by pathogens before invading the host. Considering the economic and ethical aspects involved in using experimental animals for pathogenesis studies, respiratory mucosal explants, in which the tissue's three-dimensional architecture is preserved, may be ideal alternatives. Different respiratory muco...

lemon balm (melissa officinalis l.) is an herbaceous perennial plant of the lamiaceae family that has a wide edible and medicinal uses. in this research the potential of five different explants (nodal segments, shoot tip, cotyledon, hypocotyl and leaf segments) on ms mediums supplemented with different concentrations of 6-benzylaminopurine (bap) (2.2, 4.4 and 8.8 µm) alone or in combination wit...
