KRT8 and neoplasm: The upper images in Fig. 6D show a representative example of control tumor-derived organoids, exhibiting high levels of CK14 and low levels of CK8/18, while miR-203-treated tumor-derived organoids (middle images) shifted the cytokeratins expression profile, being the CK8/18 the most predominant and CK14 becoming much less represented, almost absent.
