Figure 1. Hydraulic conductivity, Lp, was measured based on the modified Landis technique in individually perfused microvessels.

Jv is the initial water flow per unit area of microvessel wall (S), which was calculated from the velocity of the marker cell (Vcell) after the vessel was occluded, the vessel radius (r), and the length between the marker cell position and the occlusion site (L).
