Abstract

The present invention relates to isolated nucleic acid molecules, comprising a functional mammalian EGR-1 (early growth response protein 1) promoter region that is operatively linked to a gene encoding either a fluorescent protein or a gene encoding an siRNA directed against a constitutively expressed fluorescent protein and controls expression of said gene. The present invention further relates to nucleic acid vectors, comprising said nucleic, cells comprising said nucleic acids or vectors, being capable of sensing and indicating fluid shear stress acting on themselves, and methods of generating the same. Furthermore, the present invention relates to methods of evaluating fluid shear stress acting on cells in real-time during the operation of a biotechnological device or system, methods of evaluating a biotechnological device or system with respect to fluid shear stress acting on cells caused by operation of said device or system, and methods of designing a biotechnological device or system, said methods using said cells.
