A novel full-scale computational model of the rat kidney vascular network demonstrates the feasibility of comprehensive modeling of renal hemodynamics and autoregulation.
Enables detailed renal autoregulation simulation; leaves open human translation and clinical relevance.
We have developed the first full-scale steady-state model integrating a realistic vascular network topology of the kidney and its hemodynamic regulatory mechanisms. The vascular network is combined with approximately 30,000 nephron models that include glomerular filtration, tubular reabsorption, and autoregulation of the afferent arteriolar resistances. By simulating the adaptive properties of the renal microcirculation at steady state, our approach demonstrates the feasibility of utilizing a reconstructed vascular network for comprehensive modeling of renal function.
