Ishicilelwe kuwebhusayithi yeRice University (Houston, Texas) , ebika ukuthuthukiswa kobuchwepheshe okususa isithiyo esikhulu ekukhiqizweni kwezitho zokwenziwa zomuntu ezimbonini. Isithiyo esinjalo sibhekwa njengokukhiqizwa kwesakhiwo se-vascular ku-tissue ephilayo, ehlinzeka ngamangqamuzana anomsoco, umoya-mpilo futhi isebenza njengomqhubi womoya, igazi kanye ne-lymph. Isakhiwo se-vascular kumele sibe namagatsha kahle futhi sihlale siqinile lapho sithutha izinto ngaphansi kwengcindezi.
Ukuphrinta izicubu ngesistimu ye-vascular, ososayensi basebenzisa iphrinta ye-3D eguquliwe. Iphrinta iphrinta nge-hydrogel ekhethekile isendlalelo esisodwa ngokudlula. Ngemuva kwesendlalelo ngasinye, imodeli ilungiswa ngokuchayeka kokukhanya okuluhlaza okwesibhakabhaka. Ukulungiswa kwephrinta enolwazi kusuka kuma-microns ayi-10 kuye kwangama-50. Ukuze bahlole ubuchwepheshe, ososayensi banyathelisa imodeli yesikali yamaphaphu neqoqo lamangqamuzana alingisa amangqamuzana esibindi. Ukuhlola kwabonisa ukuthi amaphaphu okwenziwa angakwazi ukumelana noshintsho lwengcindezi futhi afake umoya-mpilo ngempumelelo kumangqamuzana egazi ayephonswa ngohlelo lwemithambo yokwenziwa.
Kuyathakazelisa nakakhulu ngesibindi. Ibhulokhi elincane lamaseli esibindi sokwenziwa lafakwa esibindini segundane eliphilayo izinsuku eziyi-14. Ngesikhathi sokuhlolwa, amaseli abonise ukusebenza. Abafanga, nakuba babenikezwa ukudla ngezitsha zokwenziwa. Ababhemayo nabaphuzayo sebenethemba lesibili. Ngokujulile, ukuqaliswa kobuchwepheshe owethulwe kuzosindisa izimpilo futhi kubuyisele impilo ezigabeni eziningi zeziguli. Kunjalo lapho ubuchwepheshe bubalulekile, hhayi nje ukuthembisa ukunethezeka nokunethezeka.
