Clones Help Develop Ewe Feeding Strategy, Myra Yelland, Rob Kelly, John Davies, Johan Greeff

Journal of the Department of Agriculture, Western Australia, Series 4

Cloned sheep are not a new animal to the researchers of Agriculture WA, but the method that produced Dolly is.

Cloned sheep have been produced at the great Southern Research Institute as early as the mid 1980s. Myra Yelland, Rob Kelly, John Davies and Johan Greef outline how clones are used in experimental studies on wool production

Acceleration Of Amphibian Forelimb Regeneration By Polypeptide Growth Factors, Gehan H. Fahmy, Raymond E. Sicard

Journal of the Minnesota Academy of Science

Growth factors are potentially important modulators of epimorphic regeneration. This study examined effects of intraperitoneal administration of selected growth factors on limb regeneration of adult newts, Notophthalmus viridescens. These agents stimulated regeneration, producing overlapping but nonidentical effects. Fibroblast growth factor-2 (FGF-2) and insulin-like growth factor I (IGF-I) stimulated bud emergence (8.3 ± 0.6 and 8.3 ± 0.7 days, respectively, vs 11.4 ± 1.1 days for controls). Progression to the cone stage was enhanced by both FGF-2 and transforming growth factor beta 5 ( TGF-~ 5) ; 14.6 ± 0.5 and 15.4 ± 0.4 days with FGF-2 and TGF-~5 , respectively, …
