Introduction to Mechanobiology: Cellular Forces and Mechanotransduction

Biology is not just about chemical signals; physical forces play a critical role in shaping how cells grow, move, and function. Understanding mechanobiology is essential for unlocking new frontiers in tissue engineering, oncology, and regenerative medicine. This text-based course guides you through the foundational principles of how cells sense, respond to, and generate mechanical forces. You will transition from learning basic cell structures to understanding complex mechanotransduction pathways and the physical properties of living tissues. What you'll learn: - Understand the fundamental physical forces and mechanical properties that govern cellular environments. - Explore how cells sense mechanical cues through specialized receptors and convert them into biochemical signals. - Analyze the role of the cytoskeleton in force generation, cell motility, and structural integrity. - Examine modern mechanotransduction pathways, including the roles of Piezo channels and YAP/TAZ signaling. - Learn the core concepts behind modern measurement techniques, such as traction force microscopy and atomic force microscopy. - Apply mechanobiological concepts to understand disease progression, such as cancer metastasis and tissue fibrosis. The course begins with essential terminology and the mechanical properties of extracellular matrices before moving into cellular mechanics, force transmission, and modern research methodologies. You will progress logically through written explanations and conceptual exercises designed to solidify your understanding. This course is designed for beginners, students, and researchers in biology, engineering, or physics who want to learn the physical side of life sciences without any prior background in mechanobiology.
