The chambers used for 3D TE have three main corresponding features. (1) They are anchored by fixed point(s). (2) They have a geometric configuration that is rectangular. (3) The chambers are used with a natural (compliant) matrix. The hydrogel matrix/scaffold used for supporting cells varies between the models, as does construct volume, cell type, and seeding density per milliliter (latter not displayed).
