    Fig. 1. (A) Schematics of the 2D and 3D culture formats used throughout this work. Both formats contained 40,000 T47D cells that were either plated directly in a commercial 96 well plate or suspended in collagen I and seeded into a paper-based scaffold with a 1 × 10−3 cm3 culture zone. Once seeded, the paper-based scaffolds were also placed in a com- mercial 96 well plate. All experiments were in- cubated under normoxic (21% O2) or hypoxic (1% O2) conditions in E2-deprived (Veh) or -supple- mented (E2) medium for 24 h.
