Controlling Signals, Signal Propagation and Signal Transduction

Abstract

When thousands and billions of cells have to fulfil the task to collectively construct an organism with its complex tissues and organs a manifold of mutual agreements are necessary. Controlling cells, for example organizing centres in early embryos, must emit coordinating signals. In order to respond to the signals cells must have the correct equipment including receptors and downstream intracellular signalling systems, which are cell-type specific.
