Rakadhindwa pawebhusaiti yeRice University (Houston, Texas) , iyo inoshuma kuvandudzwa kwehunyanzvi hunobvisa chipingamupinyi chikuru kukugadzirwa kwemaindasitiri kwenhengo dzemunhu dzakagadzirwa. Chipingamupinyi chakadaro chinoonekwa sekugadzirwa kwechimiro chevascular munyama inorarama, inopa masero ane chikafu, okisijeni uye inoshanda semugadziri wemhepo, ropa uye lymph. Iro vascular structure inofanira kunge yakanyatsogadziriswa uye inoramba iine simba pakutakura zvinhu pasi pekumanikidzwa.
Kudhinda matishu ane vascular system, masayendisiti akashandisa yakagadziridzwa 3D printer. Iyo printer inodhinda ine yakakosha hydrogel mune imwe layer pane imwe pass. Mushure mechikamu chimwe nechimwe, muenzaniso wacho unogadziriswa nechiedza chebhuruu. Kugadziriswa kweprinta ine ruzivo kubva pa10 kusvika ku50 microns. Kuti vaedze tekinoroji, masayendisiti akadhinda muenzaniso wemapapu uye seti yemasero anotevedzera masero echiropa. Miedzo yakaratidza kuti mapapu ekugadzira aikwanisa kumirisana nekuchinja kwekumanikidza uye nekubudirira oxygenate masero eropa akapombwa kuburikidza neyakagadzirwa vascular system.
Zvinotonyanya kunakidza nechiropa. Kabhuroko kadiki kemasero echiropa ekugadzira akaiswa muchiropa chembeva mhenyu kwemazuva gumi nemana. Panguva yekuedza, masero akaratidza kushanda. Havana kufa, kunyange zvazvo zvokudya zvaipiwa kwavari nemidziyo yakagadzirwa. Vanoputa uye vanonwa zvino vane tariro yemukana wechipiri. Zvakakomba, kuitwa kweiyo tekinoroji yakaratidzwa kuchaponesa hupenyu uye kudzoreredza hutano kumapoka mazhinji evarwere. Iyi ndiyo nyaya kana tekinoroji yakakosha, uye kwete kungovimbisa nyore uye kunyaradza.
