Transplantation of human organoids into mouse diminishes off-target cells. t-SNE plots of organoids in prolonged in vitro culture reveal cell clusters in a D32 and b D51 organoids similar to clusters from D29 organoids. c Transplanted and vascularized organoid at D51. IF staining shows human podocytes (anti-human NPHS1 antibody) at the outer perimeter and mouse endothelial cells (anti-mouse Plvap antibody) lining the internal perimeter of a glomerular structure. Gray, human and mouse nuclei (DAPI). d Dotplots indicating ligand and receptor pairs involved in putative cross-talk between human podocytes and mouse endothelial cells of transplanted organoids. e Violin plots of expression levels for KLF6 and HES1 in the distal MAL+ cluster from D29, D32 and D51 organoids grown in vitro, compared to D32 transplanted organoids. f Violin plots demonstrate that PMEL+ melanoma cells and SOX2+ neuronal cells were diminished after transplantation. MYOG+ muscle cells and STMN2+ neuron-like cells persisted. g Random Forest Classifier shows the relation of cell clusters in transplant organoids compared to organoids grown in vitro. Melanoma and SOX2+ neuronal precursor cells are not detected in D32 transplant organoids. h IF staining validation for SOX2 (green) in D32 control organoids compared to diminished abundance in D32 transplanted organoids. Human and mouse nuclei (DAPI, gray).
