QC immunostaining of young midbrain organoids for neuronal and DN markers
(A and B) IF staining of WA01 TH midbrain neurons for TH (green) and RFP (red) in (a) cryosection of a D20 organoid; (b) D21 dissociated neurons. The nuclei are counterstained with Hoechst (blue).
(C and D) IF staining of WA01 TH midbrain neurons for TUBB3 (green) and RFP (red) in (c) cryosection of a D20 organoid; (d) D21 dissociated neurons. The nuclei are counterstained with Hoechst (blue).
(E) Quantification of D21 TH+ cells as a percentage of total cells in B and similar images (n=50 per replicate). Error bars represent SEM.
(F) Quantification of D21 TH+ cells (as denoted by RFP staining for the TH-TdTomato reporter) as a percentage of TUBB3+ cells in D and similar images (n=35 per replicate). Error bars represent SEM.
All scale bars: 100 μm.
