Cells freshly isolated from a human thymus and stained for epithelial cell markers in different colors (small cells in blue, red and green) and human pancreatic organoids growing in culture (large spheres in the centre). From Paola Bonfanti's Epithelial Stem Cell Biology & Regenerative Medicine Laboratory.
Intro
