In drug discovery, MSCs play a central role in shaping therapeutic outcomes across indications. Their involvement in fibrosis, tumor microenvironment dynamics, inflammation, and regenerative processes make insights from in vitro MSCs models valuable in the context of drug development for understanding how stromal signalling influences tissue structure and function. Stromal models enable researchers to investigate cell-cell and cell-matrix interactions, modulate immune and epithelial behavior, and drive differentiation into adipogenic, osteogenic, or chondrogenic lineages. These platforms support the assessment of microenvironment-driven drug response, target engagement, disease modeling and context-specific toxicity when implemented as part of new approach methodologies (NAMs).

Stromal models also strengthen translational research by enabling mechanistic studies of fibrosis, oncology, and tissue regeneration. Researchers can quantitatively evaluate differentiation potential, extracellular matrix deposition, and paracrine signaling to support biomarker discovery and functional target validation. By incorporating human stromal systems into development workflows, teams can gain a better understanding of tissue-specific responses and improve prediction of therapeutic efficacy and safety.
