Beche rekugadzira risina zai kana urume..Inopedza dambudziko rekushaya mbereko here

Mushure memakore gumi ekutsvagisa, vesainzi vakagadzira embryo yembeva iyo yatanga kuumba nhengo dzisina zai kana urume, sekutsvagurudza kutsva kwesainzi kwakaburitswa mujenari Nature.

Sekureva kweCNN, zvese zvazvaitora aive stem maseru, ayo asina hunyanzvi uye anogona kushandiswa, kuti ave maseru akakura ane mabasa akakosha.

Artificial fetus isina zai kana urume

Wembeva yedu embryo modhi haingori uropi chete, asiwo moyo unorova, akadaro munyori anotungamira wekudzidza Magdalena Zrnica Goetz, purofesa wekukura kwemammalian uye stem cell biology paYunivhesiti yeCambridge kuBritain.

Akawedzera kuti: Izvi hazvitendeseki, uku kwaingova kurota, uye takashanda pazviri kwemakore gumi, uye takazowana zvataishuvira.

Zernica Goetz akasimbisa kuti vaongorori vanotarisira kutama kubva pambeva embryos kuenda kugadzira mhando dzepamuviri dzevanhu dzakajairwa, yambiro yekuti vazhinji vanokundikana mumatanho ekutanga.

Goetz akatsanangura kuti nekutarisa mazai ari murabhoritari panzvimbo pemudumbu, masayendisiti akawana maonero ari nani pamusoro pemaitirwo acho, kuitira kuti adzidze kuti sei dzimwe mimba dzichikundikana uye kuti dzinodzivirirwa sei.

Marianne Brunner, purofesa webiology paCalifornia Institute of Technology muPasadena, uyo asina kubatanidzwa muchidzidzo ichi, akati bepa iri rinomiririra kufambira mberi kunonakidza uye rinogadzirisa dambudziko rinosangana nesainzi pakudzidza mammalian embryo mudumbu.

Benoit Bruno, director weGladstone Institute of Cardiovascular Diseases uye mukuru wekuongorora weGladstone, akati tsvakiridzo iyi haishande kuvanhu uye panofanirwa kuve nedanho repamusoro rekuvandudza kuti rinyatsobatsira.

Asi vatsvakurudzi vanoona kushandiswa kwakakosha kweramangwana, sekupindura kwaZernica Goetz uye akati nzira iyi inogona kushandiswa pakarepo kuedza mishonga mitsva, achiwedzera kuti nekufamba kwenguva, sezvo masayendisiti anofamba kubva kune yakagadzirwa mbeva embryos kuenda kumuenzaniso we embryo yemunhu, izvi zvinogona kubatsira. kuvaka nhengo dzechigadzirwa dzevanhu vanoda kuisirwa.
