Stereomicroscopic images of the lymph ducts and two lymph nodes. (A) Transparent lymph ducts beside the caudal vena cava before the Alcian blue (AB) injection. (B) The lymph ducts become blue immediately after the AB injection into the lymph nodes. (C) The lymph ducts become transparent again after being washed for 2 hours by lymph flow. The thin blue PVS has become visible in the lymph ducts. LN = lymph node; PVS = primo vessel system.
