Mesenchymal Stem Cells Relevance in Multicellular Bioengineered 3D In Vitro Tumor Models

Area of Science:

• Oncology
• Stem Cell Biology
• Biotechnology

Background:

• Three-dimensional (3D) in vitro tumor models are emerging as superior alternatives to 2D cultures for cancer research.
• These models aim to replicate the complex in vivo tumor microenvironment and its cellular components.
• Mesenchymal stem cells (MSCs) significantly influence cancer progression, acting as both tumor suppressors and promoters.

Purpose of the Study:

• To review the biological impact of various MSCs within the tumor microenvironment.
• To highlight recent advancements in engineering 3D co-culture models of MSCs and cancer cells.
• To discuss the parameters, challenges, and future directions for these advanced in vitro platforms.

Main Methods:

• Literature review of studies engineering 3D co-cultures of MSCs and cancer cells.
• Analysis of MSC-cancer cell crosstalk within the tumor microenvironment.
• Focus on the set-up parameters and challenges of 3D co-culture systems.

Main Results:

• MSCs play a complex, multi-modulatory role in the tumor microenvironment.
• Engineered 3D MSCs-cancer cell co-cultures serve as advanced platforms for therapy testing.
• Understanding MSC-cancer cell interactions is key to developing effective 3D in vitro models.

Conclusions:

• 3D co-culture models incorporating MSCs offer a more realistic in vitro representation of the tumor niche.
• These models are essential for discovering and validating new cancer treatments.
• Further research into MSC-cancer crosstalk will drive the development of next-generation cancer models.
