title: Experimental study of the origin of the parathyroid glands.
abstract: 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.
