Isibungu sokwenziwa esingenalo iqanda nesidoda..Ingabe siyayixazulula izinkinga zokungazali

Ngemva kweminyaka engu-10 yocwaningo, ososayensi baye benza umbungu wegundane wokwenziwa oseqale ukwakha izitho ngaphandle kweqanda noma isidoda, ngokusho kocwaningo olusha lwesayensi olushicilelwe kumagazini i-Nature.

Ngokusho kwe-CNN, konke okwadingeka ama-stem cells, angakhethekile futhi angashintshwa, abe amaseli avuthiwe anemisebenzi ekhethekile.

I-fetus yokwenziwa ngaphandle kweqanda noma isidoda

Imodeli yethu yombungu wegundane ayigcini nje ngokuthuthukisa ubuchopho, kodwa futhi inhliziyo eshayayo, kusho umbhali ohola ucwaningo uMagdalena Zrnica Goetz, uprofesa wokuthuthukiswa kwezilwane ezincelisayo kanye ne-stem cell biology eNyuvesi yaseCambridge eBrithani.

Wanezela: Akukholakali lokhu, leli bekuyiphupho nje, futhi sasebenza kukho ishumi leminyaka, futhi ekugcineni sikuzuzile ebesikufisa.

U-Zernica Goetz ukuqinisekisile ukuthi abacwaningi banethemba lokusuka emibungu yamagundane baye ekwakheni amamodeli okukhulelwa kwabantu okuvamile, exwayisa ngokuthi abaningi bayehluleka ekuqaleni.

UGoetz wachaza ukuthi ngokubuka imibungu endaweni yokucwaninga esikhundleni sesesibelethweni, ososayensi baba nombono ongcono ngale nqubo, ukuze bafunde ukuthi kungani abanye ukukhulelwa behluleka nokuthi bangakuvimbela kanjani.

UMarianne Brunner, uprofesa wesayensi yezinto eziphilayo eCalifornia Institute of Technology ePasadena, obengahileleki kulolu cwaningo, uthe leli phepha limele intuthuko ethokozisayo futhi libhekana nenselelo ososayensi ababhekana nayo lapho befunda imibungu yezilwane ezincelisayo esibelethweni.

UBenoit Bruno, umqondisi weGladstone Institute of Cardiovascular Diseases kanye nomphenyi omkhulu weGladstone, uthe lolu cwaningo alusebenzi kubantu futhi kumele kube nezinga eliphezulu lokuthuthuka ukuze kube usizo ngempela.

Kodwa abacwaningi babona ukusetshenziswa okubalulekile kwekusasa, njengoba uZernica Goetz ephendula futhi wathi le nqubo ingasetshenziswa ngokushesha ukuhlola izidakamizwa emisha, enezela ukuthi ngokuhamba kwesikhathi, njengoba ososayensi besuka emibungu yegundane yokufakelwa baye kumodeli wombungu womuntu, lokhu kungaba nomthelela. ukwakha izitho zokwenziwa zabantu abadinga ukufakelwa.
