TS17: 3rd branchial arch	Present	Regionally restricted	9C	Crabp1 was expressed in a stream of cells that appeared to transverse the third, fourth and developing sixth branchial arches, entering the aortic sac and outflow tract in a similar fasion to Pax3.
TS17: 4th branchial arch	Present	Regionally restricted	9C	Crabp1 was expressed in a stream of cells that appeared to transverse the third, fourth and developing sixth branchial arches, entering the aortic sac and outflow tract in a similar fasion to Pax3.
TS17: 6th branchial arch	Present	Regionally restricted	9C	Crabp1 was expressed in a stream of cells that appeared to transverse the third, fourth and developing sixth branchial arches, entering the aortic sac and outflow tract in a similar fasion to Pax3.
TS17: outflow tract	Present	Regionally restricted	9C	Crabp1 was expressed in a stream of cells that appeared to transverse the third, fourth and developing sixth branchial arches, entering the aortic sac and outflow tract in a similar fasion to Pax3.
