3D bioprinting for reconstituting the cancer microenvironment

Area of Science:

• Biomedical Engineering
• Cancer Research
• Tissue Engineering

Background:

• The tumor microenvironment is complex and dynamic, challenging study using traditional 2D cell cultures.
• Existing 3D in vitro models like spheroids and cancer-on-a-chip devices offer improvements but lack precise control over multicellular organization.
• Understanding the biochemical and biophysical cues in cancer progression requires more sophisticated models.

Purpose of the Study:

• To review the applications of 3D bioprinting in creating physiologically relevant cancer microenvironment models.
• To discuss the potential of 3D bioprinting for prescreening cancer immunotherapies.
• To provide an overview of current bioprinted cancer models.

Main Methods:

• Review of existing literature on 3D bioprinting techniques applied to cancer modeling.
• Analysis of how 3D bioprinting enables precise control over cell positioning and perfusable networks.
• Discussion of the advantages of 3D bioprinting over conventional 2D and other 3D in vitro models.

Main Results:

• 3D bioprinting allows for high-throughput recapitulation of complex, dynamic cancer microenvironments.
• This technology facilitates the precise spatial organization of multiple cell types within engineered tissues.
• Bioprinted models show promise for dissecting cancer initiation, progression, and response to therapy.

Conclusions:

• 3D bioprinting represents a significant advancement in creating in vitro cancer models that closely mimic the in vivo tumor microenvironment.
• These advanced models are valuable tools for fundamental cancer research and for prescreening novel immunotherapies.
• Further development in 3D bioprinting will enhance our ability to study and treat cancer.
