To facilitate the search for contacts for in vitro methods at the TiHo, working groups that have established the listed methods in their laboratories are listed here.
Institute for Food Quality and Food Safety, Research Group Seeger
- Differentiation of human induced pluripotent stem cells (hiPSCs) into different neuronal target cells (e.g. motor neurons, sensory neurons, brain spheres)
- Generation of intestinal organoids from hiPSCs or intestinal stem cells isolated from the intestine of different species
- Cell culture of cell lines from different species
Performance of various tests in cell culture
- activity assay of botulinum toxins in motor neurons differentiated from human induced pluripotent stem cells (hiPSCs) (Western blot, luminescence assay)
- cytotoxicity assays and cell proliferation assays (MTT, WST, LDH, ...)
- assays for the detection of enzyme activities (CYP1A1, CYP2B1, ...)
- characterization of barrier properties in intestinal epithelial cells via measurement of transepithelial resistance (TEER) and via fluorescence markers (Lucifer-Yellow) in transwell inserts
- Western blot (cleavage of SNARE proteins, HIF1-alpha expression,...)
- Immunofluorescence staining (neuron-specific markers, markers for specific cells of the intestinal epithelium)
- RT-qPCR (expression of differentiation markers, inflammatory markers,...)
- Flow cytometry (stem cell markers, differentiation markers,...)
- ELISA (cytokine release,...)
