| Caption | Spectrum of vascular tumors in livers of Vhltm1.1Jae/Vhl+ (VHL1/+) mice and histological comparison of Vhltm1.1Jae/Vhl+ vascular lesions with vascular lesions found in mice with hepatocyte specific ablation of Vhl (Vhltm1Jae/Vhltm1Jae Speer6-ps1Tg(Alb-cre)21Mgn/0; Albumin-cre mutant). Panel A. Formalin fixed livers of Vhltm1.1Jae/Vhl+ mice. (a) Gross photograph of a large cavernous hemangioma of the right liver lobe. (b) Gross photograph of a small vascular lesion in unsectioned liver. (c) Liver from Panel A(b) sectioned. The vascular lesion is indicated by the arrow. (d) Example of a medium-sized hemangioma of the right liver lobe. (e) Paraffin section of a cavernous hemangioma stained with H&E. The arrows point to cords of normal-appearing hepatocytes and stars depict vascular cavities. (f) CD31 immunostain of endothelial cells lining a large cavity. Panel B. Comparison of vascular lesions of Vhltm1.1Jae/Vhl+ mice with Vhltm1Jae/Vhltm1Jae Speer6-ps1Tg(Alb-cre)21Mgn/0 mice, at low-power and high-power magnification. Stars indicate endothelium-lined vascular spaces, straight arrows point to lipid-containing hepatocytes, and dashed arrows indicate small vascular spaces/vessels. Panel C. Analysis of hepatocellular lipid vacuoles by electron microscopy, and PCNA-staining of Vhltm1.1Jae/Vhl+ vascluar lesions. Shown on the left is a hepatocyte containing multiple lipid vaculoes (arrows), the appearance of which is consistent with neutral lipid (triglyceride). Shown on the right are PCNA-positive cells (arrows) in a typical vascular lesion; small vessels are marked with stars. Panel D. Foci of increased vascularization in Vhltm1.1Jae/Vhl+ and Vhltm1Jae/Vhltm1Jae Speer6-ps1Tg(Alb-cre)21Mgn/0 livers and CD31 immunostain of small vessels (arrows). | ||||||||
