Cyclic mechanical stretching
WebAug 28, 2001 · Mechanical stretch increased the secretion pattern of the growth factors. The increased concentrations of TGF-β, bFGF and PDGF after cyclical mechanical stretching may have a positive influence on tendon and ligament healing through stimulation of cell proliferation, differentiation and matrix formation. WebEvidence suggests that cellular responses to mechanical stimuli depend specifically on the type of stimuli imposed. For example, when subjected to fluid shear stress, endothelial cells align along the flow direction. In contrast, in response to cyclic stretching, cells align away from the stretching direction.

WebMar 17, 2024 · The cyclic mechanical stretch model of NP cells in vitro was established using a cell stretching instrument (Mechano Culture FX2, Cell Scale, Canada) that was controlled by a computer. The NP cells were seeded into a sixteen-well flexible-bottom Silicone Plate (Cell Scale, Canada) at a density of cells/200 μ L in the culture medium … WebMechanotransduction is the process through which mechanical stimulation triggers proliferation, apoptosis, and extracellular matrix synthesis, among other cell activities. Regarding that aspect, the effect of in vitro stimulations such as compression, stretching, bending or fluid shear stress loading modalities have been extensively studied.
