Much of the work on the metabolic support of transport in the kidney has utilized renal homogenates, renal slices and isolated renal tubules. However, these are not ideal systems because of their limited luminal access for transport and/or their anaerobic nature. Isolated perfused kidney and microperfused tubular segments have also been used for this purpose and do not have the above disadvantages. A useful additional tool is the use of isolated renal cells in suspension, in which access to luminal transporters and diffusion of oxygen would not be limiting.KeywordsCortical TubuleCytosolic RedoxRenal HomogenateRenal GluconeogenesisZealand White Male RabbitThese keywords were added by machine and not by the authors.
