MedChemExpress a8301 sodium

a Overview of in vitro <t>A8301-mediated</t> TGF-β signal inhibition in BA-MBOs. Created in BioRender. Ayabe, H. (2025) https://BioRender.com/q1pk62z . b Representative plots and quantification of FACS of day 14 MBOs treated with A8301. Number of hybrid (pan-CK + /VIM + ), cholangiocyte (pan-CK + /VIM - ) and mesenchymal (pan-CK − /VIM + ) cells were quantified (Mean ± SD; n = 12 organoids). c Images of MBOs treated with A8301 captured before collection and after whole-mount immunostaining (CK19: red, CD31: green, VIM: white). Abundance of CK19 + structures (Mean ± SD; n = 9 organoids examined over 3 independent experiments) and size distribution of PBG-like structures were quantified ( n = 39-104 clusters examined over 3 independent experiments). d Immunostaining of ECAD (green), CK19 (red) and Nucleus (blue; DAPI) in MBOs treated with A8301. ECAD + cells in CK19 + cells in the field were quantified (Mean ± SD; n = 12 fields from 3 organoids). e Immunostaining of ZO1 (green), CK19 (red) and Nucleus (blue; DAPI) in MBO treated with A8301. ZO1 + cells in CK19 + cells per field were quantified (Mean ± SD; n = 12 fields from 3 organoids). f Alcian blue staining of MBOs treated with A8301. Mucin production was determined by ratio of Alcian Blue + areas in CK19 + (from separately examined immunofluorescence data) areas (Mean ± SD; n = 12 fields from 3 organoids). g Top enriched terms of MSigDB Hallmark 2020 , and GO , sets in serum proteins (reanalyzed from Lertudomphonwanit et al. ) upregulated in BA subjects ( n = 175 patients) vs age-matched normal controls ( n = 9). MF: Molecular Function, BP: Biological Process. h Heatmap of enriched proteins in the EMT pathway in MSigDB Hallmark 2020 sets. ( n = 9 NC and 175 BA subjects). i Serum TGF-β/Activin ligand levels represented by the relative fluorescent unit (RFU; Mean ± SD). ( n = 9 NC and 175 BA subjects). The p -values were shown in plots and were determined using one-way ANOVA with Tukey’s test ( b – f ) and two-tailed Welch’s t -test ( i ).
