Antibody:

anti-Pbx1b

Structure	Level	Pattern	Image	Note
TS14: future hindbrain neural crest	Present		3A	Expressed in all cells of the hindbrain, including the premigratory neural crest cells at the extreme dorsal tip of the neural tube (the neuroectodermal junction).
TS14: future hindbrain	Present	Widespread	3A
TS14: paraxial mesenchyme	Present		3A

Structure	Level	Pattern	Image	Note
TS15: future hindbrain neural fold	Present		3B	Expressed in many, but not all, cells of the neural tube, including the premigratory neural crest cells.
TS15: paraxial mesenchyme	Present		3B

Structure	Level	Pattern	Image	Note
TS18: outflow tract	Strong	Regionally restricted	3C	Expressed in vascular smooth muscle cells.
TS18: outflow tract endocardial cushion	Weak	Widespread	3C	Expressed throughout the mesenchyme, most likely in cells derived from both endocardial cells (by an epithelial-to-mesenchymal transformation) and neural crest cells.
TS18: outflow tract cardiac muscle	Present		3C	Reduced expression.
