Fig. 2From: Primary explants of the postnatal thymus allow the expansion of clonogenic thymic epithelial cells that constitute thymospheresClonogenic TECs derived from thymic explants restore the four subsets of medullary TECs and most of these cells highly express CD80. A Most cells derived from primary explants cultured in functionalized coverslips express the classic epithelial marker EpCAM (CD326). B The four subsets of medullary TECs were present in the epithelial cell colonies derived from thymic explants. C Most cells derived from explants highly express CD80. A–C scale bar: 20 µm D = 100 n = 2. DIC = differential interference contrast, mTECs = medullary thymic epithelial cellsBack to article page
