27 Aug A microfluidic platform for generation of 3D spheroids using a hydrogel scaffold
Cells live in a 3D environment and in-vitro studies that recapitulate this 3D environment can potentially better mimic the in-vivo conditions. Microfluidic chips and in particular droplet microfluidics have been promising in recent years for creating such 3D cell populations. For this week’s research highlight, we have selected a recent paper published in ACS Biomaterials Science in which a PDMS-based droplet microfluidic generator was employed to encapsulate cells in thiol–acrylate (TA) hydrogel scaffold droplets. The droplets were then trapped in a microfluidic device for on-chip polymerization and incubation.
“The findings from this study highlight an alternative approach to generate 3D spheroids incorporating an easy-to-use, inexpensive scaffold that can be used for high-throughput spheroid generation and drug screening. The growth and viability of MCF7 spheroids were maintained for 7 days by continuous media flow generated using a customized gravity-driven media flow system to eliminate the need for syringe pumps.“, the authors explained.
“In the future, this system can be used for on-chip interrogation and evaluation of different biological systems such as the interaction between different types of cells and their effect on drug resistance.“, the authors explained.
