Hloov caj ces nyuj los tsim cov mis nyuj hypoallergenic

Cov kws tshawb fawb Lavxias tau tshaj tawm txoj kev vam meej ntawm cloning ib tug nyuj, uas nws cov noob caj noob ces tau hloov kho nyob rau hauv kev cia siab ntawm kev tsim cov mis nyuj tsis haum, raws li British "Daily Mail".

Tus nyuj cloned tam sim no muaj hnub nyoog 14 hli, hnyav li ib nrab ntawm ib tuj, thiab zoo li muaj lub voj voog me me.

Galina Singina, tus kws tshawb fawb ntawm Ernst Federal Science Center for Animal Husbandry tau hais tias "Txij li lub Tsib Hlis, tus nyuj tau ua haujlwm hauv thaj teb txhua hnub ntawm lub koom haum lwm tus nyuj," said Galina Singina, tus kws tshawb fawb ntawm Ernst Federal Science Center for Animal Husbandry, sau tseg tias "nws siv sijhawm los hloov kho, tab sis nws sai sai. tshwm sim."

ob txoj kev vam meej

Qhov kev vam meej ntawm qhov kev sim yog ob npaug, raws li tsab ntawv ceeb toom los ntawm Skoltech Lub Tsev Haujlwm Saib Xyuas Kev Tshawb Fawb thiab thev naus laus zis hauv Moscow, vim tias cov kws tshawb fawb tau ua tiav hauv cloning tus nyuj uas tuaj yeem hloov mus rau lwm pab tsiaj ntxiv rau kev hloov pauv cov noob hauv kev txiav txim. tsis tsim cov protein, uas ua rau lactose intolerance hauv tib neeg.

Singina thiab nws cov npoj yaig ntawm lub koom haum Skoltech thiab Moscow State University tau siv CRISPR/Cas9 thev naus laus zis los "kho tawm" cov noob lub luag haujlwm rau beta-lactoglobulin, cov protein uas ua rau "lactose malabsorption," hu ua lactose intolerance.

Nyuaj hloov cov noob ntawm nyuj

Cov kws tshawb fawb tau tuaj yeem clone tus nyuj siv SCNT, nrog rau lub nucleus ntawm ib txwm pub cell hloov mus rau hauv lub qe nrog nws cov nucleus tshem tawm. Tom qab ntawd cov embryo tau muab tso rau hauv lub tsev menyuam ntawm tus nyuj mus txog rau theem calving.

Thaum cov nas hloov caj ces yog qhov tshwm sim zoo sib xws, kev hloov pauv cov noob ntawm lwm hom yog qhov nyuaj dua, vim tias cov nqi siab thiab teeb meem, hais tias Peter Sergeev, tus xibfwb ntawm Skoltech Institute thiab tus kws sau ntawv ntawm kev tshawb fawb, cov txiaj ntsig ntawm uas tau luam tawm hauv Doklady Biochemistry thiab Biophysics.

qhov project zoo

"Yog li, cov txheej txheem uas ua rau yug tsiaj txhu nrog cov mis nyuj hypoallergenic yog ib txoj haujlwm zoo," Sergeev hais ntxiv.

Kwv yees li ntawm 70 feem pua ​​​​ntawm cov neeg hauv ntiaj teb raug kev txom nyem los ntawm qee hom lactose malabsorption, raws li National Institute of Diabetes thiab Digestive thiab raum Kab Mob, uas ua rau nws nyuaj rau lawv zom cov mis nyuj thiab lwm yam khoom noj siv mis.

Xib fwb Sergeev piav qhia tias cloning ib tug nyuj yog ib qho kev sim tiag tiag, thaum lub kauj ruam tom ntej yuav txhaj tshuaj tiv thaiv ib pab tsiaj ntawm kaum ob tus nyuj nrog hloov cov noob, txhawm rau tsim ib hom nyuj uas tsim cov mis nyuj hypoallergenic.
