Area of Science:

  • Cell Biology
  • Tumor Microenvironment Research
  • Angiogenesis Studies

Background:

  • The tumor microenvironment significantly impacts physiological and pathological events.
  • Cell-cell and cell-extracellular matrix interactions are crucial for cellular functions like differentiation, proliferation, and angiogenesis.
  • Tumor growth necessitates nutrient and oxygen supply via new blood vessels, making angiogenesis a critical process.

Purpose of the Study:

  • To review literature on the relationship between tumor and endothelial cells using spheroid models.
  • To explore the influence of the microenvironment on angiogenesis within a 3D context.
  • To categorize existing spheroid-based research for a clearer understanding of their applications.

Main Methods:

  • Literature review of studies involving tumor and endothelial cells cultured as spheroids.

  • Categorization of spheroid studies into three distinct classes: in vitro/in vivo, in vitro/monolayer co-culture, and organotypic tumor cultures.
  • Analysis of how these spheroid models facilitate the study of cell-cell interactions and microenvironmental effects.

    • Main Results:

    • Spheroid cultures provide a three-dimensional model to study tumor-endothelial cell interactions.
    • Different classifications of spheroid studies reveal varied approaches to investigating angiogenesis and microenvironment.
    • The reviewed studies demonstrate the applicability of spheroid models in analyzing complex biological phenomena.

    Conclusions:

    • Spheroid cell cultures are valuable for studying tumor-endothelial cell relationships and microenvironmental influences on angiogenesis.
    • These 3D models aid in analyzing physiological processes such as wound healing, extravasation, and intravasation.
    • The categorization provides a framework for future research utilizing spheroid models in cancer biology and related fields.
