Tumor Stroma

Molecular classification
Other
01

Overview

The tumor stroma refers to the non-malignant supportive tissue surrounding and infiltrating tumors, including fibroblasts, immune cells, blood vessels, and extracellular matrix. Targeting the tumor stroma with alpha particle emission is an emerging strategy in cancer therapy to disrupt the tumor microenvironment and inhibit tumor growth and metastasis.
