TS21: back skin	Present	Regionally restricted	2G' , 2G	Expressed in the Golgi body in the stained subcutaneous lymphatic sprouts. The Golgi body consistently aligned in the direction of migration in wild type sprouts.
TS21: dermis	Present	Regionally restricted	2G' , 2G	Expressed in the Golgi body in the stained subcutaneous lymphatic sprouts. The Golgi body consistently aligned in the direction of migration in wild type sprouts.
TS21: lymph sac	Present	Regionally restricted	2G' , 2G	Expressed in the Golgi body in the stained subcutaneous lymphatic sprouts. The Golgi body consistently aligned in the direction of migration in wild type sprouts.
