Research on the prognosis of different types of microvessels in bladder transitional cell carcinoma

Figure 1 Two different types of microvessels were observed in bladder transitional cell carcinoma. A: CD34-stained pictures clearly reveal differentiated blood vessels in bladder transitional cell carcinoma (× 400); B: Other blood vessels are stained with CD31 in the same position. As shown by the arrow position, undifferentiated blood vessels are not stained by the CD34 monoclonal antibody (× 400); C: Smooth muscle actin staining confirms that peripheral cells cover the blood vessels stained by CD34, but no peripheral cells cover the undifferentiated blood vessels in Figure 1B (× 400).
