1. A method of detecting the response of a tissue to an agent comprising:
- (a) contacting a three-dimensional bio-artificial tissue with an agent, the bio-artificial tissue comprising cells and having an extracellular matrix polymerized therearound, the bio-artificial tissue formed, and suspended on a scaffold support, and overlaying the support without a fastener to facilitate tissue adhesion, the scaffold support being positioned above the bottom of a well with a space between the bio-artificial tissue and the bottom of the well,(b) without removing the bio-artificial tissue from the well, performing a cell-based assay on the bio-artificial tissue in the well, wherein the assay produces an indicator of a physiologic response of the tissue to the agent, and the indicator is suitable for optical detection, and(c) optically detecting a level of the indicator in the well, wherein the level of the indicator is indicative of the response of the bio-artificial tissue to the agent.

23. A method for screening the effects of a pharmaceutical agent on a tissue, comprising:
- a) contacting an agent with a plurality of three-dimensional bio-artificial tissues suspended from and overlaying a plurality of scaffolds without a fastener to facilitate tissue adhesion to the scaffold;
each of the plurality of scaffolds positioned within a well of a multi-well plate without any mesh covering the bottom of the well to provide an array of locations, wherein the agent contacting each bio-artificial tissue is the same or different;
b) without removing the bio-artificial tissues from the wells, performing a cell-based assay on each bio-artificial tissue in the well, wherein the assay produces an indicator of a physiologic response of the tissue to the agent, and the indicator is suitable for optical detection, and c) optically detecting a level of the indicator in each well, wherein the level of the indicator is indicative of the response of the bio-artificial tissue to the agent in each well.
- a) contacting an agent with a plurality of three-dimensional bio-artificial tissues suspended from and overlaying a plurality of scaffolds without a fastener to facilitate tissue adhesion to the scaffold;
