3D Cell Culture

3D Cell Culture

3D cell culture enables cells to grow, proliferate and migrate in a three-dimensional space to form a three-dimensional cell-cell or cell carrier complex, so as to better simulate the growth environment of cells in vivo. 3D cell culture has the advantages of approaching all aspects of human tissue, such as structure, cell tissue, interaction between cells and cell matrix, and more physiologically related diffusion characteristics. Therefore, 3D models are used in drug screening and cancer research.

3D Cell Culture

Currently, 3D cell culture is divided into scaffold and scaffold free three-dimensional culture technology. 3D cells cultured on scaffolds are inexpensive and simple to operate. Scaffold materials include collagen and hydrogel. 3D cell culture without scaffolds is mainly carried out by physical methods, mainly including microcarriers, magnetic levitation, hanging drop plates, etc. These types of operations are complicated and costly.

Characteristics of Different 3D Cell Culture Methods

Type of 3D system Description of cell culture Advantages
Suspension cultures on non-adherent plates Single cells are seeded on non-adherent plates with medium
3D structures can be observed after 3 days of culture
Simplicity, easiness and speed of conducting culture
Bacterial plates or non-adherent culture plates can be used but only for some cell lines
Cells can be easily extracted from the medium and used for further experiments
Cultures in concentrated medium or in gel-like substances Single cells grow in medium containing substances with gelling properties: i) dissolved low-melting agarose with cell medium is poured on plate and incubated until solidifying to obtain the first, lower layer; the top layer consisting of agarose and the medium with single cells is added; ii) the cells are flooded in Matrigel (multiprotein hydrogel)
3D structures can be observed after 7 days of culture
Soft agar allows studying both the growth of a single cell regardless of attachment and the phenomenon of escape from anoikis
Cells can be easily recovered for further analysis
Cells have three-dimensional interactions with the local environment and form tissue-like structures
Used to study the aggressiveness of the cells and their potential for metastasis
Cultures on scaffold The cells can migrate among fibres and attach to the scaffold, made of biodegradable material such as silk, collagen, laminin, alginate, and fill the space among fibres, grow and divide System is compatible with commercially available functional tests, as well as with DNA/RNA and protein isolation kits
Easy to prepare for immunohistochemical analysis

3D Cell Culture and Imaging Analysis Workflow

Although imaging analysis of 3D cell models has become an extremely attractive research tool for understanding complex biology, 3D cell image acquisition and analysis methods are still important factors hindering its development. CD BioSciences can generate more predictive data by image acquisition and analysis of 3D cell models through high connotation imaging (HCI) system. The following is the general flow of 3D cell culture and imaging analysis.

3D Cell Culture and Imaging Analysis

Seven main steps transform images into quantitative information to support experimental conclusions.

Choose cell lines that allow you to closely mimic the in vivo state
Selecting the right culture matrix
Culture specialized 3D cell models
Treatment with test compounds
Analyze by high-content imaging software
Acquire 3D cell image
Stain for markers
