In spite of its enormous scientific significance, this discovery failed to trigger much public concern, possibly because the donor cells were derived from pre-implantation stage embryos. The major breakthrough in terms of public recognition has happened when Ian Wilmut et al. To access this article, please choose from the options below. Developmental Biology 01/01/06 Non-equivalence of embryonic and somatic cell nuclei affecting spindle composition in clones. Open Archive Abstract Cloning by nuclear transfer remains inefficient but is more efficient when nuclei from embryonic cells or embryonic stem cells (ECNT) are employed as compared with somatic cells (SCNT).
The factors determining efficiency have not been elucidated. We find that somatic and embryonic nuclei differ in their ability to organize meiotic and mitotic spindles of normal molecular composition. Calmodulin, a component of meiotic and mitotic spindle chromosome complexes (SCCs), displays sharply reduced association with the SCC forming after SCNT but not ECNT. Abbreviations SCC, spindle chromosome complex; pmSCC, pseudo-meiotic spindle chromosome complex; SCNT, somatic cell nuclear transfer; ECNT, embryonic cell nuclear transfer Keywords Cloning nuclear transfer; Meiosis; Mitosis; Spindle; Calmodulin Introduction The ability to produce genetically identical offspring by nuclear transfer has existed for about five decades.

Massive public opposition US Food and Drug Administration (FDA) is about to approve cloned meat and milk for the market. A recent poll commissioned by the International Food Information Council (a non-profit organization supported by the food, beverage and agricultural industries) found nearly 60 percent of respondents would not touch products from cloned animals with only 9 percent “very likely” to buy them. Europe's dilemma Not surprisingly, the European Commission has decided to stay put. Daughter of cloned cow born in UK But events may have overtaken this decision. Le site CLONE SAFETY. ADIT 01/05/04 Le clonage animal au Japon (fiche de synthèse) OIE - Revue Scientifique et Technique, Volume 24 (1), Avril 2005 La biotechnologie. Résumé : Certaines applications parmi les plus prometteuses de la biotechnologie ont vu le jour dans les domaines de la santé et de la production animales ; c’est le cas de la reproduction assistée, des nanotechnologies appliquées au diagnostic et des systèmes d’administration de médicaments « intelligents », sans oublier les vaccins toujours plus performants et les techniques de diagnostic de plus en plus sophistiquées.
Il importe néanmoins de s’assurer que ces nouvelles technologies soient évaluées correctement et appliquées de façon responsable. Ce numéro de la Revue fait le point sur les politiques, les institutions et les cadres réglementaires opérationnels au niveau national, régional et international et examine le rôle des organismes chargés d’élaborer des normes en la matière, en particulier l’Organisation mondiale de la santé animale (OIE).
