Experimental study of the origin of the parathyroid glands.
The origin of the parathyroid glands was investigated in chick embryos (Gallus domesticus). Pieces of the third branchial arch were grafted, and its ectodermal layer formed a new structure (parathyroid III), which became separated from the placodial ectoderm. This structure continued to develop until, together with neural crest cells which gave rise to the mesenchyme, it formed a distinct parathyroid III gland by stage 28 of Hamburger and Hamilton.
