Tension Cell Stretching Bioreactor System

About Our Tension Systems

Flexcell® Tension Systems are patented, computer-regulated bioreactors that apply cyclic or static strain to cells cultured in vitro.

We designed Flexcell® Tension Systems to help investigators analyze biochemical changes in response to tensile load on a variety of cell culture applications, including muscle, lung, heart, vascular vessels, skin, tendon, ligament, cartilage, and bone.

Our Tension Systems work with UniFlex® (Uniaxial strain), BioFlex®, HT BioFlex® (Equibiaxial strain), Tissue Train® and CellSoft® BioFlex® culture plates.

How Our Tension Bioreactors Work

Our cell stretching bioreactor systems are great for the stimulation of cells in cell culture using mechanical strain. Using our pneumatic stretching protocol system instead of a motor-driven or electrical system allows you to avoid any confounding vibrational strain, or electronic (E), or magnetic fields (B).

What our customers say

“Cells were seeded on flexible silicone-bottom plates (Flexcell® Tension System) at a density of 3 × 105 cells per well. Pathologically elevated cyclic stretch increased the secretion of miR-27a, which was transferred from VSMCs to ECs via the VSMC-MPs, subsequently targeted GRK6, and induced EC proliferation. Locally decreasing miR-27a could be a novel therapeutic approach to attenuate the abnormal EC proliferation in hypertension.”

“A Flexcell® Compression Plus system was used to enable longer-term compression of multicellular aggregates (MCAs) in custom-designed hydrogel carriers. Results show changes in the expression of genes related to epithelial-mesenchymal transition as well as altered dispersal of compressed MCAs on collagen gels.”

“The study of fluid shear as a driving force for cell migration, i.e., "flowtaxis", and investigation of molecular mechanosensors governing such behavior (e.g., ROCK as tested in this study) may provide new and improved insights into the fundamental understanding of cell migration-based homeostasis. The flow regimens could be controlled by the peristaltic pump and the Osci-Flow device, which were governed by StreamSoft v. 4.1 software provided by Flexcell® International Corp.”
