WebApr 15, 2024 · Here we introduce an instrument that measures transepithelial electrical resistance (TEER) of perfused epithelial tubes in the microfluidic OrganoPlate platform. The tubules are grown in microfluidic channels directly against an extracellular matrix, obviating the need for artificial filter membranes. WebOct 6, 2016 · The total CFTR Cl−conductance of the apical membrane is dependent on three parameters: the activity, or open state probability (Po) of CFTR, which is controlled predominantly via cAMP/PKA phosphorylation as described in chapter “Biochemistry and physiology of CFTR”; the number or density of CFTR channels (N), and finally the single …

WebJun 27, 2005 · Main Results: Primary cultures of ΔF508 CF bronchiolar epithelial cells displayed higher transepithelial resistance than non-CF cultures, whereas baseline short circuit current and amiloride-inhibitable short circuit current were similar in both preparations. The ASL height was significantly smaller in CF compared with non-CF preparations. WebFor measurements of transepithelial resistance (Rte ), current must be injected across the epithelium to perturb Vte. This is most easily accomplished when the epithelium can be … is service taxable in indiana
