What is the Developmental Origin of Parafollicular Cells?
The developmental origin of parafollicular cells is the neural crest, a group of cells that emerge from the embryonic ectoderm and migrate to various parts of the body. During embryogenesis, neural crest cells migrate to the ultimobranchial bodies, which later fuse with the developing thyroid gland. This fusion integrates the parafollicular cells into the thyroid tissue.
