Figure 4From: Myofibroblastic stromal reaction and lymph node status in invasive breast carcinoma: possible role of the TGF-β1/TGF-βR1 pathway CD34 and SMA expression in breast fibrocytes cell line before and after treatment by TGF-ß1. A: absence of an expression of CD34 within untreated breast fibrocytes (X200). B and C: presence of a significant proportion of SMA-positive myofibroblasts after treatment of breast fibrocytes by TGF-ß1 (B:X40; C:X400).Back to article page
