Hidden keys in stroma: Unlocking the tumor progression.

Area of Science:

• Oncology
• Cell Biology
• Cancer Research

Background:

• Malignancy arises from a complex tumor-host microenvironment where host cells influence neoplastic cell growth.
• Cancer invasion involves the disruption of tissue boundaries, facilitated by specific stromal cells.
• Tumor cells can modify the stroma, and stromal cells, in turn, can drive cancer progression.

Purpose of the Study:

• To compare the roles of cancer-associated fibroblasts (CAFs), tumor-associated macrophages (TAMs), and endothelial cells (ECs) in the tumor microenvironment.
• To emphasize the contribution of these stromal cells to tumor invasiveness.
• To review and summarize recent literature (last 10 years) on stromal cells and their role in cancer.

Main Methods:

• Literature review and collation of existing studies.
• Focus on experimental studies and clinical trials.
• Data sourced from PubMed Central indexed journals.

Main Results:

• Stromal cells like CAFs, TAMs, and ECs are key players in promoting cancer progression and invasion.
• These cells interact with tumor cells, influencing the tumor microenvironment and facilitating malignancy.
• The review synthesizes findings on how these interactions contribute to invasive phenotypes.

Conclusions:

• CAFs, TAMs, and ECs are critical components of the tumor microenvironment that actively promote cancer invasion.
• Understanding these stromal cell roles is vital for developing targeted cancer therapies.
• Further research into these interactions can offer new therapeutic strategies against invasive malignancies.
