Injuries from sea urchins result from penetration of the calcareous spines into the skin. Local pain of several days' duration is the most common symptom, but systemic reaction from toxins found in certain species can occur. There is no uniformly accepted successful treatment other than cleansing the wound.

The chromatin of sea urchin sperm
Biochimica et Biophysica Acta (BBA) - Gene Structure and Expression, 1987Digestion of sea urchin sperm nuclei with micrococcal nuclease yields nucleosomal monomer fragments of 151 and 164 base pairs. Prior trypsin treatment of the sperm chromatin does not alter the size of these monomer DNA fragments despite the fact that the H1 histone is reduced to a limit globular peptide of about 83 residues. Heterologous reconstitution

Cilia are exceptionally complicated subcellular structures involved in swimming and developmental signaling, including induction of left-right asymmetry in larval stages. We summarize the history of research on sea urchin embryonic cilia. The high salt method to isolate cilia is presented first; methods to block cilia formation and to lengthen cilia ...

The Complement System in Sea Urchins
2001Comparative immunology had its origin in the studies of inflammation by Elie Metchnikoff who proposed that the primary effectors of the immune response were circulating, amoeboid, phagocytic cells (Metchnikoff, 1891). In order to support this proposal, Metchnikoff reported that the bipinnaria larvae of a sea star would respond to physical injury (the ...
