Our lab is using Corning Matrigel matrix to co-culture cells in 3D on a microfluidic chip. I read that we should be using a thick layer of Matrigel matrix, but I’ve noticed that the amount of Matrigel matrix keeps going down each day and I need to add more. Do you have any recommendations so I can avoid having to add Matrigel matrix or should I be adding something else instead?


Combining microfluidics and extracellular matrices (ECM) has shown to be a promising system to create more in vivo-like 3D environments. Some publications have shown different methods to craft such environments. For example:

Understanding the biophysical cues of the 3D environment such as topography, stiffness, viscosity and porosity have shown to be important to mimic the in vivo environment. Modulating and tuning the tensile strength of the Matrigel matrix gel in a 3D environment may be beneficial to provide softer or stiffer gels to suit application need. Empirical studies may show that a stiffer gel (higher protein concentration), may reduce dilution of the gel caused by the flow in the microfluidic chip.

As we keep learning about these techniques and methods, we recommend you reach out to our global scientific support team to help you find the right solution for your work.
