Umbungu owenziweyo ongenaqanda okanye amadlozi.Ingaba iyayicombulula na ingxaki yobudlolo

Emva kweminyaka eyi-10 yophando, izazinzulu zenze i-embryo yegundane eyenziweyo eye yaqala ukuphuhlisa amalungu ngaphandle kweqanda okanye isidoda, ngokutsho kophando olutsha lwesayensi olupapashwe kwiphephancwadi leNdalo.

Ngokutsho kwe-CNN, konke okuthathiweyo ziiseli ze-stem, ezingabalulekanga kwaye zinokulawulwa, ukuba zibe ziiseli ezivuthiweyo ezinemisebenzi ekhethekileyo.

Umbungu owenziweyo ongenaqanda okanye amadlozi

Imodeli yethu ye-embryo yempuku ayiphuhlisi nje ingqondo kuphela, kodwa kunye nentliziyo ebethayo, watsho umbhali okhokelayo wophando uMagdalena Zrnica Goetz, unjingalwazi wophuhliso lwezilwanyana ezincancisayo kunye ne-stem cell biology kwiYunivesithi yaseCambridge eBritani.

Wongeze wathi: Akukholeleki, eli yayiliphupha nje, kwaye sisebenze kulo ishumi leminyaka, kwaye ekugqibeleni sikufezekisile oko besikunqwenela.

UZernica Goetz uqinisekisile ukuba abaphandi banethemba lokuhamba ukusuka kwimibungu yegundane ukuya ekudaleni iimodeli zokukhulelwa kwabantu okuqhelekileyo, isilumkiso sokuba abaninzi bayasilela kwizigaba zokuqala.

UGoetz wachaza ukuba ngokubukela iimbumba kwilebhu endaweni yokuba zisesibelekweni, izazinzulu ziye zayibona kakuhle le nkqubo, ukuze zifunde ukuba kutheni ukukhulelwa okuthile kungaphumeleli nendlela yokuzikhusela.

UMarianne Brunner, unjingalwazi webhayoloji kwiCalifornia Institute of Technology ePasadena, owayengabandakanyekanga kolu phando, wachaza ukuba eli phepha limele ukuqhubela phambili okuchulumancisayo kwaye lijongene nomngeni ojongene noososayensi ekufundeni iimbumba ezanyisayo esibelekweni.

UBenoit Bruno, umlawuli weGladstone Institute of Cardiovascular Diseases kunye nomphandi oyintloko eGladstone, uthe olu phando alusebenzi ebantwini kwaye kufuneka kubekho umgangatho ophezulu wokuphucula ukuba luncedo ngokwenene.

Kodwa abaphandi babona ukusetyenziswa okubalulekileyo kwixesha elizayo, njengoko uZernica Goetz waphendula kwaye wathi le nkqubo ingasetyenziselwa ngokukhawuleza ukuvavanya amachiza amatsha, yongeza ukuba kwixesha elide, njengoko izazinzulu zisuka kwiimbumba zemouse ezenziweyo ukuya kwimodeli ye-embryo yomntu, oku kunokuba negalelo. ukwakha amalungu angengowamvelo kubantu abafuna ukutshintshwa.
