Regeneration of spines and pedicellariae in echinoderms: A review

Abstract: Morphogenesis of tissues during regeneration of echinoderm spines and pedicellariae is reviewed. Regeneration of the skeleton is rather well documented while that of associated soft tissues is poorly investigated. In particular, little information is available on the early regeneration stages which follow wound healing. From the available information, it is suggested that regeneration of broken spines proceeds through a morphallactic process of which the organizational information, as well as the involved cell… Show more

“…This, coupled with the fact that sea urchins are capable of repairing and regenerating spines that have been damaged or completely severed [169,170], suggests that the spines themselves are designed to fracture when stressed, potentially remaining within a predator to deter further attack. Fig.…”

“…Echinoderm larvae can even produce a functional larval clone derived by budding from the original larval body (Bosch et al, 1989;Eaves and Palmer, 2003). Embryos from this phylum are well known for marked regulative development; many cells maintain 'multipotency' and change fates in response to changes in neighbouring cells (Horstadius, 1950(Horstadius, ,1973Ransick and Davidson, 1993;Dubois and Ameye, 2001), including the germ line (Goss, 1969;Emson and Wilkie, 1980;Eaves and Palmer, 2003;Vaughn and Strathmann, 2008;Ransick and Davidson, 1993).…”

“…Lateral branches are formed at regular intervals to connect neighboring micro-spines into a thin tri-dimensional fenestrated meshwork (the so-called open stereom). This thin meshwork subsequently thickens by secondary deposition of mineral on previously formed meshes (Heatfield, 1971;Mischor, 1975;Dubois and Ameye, 2001). …”
