1. A method of determining toxicity of a test agent in a tissue comprising:
- A) incubating a test agent within a three-dimensional structure comprising a first mold or polymer scaffold, a semi-permeable membrane, and a second mold or polymer scaffold, wherein the semi-permeable membrane is disposed between the first and second molds or polymer scaffolds, and wherein the first mold or polymer scaffold has microchannels that form a fluidic branching network that mimics the forces and transport of natural vasculatures and wherein the second mold or polymer scaffold comprises cells;
B) examining a change in the cells; and
C) correlating the change in the cells of step B) with toxicity of the test agent in said cells.

Abstract
A method of determining toxicity of a test agent in a tissue including A) incubating a test agent within a three-dimensional tissue engineered structure comprising a first mold or polymer scaffold, a semi-permeable membrane, and a second mold or polymer scaffold, wherein the semi-permeable membrane is disposed between the first and second molds or polymer scaffolds, and wherein the first mold or polymer scaffold has microchannels comprising vessels that bifurcate, and B) obtaining information from step A) to assess toxicity.
