Solutions for Strex Cell Stretch Systems

Adhesion to the stretch chamber was confirmed under the microscope before the stretch stimulus was initiated, yet after the stretching, the cells were no longer adhered. What could have caused the cells to detach from the chamber surface?
There are three possible causes: 1. Cell density The cell concentration of the culture may be too dense. Generally speaking, over-confluence will cause the...

Cells seeded onto the stretch chamber sometimes aggregate at the center of the chamber. Is there any technique to avoid this aggregation?
Cells may be migrating toward the center of the stretch chamber due to the vibration of the incubator. If that is the issue, seed the cells normally, then a...

Are rounded cells difficult to be stretched even though they adhere to the chamber?
Rounded cells are generally more difficult to be stretched in comparison with flat-shaped cells.

What is the longest period that the stretching stimulus can be applied using the Strex cell stretch device?
Cells in the incubator can be stretched for a period of two weeks. However, in these long-term experiments, the culture fluid has to be replaced at 2-3 day ...

What is the optimal cell count to be placed on the Strex stretch chamber?
In general, 200,000 cells / chamber (4 mL of culture medium) is proper from our experience.

At what temperature should coating Strex cell stretch chambers be performed?
We recommend coating Strex cell stretch chambers with the extracellular matrix at room temperature.

We are planning an experiment using neurons. Is It okay to coat them with laminin?
We do not foresee any problems with laminin coating, but unfortunately we do not have any experience using laminin coating.

What density of cells is adequate when we put them on Strex stretch chambers?
As a general guide, we say that the cells of 5 × 104 cm2 are adequate. However, this can vary depending on experimental parameters.

Do you have any movies of cells recorded in time-lapse capturing during Strex cell stretching?
Unfortunately no movie is available. Please refer to the following paper for photos of fluorescent images of GFP-actin transferred cells in the stretched st...
