METHODS: According to adherent + Thy1.1 antibody and complement-purification method, cranium was opened to expose olfactory bulb. Thereafter, two olfactory bulbs were obtained to remove cerebral pia mater, blood capillary, and peripheral tissues; additionally, olfactory nerve layer and olfactory bulb granular layer were sheared into 1-mm3 pieces for extract single-cell suspension. The cells were adjusted at the density of 1×107 /L and incubated with poly-l-lysine-coated culture bottle or culture plate in 5% CO2 incubator at 37 ℃. On the third day, cells were cultured with serum-free DMEM/F12 culture media.

The superficial blood vessels could cross two or more pulmonary lobules, and the pleural superficial blood vessels and the interlobular blood vessels were mutual transitional. The outlines of lobules composed of vascular networks were various in size and form, and the lobular septa were also different in depth. The subpleural arterioles could be divided into arteriole, terminal arteriole, precapillary arteriole and capillary in turn according to the branching sequence of themselves. The plate-like, sieve-like and web-like vascular networks occurred in the subpleural microvascular networks.

After amputation, the expression of desmin appears first in the distal end epidermis and the peritoneum 4 d PA. The expression in the peritoneum lasts to the 14 d PA when expression of desmin appears in the musculature, while that in the distal end epidermis only lasts to the 8 d PA when the connective tissue below begins to express desmin. Moreover, from the 4 d PA, musculature and epidermis of the tube foot begin to express desmin and the expressions last to the 20 d PA. From 8-14 d PA, musculature of the ambulacral plate expresses myogenin and the peritoneum also expresses myogenin from 14-20 d PA. All these results indicate that precursor cells for muscle regeneration in adult starfish A.rollestoni are mainly from the distal end epidermis and the parietal peritoneum.
