1. A bioartificial kidney comprising:
- a microfluidic flow channel comprising at least one topographical surface;
an inlet in fluid connection with the flow channel for allowing fluid to flow into the flow channel; and
renal cells seeded on the topographical surface as a confluent monolayer;
whereinthe topography of the surface of the flow channel comprises ridges parallel to a length of the microfluidic flow channel and having a width less than 5 μ
m and wherein the confluent monolayer of renal cells forms a substantially fluid-impermeable barrier.

33. A bioartificial kidney comprising:
-
a microfluidic flow channel comprising at least one topographical surface; an inlet in fluid connection with the flow channel for allowing fluid to flow into the flow channel; and renal cells seeded on the topographical surface; wherein the topography of the surface of the flow channel comprises ridges parallel to a length of the microfluidic flow channel and having a width of about 1 μ
m or about 3 μ
m and is selected to cause the renal cells to form a cell layer disposed on the surface to achieve an arrangement, behavior, or morphology determined at least in part by the topography of the at least one surface.
