We developed an innovative model to study the effect of the supernumerary X chromosome on KS features. The model was generated using induced pluripotent stem cells (iPSCs) from patients with Klinefelter syndrome (KS) i.e. with a 47, XXY karyotype. In order to compare the potentials of both 47XXY

We tissue-engineer in vitro, skeletal muscle consisting of aligned myofibers. To create the so-called bio-artificial muscle (BAM), human muscle progenitor cells are expanded, and a 3D construct is created by mixing the cells with a hydrogel. The cell-gel mix is cast into custom-made silicone molds

This model is a 3D human co-culture model where both hepatocyte functionality and HSC quiescence can be maintained for at least 21 days. This novel system allows hepatotoxicity testing and can detect drug-induced as well as hepatocyte-dependent HSC activation, thereby representing an important step

Generation of Hepatic Stellate Cells from Human Pluripotent Stem for in vitro liver fibrosis studies
We established a protocol to efficiently generate hepatic stellate cells (HSCs) from human pluripotent stem cells (PSCs). Our procedure generated complex in vitro spheroid cultures that better mimic the complexity of the liver as well as liver function. In co-culture, iPSC-HSCs promote maintenance

In this method, we use rabbit monoclonal antibodies that are produced in vitro to identify xenografted human stem cell-derived hepatocytes in frozen murine liver slices. These recombinant antibodies were produced in vitro by cloning antibody genes for immune-specific heavy and light antibody chains

Intestinal organoids are cultured from intestinal biopsies obtained during routine endoscopy. The stem cell containing crypts are isolated and cultured in a 3D ECM (Matrigel) in the presence of the desired growth factors. The present stem cells will expand and give rise to all epithelial cells of

Alkaline comet assay (COM) and Micronucleus test (MN) are well-established cytogenetic tests that are used to detect both immediate damages i.e. DNA fragmentation, and permanent damage which results in micronuclei formation. These techniques are often applied separately or, sometimes, in combination

The CALUX method is an in vitro bioassay that uses reporter gene cell lines that have been stably transfected with a luciferase reporter gene under the control of relevant receptor specific DNA response element. This enables the screening for chemicals that can bind to specific receptors and

Metabolomics and 13C tracer analysis are state-of-the-art techniques that allow determining the concentration of metabolites and the activity of metabolic pathways, respectively. Three dimensional (3D) cultures of cancer cells constitute an enriched in vitro environment that can be used to assay

Isolation Femoral and tibial bones are isolated from 10-12 weeks old C57BL/6J mice. After cutting the bone's ends, the bone marrow is flushed out using a 23G syringe with PBS into a 50ml falcon tube. After centrifugation cells are re-suspended in FCS (0.5ml/mouse leg). Differentiation 0.5ml of the
