Khomo e fetotsoeng ka liphatsa tsa lefutso ho hlahisa lebese la hypoallergenic

Bafuputsi ba Russia ba phatlalalitse katleho ea ho kopanya khomo, eo liphatsa tsa lefutso tsa eona li fetotsoeng ka tšepo ea ho hlahisa lebese le khahlanong le allergic, ho ea ka "Daily Mail" ea Brithani.

“Ho tloha ka May, khomo e ’nile ea sebetsa lekhulong letsatsi le leng le le leng har’a likhomo tse ling tsa setsi,” ho boletse Galina Singina, mofuputsi oa Ernst Federal Science Center for Animal Husbandry, a hlokomela hore “ho ile ha nka nako ho ikamahanya le maemo, empa ho ile ha potlaka. e etsahetse.”

katleho habeli

Katleho ea teko e habeli, ho latela tlaleho e tsoang ho Skoltech Institute of Science and Technology e Moscow, hobane bafuputsi ba ile ba atleha ho etsa cloning khomo e ileng ea khona ho ikamahanya le mohlape o mong ntle le ho fetola liphatsa tsa lefutso ka tatellano. ho se hlahise protheine, e bakang ho se mamelle lactose ho batho.

Singina le basebetsi-'moho le eena Setsing sa Skoltech le Univesithi ea Naha ea Moscow ba sebelisitse theknoloji ea CRISPR/Cas9 ho "khothatsa" liphatsa tsa lefutso tse ikarabellang bakeng sa beta-lactoglobulin, protheine e bakang "lactose malabsorption," e bitsoang ho se mamelle ha lactose.

Bothata ba ho fetola liphatsa tsa lefutso tsa likhomo

Bafuputsi ba ile ba khona ho kopanya khomo ka ho sebelisa SCNT, ka nucleus ea sele e tloaelehileng ea mofani e fetisetsoang ka lehe le tlosoa nucleus. Ka mor'a moo, lesea le sa tsoa emoloa le ile la kenngoa ka pōpelong ea khomo ho fihlela nakong ea ho tsoala.
