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

Myeloid progenitor cells derived from the bone marrow of mice are stimulated using a cytokine mixture to become myeloid derived suppressor cell (MDSC) like cells. These are co-cultured with activated CD8+ T-cells derived from a mouse spleen. The MDSC like cells will suppress the proliferation of the

This study aimed to create a versatile and reproducible in vitro model of a human motor unit with functional neuromuscular junctions (NMJs). Therefore, human induced pluripotent stem cell (hiPSC)-derived motor neurons and human primary mesoangioblast (MAB)-derived myotubes were co-cultured in

Using the ex vivo culture system, we investigated the impact of an endoscopic helium plasma jet application on mouse ISCs at the morphological, cellular and transcriptomic levels. Moreover, we explored the potential selectivity of CAP application on tumor versus normal organoids originating from the

This method relates to the development of highly reproducible human iPSC-derived neurospheroids equipped with intrinsic bioluminescence for an easy and longitudinal follow-up of the viability and growth of these neurospheroids over time. The luminescent neurospheroids have been applied in ischemic

Cultivated liver cells are fixed with 4% (w/v) paraformaldehyde (PFA) for 10 minutes at room temperature and subsequently incubated for 15 minutes with 100 mM glycin solution, used to saturate reactive groups generated after PFA fixation. These cells are subsequently incubated for 10 minutes with 1%

The goal of chicken embryonic spinal cord electroporation is to increase or to reduce expression levels of genes of interest in the developing spinal cord, and to assess the phenotypic consequences of these alterations on neuronal differentiation or migration. Fertilized eggs stored at 14°C are

For the risk assessment of compounds migrating from food contact materials (FCM), information on the exposure to the migrant as well as its possible hazards is needed. To support the evaluation of both starting products and NIAS from plastic FCM, the VERMEER FCM tool has been developed within the

The in vitro micronucleus test is a genotoxicity test for the detection of micronuclei in the cytoplasm of interphase cells and has been described in detail in OECD TG 487. Micronuclei may originate from acentric chromosome fragments (i.e. lacking a centromere), or whole chromosomes that
