“V zadnji \u0161tudiji je prvi\u010d uspelo v laboratoriju razviti \u010dlove\u0161ko jaj\u010dece od zelo zgodnje faze razvoja do popolne zrelosti,” so sporo\u010dili z univerze v Edinburghu, kot poro\u010da francoska tiskovna agencija AFP.<\/p>\n

Jaj\u010deca so razvili iz zelo zgodnje faze razvoja celic iz tkiva jaj\u010dnika. Razvili pa so jih do te mere, da je mo\u017ena njihova oploditev. To je doslej uspelo zgolj pri jaj\u010decih mi\u0161i, medtem ko so \u010dlove\u0161ka razvili iz kasnej\u0161e faze razvoja.<\/p>\n

Ugotovitve \u0161tudije, objavljene v znanstveni reviji Molecular Human Reproduction, bi lahko pripomogle predvsem pri zdravljenju neplodnosti \u017eensk, ki imajo tovrstne te\u017eave zaradi zdravljenja, kot je kemoterapija. Jaj\u010dne celice v zgodnji fazi razvoja bi lahko dale zamrzniti pred zdravljenjem, nato bi celice v laboratoriju razvili, kasneje pa lahko tudi oplodili s semen\u010dicami.<\/p>\n

Rakave bolnice sicer lahko pred kemoterapijo odstranijo del jaj\u010dnika, vendar pa pri ponovni vstavitvi tkiva tvegajo ponoven razvoj raka.<\/p>\n

Strokovnjaki, ki niso sodelovali v raziskavi, so ocenili, da so rezultati obetavni, vendar pa so poudarili, da bi lahko trajalo \u0161e ve\u010d let, da bi to tehniko spremenili v varno in preizku\u0161eno terapijo zdravljenja.<\/p>\n

“Trajalo bo ve\u010d let, da bodo to spremenili v terapijo. Vendarle pa gre za pomemben preboj, ki bi lahko v prihodnosti dal upanje neplodnim \u017eenskam,” je povedal Channa Jayasena z univerze Imperial College London.<\/p>\n

Robin Lovell-Badge z in\u0161tituta Francisa Cricka pa je menil, da je postopek “zelo neu\u010dinkovit”, saj se zgolj tri \u010detrtine celic razvije v zrela jaj\u010deca, \u0161e navaja AFP.<\/p>\n","protected":false},"excerpt":{"rendered":"
