Selective expression of Secisbp2l in OLs during differentiation stage. A, B, ISH revealed that Secisbp2l, but not Secisbp2, is expressed in the white matter of spinal cord from E18.5 to P15. Secisbp2l+ cells are represented by arrows. C, SECISBP2L is co-localized with CC1 and NKX2-2 (arrows), but not with Pdgfra (arrowheads) and GFAP. Immunofluorescent staining (IF) was performed on spinal cord transverse sections at P7 for all markers except for Pdgfra, which is pseudo-colored from ISH image. D, Relative ratio of SECISBP2L and CC1-positive cells. E, Co-labeling of DIO2 with CC1 in P7 spinal cord (represented by arrows). F, Co-labeling of SECISBP2L with CC1 in cortex (CTX), corpus callosum (CC), and cerebellum (CB) at P15. Double positive cells appear as white (arrows).
