Figure 1From: Dysregulated angiogenesis in B-chronic lymphocytic leukemia: Morphologic, immunohistochemical, and flow cytometric evidenceIncreased Microvessel Density in CLL vs Controls. Microvessel density was highest at the periphery of focal infiltrates. This is a case of CLL (left panel) with nodular lymphoid infiltrates. The image shows an increase in CD34+ microvessels at the leading edge of an infiltrate. In the control tissue (right panel), the microvessel density is somewhat less.Back to article page
