What are carcinoma-associated fibroblasts?
Carcinoma-associated fibroblasts (CAFs) are fibroblasts found in the tumor microenvironment that contribute to tumor progression.
How are CAFs generated in this study?
CAFs are generated from primary human mammary fibroblasts through a coimplantation tumor xenograft model.
What role do myofibroblasts play in tumors?
Myofibroblasts are activated fibroblasts that contribute to the tumor microenvironment and promote tumor progression.
What is the significance of the stroma in cancer?
The stroma provides structural support and influences tumor behavior, making it a critical component in cancer biology.
What techniques are used to immortalize fibroblasts?
Fibroblasts are immortalized through viral transduction, allowing for long-term culture and study.
Why is GFP expression important in this study?
GFP expression allows for the visualization and tracking of CAFs in experimental models.
