This study reveals that multicellular aggregation induces metabolic reprogramming via mechanical compaction in lieu of formation of a hypoxic core. Utilizing biomechanical knowledge gained from planar culture, we set forth a novel three-dimensional (3D) model of size-dependent cortical compaction and demonstrated its role in metabolic reconfiguration. Ultimately, this study establishes mechanical compaction and its spatial gradients as key regulatory factors and design parameters in the development of 3D human adipose-derived mesenchymal stem cell aggregates.
