Characterization of oligodendrocyte brain organoids
(A) Bright-field images showing the developmental stages of oligodendrocytes brain organoids overtime in vitro. Scale bar = 400 μm.
(B) Analysis of immunostaining of organoid sections at day 140 showing expression of astrocyte marker GFAP (gold). The section was counterstained with Hoechst 33342 (cyan). Scale bar = 200 μm.
(C) Immunostaining of organoid sections on day 140 showing expression of the mature myelinating oligodendrocyte marker MBP (gold). The section was counterstained with Hoechst 33342 (cyan). Scale bar = 200 μm.
(D) Schematic diagram showing the different morphologies of MBP positive cells across organoid developmental stages.
(E) Examples of organoids sections at day 140 double immune-stained for astrocyte marker GFAP (gold) and the mature myelinating oligodendrocyte marker MBP (pink). All sections were counterstained with Hoechst 33342 (cyan). Scale bar = 25 μm.
(F) Immunostaining of organoids sections on day 120 showing expression of the pan-oligodendroglia marker OLIG2 (pink). The sections were counterstained with Hoechst 33342 (cyan). Scale bar = 200 μm. Zoomed images scale bar = 20 μm.
