Fig. 8From: White matter injury but not germinal matrix hemorrhage induces elevated osteopontin expression in human preterm brainsOPN expression in oligodendrocytes is not increased in response to white matter injury. Oligodendrocytes were stained for anti-Olig2 (red) and anti-OPN (green) along with DAPI nuclear counterstaining, and the number of double-labeled cells in the white matter was counted. (A-L) Representative immunofluorescence images from control (A–D), WMI (E–H), and GMH (I-L) cases (arrowhead: OPN-Olig2 double-labeled cells, star: OPN single-labeled cells). (M) Density of OPN+-Olig2+ cells. Scale bar = 25 µmBack to article page
