a A microscopic image of a typical HES3 NKX2.5-eGFP-derived HFO (green: NKX2.5-eGFP, blue: DAPI) shows the characteristic layers IC, ML, and OL, scalebar is 500 μm. b A detailed sketch of a cross sectional front view shows different characteristic features of the organoid as indicated. c A side view of an HFO schematically shows the distinct layers IC, ML, and OL. The sketches in (b, c) are adapted from ref. 21.
