doi: 10.64898/2026.03.30.715210

Figure Lengend Snippet: a , Schematic illustration for identification of Creld1-interacting protein in DRGs by immunoprecipitation and mass spectrometry. b , Representative Na v currents in DRG neurons from control and sgCreld1 mice. c , Representative Na v currents recorded in DRG neurons derived from WT and cKO mice. d , Scatterplot of normalized mRNA levels of the indicated Na v isoforms expressed in WT and cKO DRGs. e , Immunofluorescent staining of either Na v 1.7 and TUBB3 from the indicated DRG sections. Scale bar, 20 μm. f , Total density of Na v 1.7 expression of DRG neurons from WT (389 cells) and cKO (252 cells). g , Immunofluorescent staining of endogenous Creld1 and Na v 1.7 in DRG neurons after 36 h in culture using the anti-Creld1, anti-Na v 1.7 and anti-TUBB3 antibody. Scale bars, 100 μm (top); 5 μm (bottom). h , Pearson’s co-localization efficiency analysis for Na v 1.7 and Creld1 located in DRG neurons after 36 h in culture. The white circle illustrates the region of interest (ROI) used for analyzing the immunofluorescence staining of Na v 1.7 and Creld1. Each dot represents an individual cell (17 cells in total).

Article Title: The RNA and protein landscapes of mouse brain organoids

doi: 10.64898/2026.03.13.711293

Figure Lengend Snippet: (A) Schematic timeline of brain organoids generation from mESCs. mESCs and brain organoids developed for 7, 14 and 21 days were profiled by transcriptomics and proteomics. Part of the figure was created with Biorender. (B) Immunostaining of mESCs-derived brain organoids. Cultures of mESCs were stained with NANOG (green), POU5F1/OCT4 (red), and nuclei with DAPI (blue). Scale bars: 10 µm. (C) Organoid cryosections were stained with NESTIN and PAX6 (at day 7), ELAVL3 and TBR1 (at day 14), and TUBB3 and GFAP (at day 21). Scale bars: 100 µm. (D) PCA showing the distribution of the transcriptomes of mESCs, brain organoids (at days 7, 14, and 21), and NBB samples. (E) Venn diagram showing the overlapping upregulated and downregulated genes between D21 organoids and NBB, both compared to mESCs. (F) Histograms of enriched GO terms in NBB vs ESCs and D21 organoids vs ESCs performed on upregulated genes (black and grey bars) and on downregulated genes (red and light red bars) determined using DAVID. For each term category (Cellular component, molecular function, and biological process), the five highest enriched terms in each gene list are shown.
