Figure Lengend Snippet: Temporal progression and cellular composition of primary OPC cultures. Phase-contrast images illustrate OPC morphology at DIV1, DIV5, and DIV7 (A) . Quantification of OLIG2 + and MBP + cells across days in vitro (DIV1–DIV7), expressed as percentage of total DAPI + nuclei per field, is shown in (B) , while total DAPI + nuclei per field were quantified over time as an estimate of net cell number (C) . Representative immunofluorescence images at DIV7 display OLIG2 + or MBP + cells (green) with DAPI counterstaining (blue) (D) . Culture purity was evaluated at DIV7 by immunostaining for PDGFRα (green) together with microglial (IBA1; panel E , red) or astrocytic markers (GFAP; panel F , red). Representative fields are shown to illustrate residual non-oligodendroglial cells; quantitative analysis across multiple fields confirmed minimal microglial and astrocytic contamination (<1% of total DAPI + nuclei). Data represent mean ± SEM from seven independent cultures derived from pooled neonatal cortices. Scale bars: 50 μm (A,D) ; 100 μm (E,F) .
Article Snippet: The following primary antibodies were used to identify distinct stages of the oligodendrocyte lineage: platelet-derived growth factor receptor alpha (PDGFRα; rabbit monoclonal, clone D13C6 XP®, Alexa Fluor® 488–conjugated, Cell Signaling Technology, Cat. No. 8871, 1:200) for OPCs; Olig2 (goat polyclonal, R&D Systems, Cat. No. AF2418, 5–15 μg/mL) for oligodendroglial lineage cells; and myelin basic protein (MBP; rabbit monoclonal, clone D8X4Q XP®, Cell Signaling Technology, Cat. No. 78896, 1:50) for mature oligodendrocytes.
