Special Issue Information

Dear Colleagues,

This Special Issue, titled “Biomechanics and Mechanobiology in Cell and Tissue Engineering”, encompasses a comprehensive exploration of the diverse applications and implications of mechanobiology in various fields, including biology, medicine, and engineering. This Special Issue aims to delve into how physical forces influence biological processes and the mechanical properties that impact living organisms. This collection of original research articles and reviews focuses on the incorporation of mechanical cues into scaffold design, culture environments, and the development of innovative therapies and diagnostics. We welcome submissions from all therapeutic areas of tissue engineering, including, but not limited to, the following: vascular disease, cardiovascular disease, neurobiology and neuroengineering, stem cell mechanobiology, cancer mechanobiology, osteoarthritis, and bone mechanobiology.

Furthermore, we aim to highlight the crucial role played by mechanobiology research in bone and articular cartilage for the treatment of conditions such as osteoporosis and osteoarthritis. Additionally, this Special Issue emphasizes the significance of understanding how mechanical forces affect neuronal development, axon guidance, and neural regeneration for addressing neurodegenerative diseases and developing neural implants and tissue engineering approaches for spinal cord injuries. Furthermore, it underscores the influence of mechanobiology on drug discovery efforts, the identification of mechanosensitive drug targets, and the development of screening assays that incorporate mechanical cues. Overall, the interdisciplinary approach of this Special Issue means that it will provide valuable insights into the complex interactions between mechanical forces and biological systems, leading to advancements in healthcare, tissue engineering, and overall understanding of life processes.

The cervical spine ligaments, including the anterior longitudinal ligament (ALL) and posterior longitudinal ligament (PLL), play a key role in maintaining spinal stability by limiting excessive movements. This study investigates how ageing affects the mechanical properties of these ligaments. We analysed 33 samples from 12 human cervical spines (15 ALL, 18 PLL), averaging data from the same donors for independent analysis, resulting in 18 final samples (8 ALL, 10 PLL). To explore age-related changes, we classified the samples into two groups—below and above 50 years old—aligning with the peak incidence of major musculoskeletal disorders. The investigation concentrated on the effects of age on four mechanical parameters of the uniaxial stress–stretch curve: initial tangent stiffness (E0), maximum tangent stiffness (Em), ultimate stress (Pu) and ultimate stretch (λu). When the age effect is neglected, then the behaviours of both the ALL and PLL appeared similar. However, when introducing age as a variable into the context of the ALL and PLL, statistically significant differences became evident. The findings underscored a reduction in maximum tangent stiffness (p-value = 0.0147), ultimate stress (p-value = 0.0009), and ultimate stretch (p-value = 0.0024) when the ALL and PLL were grouped under and above 50 years as a consequence of ageing.
