- Differential tissue stiffness of body column facilitates locomotion of Hydra on solid substrates
Summary: The Hydra somersault is facilitated by differential stiffness contributed by the organization of collagen fibers in the extracellular matrix. The extracellular matrix assumes a pseudo-skeletal property important for locomotion.
- Passive muscle tension increases in proportion to intramuscular fluid volume
Summary: Passive tension in skeletal muscle increases in proportion to tissue fluid volume, suggesting that natural fluctuations in water content may influence muscle performance in vivo.
- microRNA-29b knocks down collagen type I production in cultured rainbow trout (Oncorhynchus mykiss) cardiac fibroblasts
Summary: Increased expression of microRNA-29b decreases collagen type I synthesis in rainbow trout (Oncorhynchus mykiss) cardiac fibroblasts, suggesting that this microRNA could play a role in temperature-induced changes in collagen content in the trout heart.
- Transforming growth factor-β1 induces differentiation of rainbow trout (Oncorhynchus mykiss) cardiac fibroblasts into myofibroblasts
Summary: Repeated treatment of cultured trout cardiac fibroblasts with physiological concentrations of human TGF1-β induces cells to transform into myofibroblasts, as well as stimulating their capacity to turnover extracellular collagen.
- Functional morphology of the Alligator mississippiensis larynx with implications for vocal production
Summary: Morphology and laryngeal biomechanics are used to model the boundaries of the alligator's available acoustic space.
