Fig. 4From: Molecular pathological expression in malignant gliomas resected by fluorescein sodium-guiding under the YELLOW 560 nm surgical microscope filterCase16. a–c The biopsies obtained from Fig. 1b (a), stained by HE X200, GFAP X200, and Ki-67 X200, respectively. d–f Biopsies obtained from Fig. 1d (b), stained by HE X200, GFAP X200, and Ki-67 X200, respectively. a GBM cell nuclear split pleomorphism and was accompanied by a large number of vascular distributions. b Lighter color with GFAP staining, which was caused by lesser cytoplasm. c Ki-67 LI was 45%. d Brain tissue infiltration by tumor cells, nuclear atypia was uncommon as shown in a. e Deeper color with GFAP staining, which was caused by full cytoplasm. f Ki-67 LI was 25%Back to article page
