Immunofluorescence staining was performed to examine the αvβ3 and CD31 expression levels in tumour tissues from the xenografted gliomas in the SG and P-CP-PLGA group on days 0.5, 2, and 4; as shown in Figure 6, compared with the P-CP-PLGA seed group, the quantitation of the glioma anti-αvβ3 immunofluorescence levels in the SG revealed a 1.37-fold (±0.15) mean increase (±SD) on day 0.5 and 0.74-fold (±0.22) and 0.15-fold (±0.05) decreases on days 2 and 4, respectively. The gene discussed is CP; the disease is neoplasm.
