Résumé détaillé
Three-dimensional tumor modeling represents a paradigm shift in cancer research, moving beyond traditional flat cell cultures to create more realistic representations of human tumors. This comprehensive review in Cell Stem Cell explores the latest advances in reconstructing tumor tissues using organoids and bioengineered niches.
Organoids are miniature, lab-grown versions of organs that maintain the cellular complexity and architecture of real tissues. When applied to cancer research, tumor organoids can preserve the genetic and phenotypic characteristics of patient tumors, making them invaluable for studying cancer biology and testing treatments.
Bioengineered niches take this concept further by recreating the tumor microenvironment, including supporting cells, blood vessels, and the extracellular matrix that surrounds tumors in the body. This approach provides unprecedented insights into how tumors grow, spread, and respond to treatments.
These 3D systems offer several advantages over traditional methods: they better predict drug responses, reduce the need for animal testing, and enable personalized treatment strategies. Researchers can test multiple therapies on patient-derived organoids to identify the most effective treatments before beginning clinical treatment.
The implications extend beyond cancer research to regenerative medicine and tissue engineering. However, challenges remain in standardizing these complex systems and ensuring they accurately represent the full spectrum of human tumor diversity.
