However, the mechanistic bases by which mechanical forces remodel the extracellular milieu—and how such forces can be rationally exploited to reprogram mechanotransductive signaling—remain incompletely resolved. This knowledge gap poses a major barrier to the clinical translation of mechanotherapeutic approaches. In this review, we synthesize current understanding of cutaneous biomechanics and its intimate interplay with wound-healing cascades, and we delineate the principal mechanotransduction pathways that convert physical stimuli into cellular fate decisions.

The framework was evaluated using PEGylated gold nanoparticles (AuNPs) spanning a range of particle sizes and incorporated empirical size-parameter relationships to enable in vitro<em>-</em>in vivo translational analysis. Model simulations suggested that transcytosis-mediated processes account for the majority of tumor AuNP accumulation under the modeled physiological conditions (99.0 %, 95 % CI: 94.7 %–99.8 %), whereas passive diffusion contributed a smaller fraction under most conditions examined. Dose-dependent analysis further indicated a capacity-limited tumor accumulation behavior, with a threshold around 18 mg, beyond which increasing the dose to 100 mg resulted in only a modest (∼15 %) increase in tumor accumulation. Sensitivity analyses indicated that systemic exposure and endothelial intracellular trafficking behavior are key determinants influencing tumor delivery, whereas enhanced intracellular sequestration consistently reduced tumor accumulation across dose levels.
