Furthermore, within the CH group, a positive correlation was observed between ventricular volume and GFAP signal measured by area (r = 0.653, p < 0.05, Figure 2H) and fluorescence intensity (r = 0.605, p < 0.05, Figure 2I), as well as Iba1 signal measured by area in the basal cistern (r = 0.669, p < 0.05, Figure 2J). Here, GFAP is linked to cyclic hematopoiesis.
