Figure 7From: Proteotypic classification of spontaneous and transgenic mammary neoplasmsSolid carcinoma from a mouse transgenic for Hras: expression of α-smooth muscle actin in carcinomas is restricted to stromal myofibroblasts and vascular smooth muscle fibers. A similar observation was made for carcinomas arising in mice transgenic for Neu (Erbb2) and Notch 4 and in most mice transgenic for SV40-TAg (not shown). Scale bar, 320 μm.Back to article page
