Parathyroid position in mouse embryo

Figure 1. The position of the parathyroid glands are seen in the mouse embryo.

Mig12 expression analysis during embryonic development. (A) Whole mount in situ hybridization on E11.5 mouse embryo showing expression in the central nervous system and in the developing limbs (blue signal, a). Coronal and sagittal sections of E14.5 entire mouse embryos (white signal) (b). (B) Details of coronal (a, b, c, d, h) and sagittal (e, f, g, i) sections of E14.5 mouse embryos. Strong Mig12 expression (red signal) is observed in isthmal (a), pontine (a, b, e) and medulla oblongata (c) neuroepithelia, and it is maintained throughout the entire region of the spinal cord central canal (d). Expression is also observed in dorsal root ganglia (d). Mig12 transcript is detected in the telencephalon at the level of the ventricular zone (f). Signal is also present in other organs: in the perichondrium of the digits (g); in the thyroid (th) and parathyroid (pth) glands (h), and in the phallic part of the urogenital sinus (i). Abbreviations: CB, cerebellum; ccn, central canal neuroepithelium; drg, dorsal root ganglia; IS, isthmus; isn, isthmal neuroepithelium; M, medulla oblongata; mn, medulla oblongata neuroepithelium; P, pons; pc, perichondrium; pnn, pontine neuroepithelium; pth, parathyroid glands; SC, spinal cord; T, telencephalon; th, thyroid gland; us, urogenital sinus; vz, ventricular zone.
