[Theodor Huzella and the initiation of research on the interactions between cells and the extracellular matrix].

Interactions between cells and the surrounding "biomatrix", mediated by receptors as integrins or the elastin receptor is the most important topic in up to date research on connective tissues. Looking for the origin of this concept, one finds the pioneering work of Theodor Huzella, professor of histology-embryology at the Medical University of Budapest during pre-world war II decades. Using time-laps micro-cinematography in reflected light, he visualized the important role of connective tissue fibers, prepared in his laboratory, for the oriented migration of normal and malignant cells. His theoretical explanations, attributing an "active" role to the elasticity of the argyrophilic fibrous network in the coordination of cell societies, can now be reinterpreted in the light of recent work on the mechanotransduction of "messages" from the extracellular matrix to the cell inside. We propose a succinct review of Huzella's work and theories reinterpreted in the light of up-to-date knowledge on cell-matrix interactions.
