Mechanical forces alter extracellular protein conformation, particularly mechanosensitive ion channels, leading to Ca<sup>2+</sup> influx and subsequent cascades of events that modulate cellular function and behavior. Recent discoveries indicate the potential of mechanotransduction as a novel approach for enhancing immune cell activation in cancer treatment modalities. Antigen-presenting cells (APCs) and T cells have become the focus of novel approaches to combat cancer. While current clinical <em>ex vivo</em> methods for APC activation often demonstrate limited efficiency, mechanotransduction techniques demonstrate remarkable potential for dramatically enhancing APC activation, potentially leading to improved therapeutic outcomes. Researchers have explored the mechanosensitivity of T cells to enhance CAR T therapy's specificity and controllability. Additionally, scientists have mechanically activated cancer cells engineered to express priming antigens, which are critical for synthetic Notch (SynNotch) CAR T cell therapy. Among the various mechanotransduction stimuli, fluid shear stress (FSS) and ultrasound have emerged as new and effective approaches for immune cell activation.

Here we review this emerging research area, where age-related ECM alterations, such as age-induced increases in matrix stiffness, biochemical changes, and resultant dysregulated mechanosensitive pathways, are explored for their influence in cancer initiation and progression. Additionally, recent studies have showed how aged cells contribute to ECM alterations, further reinforcing tumor-permissive changes. This review examines both aspects of ECM aging, i.e. material-driven and cell-driven, and highlights current understandings of how ECM aging influences interactions within the tumor microenvironment in multiple cancer types, with a focus on biomechanical aspects. We also discuss emerging age-mimetic in vitro models facilitating studies of age-dependent cancer progression and therapeutic responses.
