ObjectiveTo summarize the research status and biological characteristics of stromal fibroblast in breast cancer. MethodsRelevant literatures about the breast cancer stromal fibroblasts published recently were collected and reviewed. ResultsIn addition to cancer cells, breast cancer included stromal cells. The fibroblasts were the major components of breast cancer stromal, which had significantly different biological characteristics from normal fibroblasts. The fibroblasts were characterized by α-SMA positive, p53 gene mutation, secretion of various cytokines or chemokines in addition to the production of collagen substances, involving in breast cancer growth, migration, invasion and metastasis through a variety of signaling pathways. ConclusionThe biological characteristics of stromal fibroblasts in breast cancer may reflect lesion properties, be of great importance to diagnosis and differential diagnosis and prognosis prediction of breast cancer. More attentions will be paid to the target therapy for stromal fibroblasts in breast cancer.
