Studies on regeneration of the lizard's tail.

چکیده
SvNorsis. The present paper is concerned mainly with studies from my laboratory on regeneration of the lizard's tail. Over the past five years my students and I have focused our attention on: (1) a careful description of the histology of tail regeneration; (2) the role of neural elements (nerve and ependyma) in the initiation of regeneration; (3) the role of the ependymal epithelium in the guidance of regenerating central fibeis: and (4) the development of techniques of tissue culture applicable to this system.

Effects of Tail Clipping on Larval Performance and Tail Regeneration Rates in the Near Eastern Fire Salamander, Salamandra infraimmaculata
Tail-tip clipping is a common technique for collecting tissue samples from amphibian larvae and adults. Surprisingly, studies of this invasive sampling procedure or of natural tail clipping--i.e., bites inflicted by predators including conspecifics--on the performance and fitness of aquatic larval stages of urodeles are scarce. We conducted two studies in which we assessed the effects of poster...
متن کاملEffect of vitamin A on acid and alkaline phosphatase activities during tail regeneration in the tadpoles of the Asian toad
Anuran amphibians have the potential to restore their lost tail by regeneration, although, unlike urodeles their regeneration capacity is restricted to larval stages. Application of vitamin A or retinoids to tail amputated tadpoles causes abnormal tail regeneration and subsequently leads to development of ectopic organs (limbs and pelvic girdles) at the site of the tail, a phenomenon widely kno...
متن کاملAutotomy, tail regeneration and jumping ability in Cape dwarf geckos (Lygodactylus capensis) (Gekkonidae)
Many studies have examined the effect of caudal autotomy on speed and behaviour of lizards escaping over horizontal surfaces, but there have been few studies on lizards escaping over vertical surfaces and, in particular, species that jump between surfaces. We examined jumping by the Cape dwarf gecko (Lygodactylus capensis) in terms of individuals’ varying states of tail autotomy and regeneratio...
متن کاملEarly requirement of Hyaluronan for tail regeneration in Xenopus tadpoles.
Tail regeneration in Xenopus tadpoles is a favorable model system to understand the molecular and cellular basis of tissue regeneration. Although turnover of the extracellular matrix (ECM) is a key event during tissue injury and repair, no functional studies to evaluate its role in appendage regeneration have been performed. Studying the role of Hyaluronan (HA), an ECM component, is particularl...
