The cross talk between immune cells and tissue cells controls inflammation and is mediated by mediators such as chemokines, cytokines and others. This network of signals can be modulated therapeutically by drugs.
The effect of drugs on such omplex regulation can be analysed reliably only in an environment that represents the complexity of such feedback systems. HOT Screen GmbH developed a series of proprietary human organotypic co-culture test systems combining whole-blood cultures with cultures of differentiated intestinal epithelia, 3D epidermis, bronchial epithelia, etc. These allow to study drug effects on immunoregulation even in in-vivo-like human inflamed tissue environments.
Multiplexed Luminex® assays (MAP tests, MyriadRBM) were used as complex readouts when testing drug effects on cell activation.
Basic fibroblast growth factor (bFGF) is widely used in vitro for the maintenance and stimulation of a variety of cells. However, use of native bFGF in cell biology is limited by the fact that bFGF rapidly degrades at physiological temperatures. We have addressed this problem with an engineered form of bFGF, named Heat Stable bFGF (HS bFGF), which is stable at 37 degrees Celsius.READ MORE
