Figure 1. The ontology of cervical thymi and their dependence on parathyroid organogenesis.

Figure 1

(a) Schematic of the possible origins of the cervical thymus. Red indicates either parathyroids (PT) or parathyroid-derived cervical thymi (pCT); blue indicates thoracic thymus (TT) and thoracic thymus-derived cervical thymi (tCT); white indicates nonthymus and non-parathyroid origin for cervical thymi (CT). (b) Cervical thymus detected on transverse section of E16.5 Foxn1::EGPF transgenic embryo (green, GFP; blue, DAPI). (c) Occurrence of cervical thymus begins at E15 embryonic stage; frequency increases with development until birth (n≥10 for each time point listed), (Error bars represent SEM, Scale bar=50μm).
