Vatsvagiri vepaTel Aviv University vane 3D yakadhinda moyo mhenyu vachishandisa masero omurwere. Sekureva kwavo, tekinoroji iyi inogona kushandiswazve kubvisa kuremara mukati memoyo unorwara uye, pamwe, kuita transplantation.
Yakadhindwa nemasayendisiti eIsrael mumaawa angangoita matatu, moyo mudiki kumunhu - anenge 2,5 centimita kana saizi yemoyo wetsuro. Asi kekutanga, vakakwanisa kuumba tsinga dzose dzeropa, maventricles nemakamuri vachishandisa ingi yakagadzirwa nenyama yemurwere.
"Iyo yakazara biocompatible uye inokodzera murwere, izvo zvinoderedza njodzi yekurambwa," akadaro mutungamiri wepurojekiti Purofesa Tal Dvir.
Vatsvakurudzi vakaparadzanisa mafuta emurwere kuita masero uye noncellular components. Masero acho akabva "arongwazve" kuita stem masero, akashandurwa kuita maseru emoyo. Nekudaro, iyo noncellular material yakashandurwa kuita gel, iyo yakashanda se bioink ye 3D kudhinda. Masero achiri kuda kukura kweimwe mwedzi kana kupfuura asati arova uye chibvumirano, Dvir akadaro.
Maererano nekuburitswa kwenhau kubva kuyunivhesiti, kare masayendisiti aingokwanisa kudhinda zvinyoro zviri nyore, pasina tsinga dzeropa dzavanoda kuti dzishande.
Sezvakataurwa naDvir, mune ramangwana, mwoyo yakadhindwa pa 3D printer inogona kuiswa mumhuka, asi hapasati pave nekutaura kwekuedzwa kwevanhu.
Musayendisiti akati kudhinda mwoyo wemunhu wakaenzana nehupenyu kunogona kutora zuva rose uye mabhiriyoni emasero, nepo mamiriyoni emasero akashandiswa kudhinda mini heart.
Kunyange zvazvo zvisati zvanyatsojeka kana zvichave zvichiita kudhinda mwoyo inopfuura yevanhu, musayendisiti anotenda kuti zvichida nekudhinda zvikamu zvemoyo, zvichave zvichiita kutsiva nzvimbo dzakakuvadzwa nazvo, kudzorera kushanda kwe nhengo yakakosha yemunhu.
