Title of Course: 
Molecular basics of growth factor signalling and cell-mechanics in regeneration and repair
booked/available seats:

Description: 

Goal of this 3 day workshop is to give an introduction into the crossroads of growth factor signalling and mechanobiology in physiology, pathology and regeneration. Theoretical aspects of the workshop will cover basic concepts in cell-sensation of mechanical cues, integration of extracellular matrix biology and external mechanical cues into intracellular signalling (Prof. Dr. P.Knaus, C.Hiepen, M. Reichenbach) and coupling of mechanobiology with chromatin and gene transcription (Prof. Dr. Sigmar Stricker and Prof. Dr. Petra Knaus). Practical aspects will highlight technologies to apply and measure cellular forces, to investigate on the cells force sensing machinery, it’s subcellular localization(Dr. C. Hiepen, Dr. M. Reichenbach) and in-silico prediction of genes that underly mechano-dependent regulation (Jerome Jatzlau). The students will review and present primary research articles and review that provide state of art data and concepts in mechanobiology and signal transduction. This workshop is particularly suited for students who want to work at the translational interface of physics, bioinformatics and cell biology.
