Ipapashwe kwiwebhusayithi yeYunivesithi yaseRice (eHouston, eTexas) , ebika ukuphuhliswa kwetheknoloji esusa umqobo omkhulu kwimveliso yemveliso yezitho zokwenziwa komntu. Umqobo onjalo uthathwa njengemveliso yesakhiwo se-vascular kwi-tissue ephilayo, enika iiseli ezinomsoco, i-oksijeni kwaye isebenza njengomqhubi womoya, igazi kunye ne-lymph. Isakhiwo se-vascular kufuneka sibe ne-branched kakuhle kwaye sihlale sinobunzima xa sihambisa izinto phantsi koxinzelelo.
Ukushicilela izicubu nge-vascular system, izazinzulu zasebenzisa umshicileli we-3D olungisiweyo. Umshicileli uprinta nge-hydrogel ekhethekileyo kwinqanaba elinye lokudlula. Emva koluhlu ngalunye, imodeli igxininiswe ngokukhanya okuluhlaza okwesibhakabhaka. Isisombululo somshicileli onamava sisuka kwi-10 ukuya kwi-50 microns. Ukuvavanya ubuchwephesha, izazinzulu ziye zaprinta umlinganiselo wemiphunga kunye neeseli ezilinganisa iiseli zesibindi. Uvavanyo lubonise ukuba imiphunga eyenziweyo inokumelana nokutshintsha koxinzelelo kwaye ifake i-oksijini ngempumelelo kwiiseli zegazi eziye zaphonswa nge-artificial vascular system.
Inika umdla ngakumbi ngesibindi. Ibhloko encinci yeeseli zesibindi sokwenziwa zafakwa esibindini sempuku ephilayo kangangeentsuku ezili-14. Ngexesha lovavanyo, iiseli zibonise ukusebenza. Abazange bafe, nangona babebonelelwa ngokutya ngezitya zokwenziwa. Abatshayayo nabasela utywala ngoku banethemba lesibini ithuba. Ngokunyanisekileyo, ukuphunyezwa kobuchwephesha obubonisiweyo kuya kusindisa ubomi kunye nokubuyisela impilo kwiindidi ezininzi zezigulane. Le yimeko xa itekhnoloji ibalulekile, hayi nje ukuthembisa ngokulula kunye nokuthuthuzela.
