| Abstract: | The coelom and blood vessel of 24 and 48 h amphioxus larva are examined using light and electron microscopes. The coelominc lining cells of amphioxus larva possess cilia and well developed Golgi bodies. A kind of secretory cells is also found in its coelom, which contains a prominant endoplasmic reticulum and many secretory vesicles. The blood vessels of amphioxus are first recognized as spaces arising in the extracellular matrix at proper positions. However, no cell component is found in the dosal aorta and subintestinal vein of the 48 h larva. |
