We describe the expression of Foxp1 and Foxp2 during craniofacial development.
Foxp1 was expressed in the developing muscle, bone, and tendon of the jaw.
Foxp2 was expressed in a subset of bone and tendon progenitors.
Both Foxp1 and Foxp2 were expressed in the temporomandibular joint.
This is the first report on the expression of Foxp1 and Foxp2 in the face.
