Pues hay publicado en Nature un análisis completo de telómeros de Dolly... pero no puedo abrir el artículo desde casa.
Cuando pueda abrirlo desde el curro le echo un vistazo y te cuento si mencionan algo de los ovulos.

me da que me he liado. La función de la telomerasa y el acortamiento de los telómeros es progresivo y se correlaciona con la especialización de las diferentes subpoblaciones celulares. Así, en las células somáticas normales adultas especializadas, no se puede detectar la actividad telomerasa mientras que esta sigue presente en las celulas madre.

Sería de suponer que si cogiéramos una célula madre toti, pluri o puede que incluso multipotente y clonaramos una Dolly a partir de ahi, no tendría que haber problema alguno con el envejecimiento prematuro.

De todas formas, aunque el análisis de los telomeros de Dolly presentaron tal problema, al tratarse de un caso puntual si quisieramos ser cientificamente estrictos no podemos asociar a la clonación tal problema
