The regeneration of limbs in adult anurans.
It is generally accepted that among the amphibians only urodeles and larval anurans retain the power to regenerate limbs and digits. However, there have been reports of atypical limb regeneration in individual post-metamorphic frogs occurring spontaneously in nature and in the laboratory after simple amputation (reviewed by Vorontsova & Liosner, 1960). On occasion, atypical limb regeneration ha...
متن کاملComparative Assessment of the Whole-cell Pertussis Vaccine Potency Using Serological and Intracerebral Mouse Protection Methods
One of the most important QC tests of whole-cell pertussis vaccine (WCPV) is potency test. In this regard, mouse protection test (MPT) is the current potency method, which is associated with severe animal distress and large variability in results. The purpose of this study was to assess Pertussis Serological Potency Test (PSPT) as a serological alternative method to intracerebral challenge in M...
متن کاملThe regeneration of axolotl limbs covered by frog skin.
Forearm skin of Stage XXIV Rana pipiens, which cannot regenerate limbs, was removed and placed upon the skinned forearms of young axolotls. The axolotl limbs were amputated immediately through the level of the grafts. Frog epidermis migrated to cover the amputation surface. Dedifferentiation and early blastema formation occurred beneath the frog wound epidermis. Limb regeneration continued, but...
متن کاملMouse potency assay for Bordetella bronchiseptica bacterins.
A potency assay for Bordetella bronchiseptica bacterins has been developed using mice. The immunogenicities of three bacterins, B, C, and D, were evaluated for ability to prevent death in mice as compared with a reference standard bacterin (RSB-A). Bacterins RSB-A, B, and C were evaluated for ability to prevent death in mice as compared with a reference standard bacterin (RSB-A). Bacterins RSB-...
متن کاملRosiglitazone inhibits mouse liver regeneration.
The remarkable regenerative potential of the liver is well known. Recent investigations have shown that this regenerative response is impaired in mouse models of fatty liver disease. Other studies demonstrate that mice engineered for liver-specific overexpression of the peroxisome proliferator activated receptor gamma (PPARgamma) develop significant hepatic steatosis. These observations suggest...
