12. Getting Started Introduction Fluid induced shear stress occurs in every tissue in the body as a result of interstitial fluid movement Tissue deformation by compression tension shear forces results in the movement of interstitial fluid around cells Fluid movement acts as transport vehicle for ions proteins carbohydrates and other molecules capable of movement within the matrix As the fluid moves past cell membranes a shear stress is generated If one assumes that laminar flow occurs through a parallel plate flow chamber fluid induced shear stress values can be determined with the following formula 6uQ bh where is the shear stress dyne cm u is the viscosity of the fluid in dyne s em Q is the flow rate in ml s b is the width of the flow channel in cm and is the height of the flow channel in cm Shear stress in the vascular system may vary from less than 1 to more than 35 dyne cm Fluid shear stress in canaliculi of bone may vary from 1 to 20 dyne cm while in cartilage it may be in the range of 1 to 5 dyne cm The Streamer is a parallel plate flow system that is used to apply fluid induced shear stress to cells grown in a monolayer The system includes a six chamber laminar flow device designed to hold 75 x 25 x 1 mm Culture Slips Cells are cultured on these matrix coated glass slides StreamSoft software controls a peristaltic pump thereby regulating the flow rate into the chamber and t
