Abstract

Mechanical signals from the extracellular matrix are crucial in guiding cellular behavior. Two-dimensional hydrogel substrates for cell cultures serve as exceptional tools for mechanobiology studies because they mimic the biomechanical and adhesive characteristics of natural environments. However, the interdisciplinary knowledge required to synthetize and manipulate these biomaterials typically restricts their widespread use in biological laboratories, which may not have the material science expertise or specialized instrumentation. To address this, we propose a scalable method that requires minimal setup to produce 2D hydrogel substrates with independent modulation of the rigidity and adhesiveness within the range typical of natural tissues. In this method, norbornene-terminated 8-arm polyethylene glycol is stoichiometrically functionalized with RGD peptides and crosslinked with a di-cysteine terminated peptide via a thiol–ene click reaction. Since the synthesis process significantly influences the final properties of the hydrogels, we provide a detailed description of the chemical procedure to ensure reproducibility and high throughput results. We demonstrate examples of cell mechanosignaling by monitoring the activation state of the mechanoeffector proteins YAP/TAZ. This method effectively dissects the influence of biophysical and adhesive cues on cell behavior. We believe that our procedure will be easily adopted by other cell biology laboratories, improving its accessibility and practical application. [ABSTRACT FROM AUTHOR]

Abstract

The co-transcription factors YAP/TAZ are potent inducers of tissue and organ growth during development and tissue regeneration after damage. In this work we have expanded on the repertoire of YAP/TAZ regulations and on their biological properties. We found that these are regulated by the mechanical properties of the microenvironement and by the Wnt signaling cascade. The latter is induced by mutations in the tumor suppressor APC, a hallmark of intestinal cancer, and here we show that this is accompanied by YAP/TAZ stabilization and is functional for transformation of intestinal cells. Both the mechanical and Wnt regulations have been published (Azzolin et al., 2014; Aragona et al., 2013). Aberrant YAP/TAZ activation is known to be associated to tissue overgrowth, tumorigenesis and acquisition of cancer stem cell traits. Here we explore the role of YAP/TAZ as key factors in somatic stem cell self-renewal and somatic cell plasticity (unpublished).

Abstract

The article presents study on YAP/TAZ activity which prevents tissue senescence and aging by controlling cGAS/STING in stromal cells. Topics include information on induction of cell senescence; key challenge is the identification of pathways normally suppressing senescence; and structural and functional decline of ageing tissues to attenuated function of YAP/TAZ.

Abstract

In spite of tremendous advances made in the comprehension of mechanotransduction, implementation of mechanobiology assays remains challenging for the broad community of cell biologists. Hydrogel substrates with tunable stiffness are essential tool in mechanobiology, allowing to investigate the effects of mechanical signals on cell behavior. A bottleneck that slows down the popularization of hydrogel formulations for mechanobiology is the assessment of their stiffness, typically requiring expensive and sophisticated methodologies in the domain of material science. Here we overcome such barriers offering the reader protocols to set-up and interpret two straightforward, low cost and high-throughput tools to measure hydrogel stiffness: static macroindentation and micropipette aspiration. We advanced on how to build up these tools and on the underlying theoretical modeling. Specifically, we validated our tools by comparing them with leading techniques used for measuring hydrogel stiffness (atomic force microscopy, uniaxial compression and rheometric analysis) with consistent results on PAA hydrogels or their modification. In so doing, we also took advantage of YAP/TAZ nuclear localization as biologically validated and sensitive readers of mechanosensing, all in all presenting a suite of biologically and theoretically proven protocols to be implemented in most biological laboratories to approach mechanobiology.

Abstract

Microenvironmental mechanical signals are fundamental regulators of cell behavior both in physiological and in pathological context, particularly in the induction and maintenance of tumorigenic properties. It is thus of utmost importance to experimentally recreate conditions that mimic the physical attributes of real tissues to study their impact on cell behavior and in particular on the induction of cancer stem cell (CSC) properties. Here we present protocols to investigate the role of mechanical stiffness on reprogramming of primary mammary gland cells into CSCs, including the synthesis of hydrogel substrates of the desired stiffness, the isolation and culture of primary differentiated normal cells derived from the human mammary gland, and the assessment of their CSC attributes after oncogene-mediated transformation., (© 2024.
