GFAP and nasopharyngeal carcinoma: An increase in GFAP means that the severity of gliosis increased; examination of the results of counting and quantitative analysis of this marker showed that the level of GFAP expression was lower in the group that transplanted NPCs than the CP group (Figure 12, GFAP, CP: (61.15 ± 11.04); CP + NPC: (15.59 ± 3.78); P<0.0001).
