3D Cell Culture

Inquiry

Recently, 3D cell culture has gained more attention because it is closer to clinical tests compared with the 2D cell culture model. In this context, the advent of microfluidic chips provides 3D cell culture more possibilities. As an industry-leading CRO company, Creative Biolabs is dedicated to supporting 3D cell culture services by designing and developing microfluidic chips.

Introduction of 3D Cell Culture

Cell culture under the 3D model can better mimic the actual complex environment in vivo than the conventional 2D culture model, in terms of extracellular matrix components, cell-to-cell, and cell-to-matrix interaction. Compared with the 2D culture model, the results of drug screening under 3D mode are closer to clinical tests and can provide more realistic predictions for safety and risk assessment.

Microfluidic Chip and 3D Cell Culture

The emergence of the microfluidic chip technique has provided a miniaturized platform for 3D cell culture with low consumption, high cell spheroid formation efficiency, integrated devices, and better control to spheroid sizes and flows in spatial and temporal domains, which could mimic in vivo-like microenvironments with high precision and throughput. So far, a variety of different microfluidic methods have been developed to perform 3D cell culture for forming cell spheroids in microfluidic systems, which could be divided into three types which are hanging-drop, microstructure array, and droplet-based microfluidics.

Microfluidics-based 3D Cell Culture in Organoids

Microfluidics-based 3D cell culture systems are now emerging as platforms for more accurate and cost-effective drug development and testing as an avenue toward laboratory-grown tissue and organ replacements. A distinct subset of 3D cell culture, organoids are self-organized tissue systems derived from stem cells including induced pluripotent stem cells (iPSCs), embryonic stem cells (ESCs), and in vivo derived progenitor populations. They can reflect much of the complexity of the organ they model or present with certain aspects of the organ. They can be distinguished from organ-on-chip technology that relies on engineering-specific complexity or features into the system, such as distinct spatial separation of different cell types and/or extracellular matrices, in order to model a key organ or tissue function or subunit. An advantage of organoid cultures, compared to monolayer culture systems, is that it provides an environment allowing cell-cell interactions to be established, therefore mimicking the in vivo situation.
