Abaphandi kwiYunivesithi yaseTel Aviv baye baprinta intliziyo ephilayo nge-3D ngokusebenzisa iiseli zesigulana. Ngokutsho kwabo, obu buchwepheshe bunokusetyenziswa ngakumbi ukuphelisa iziphene kwintliziyo egulayo kwaye, mhlawumbi, ukwenza ukutshintshwa.
Ishicilelwe ngoososayensi bakwaSirayeli malunga neeyure ezintathu, intliziyo incinci kakhulu kumntu - malunga ne-2,5 centimeters okanye ubukhulu bentliziyo yomvundla. Kodwa okwesihlandlo sokuqala, bakwazi ukwenza yonke imithambo yegazi, ii-ventricles kunye namagumbi besebenzisa i-inki eyenziwe kwizicubu zesigulana.
"I-biocompatible ngokupheleleyo kwaye ifanelekile kwisigulane, esinciphisa umngcipheko wokulahlwa," watsho inkokeli yeprojekthi uProfesa Tal Dvir.
Abaphandi bahlula izicubu ezinamafutha zesigulana zibe ngamacandelo eselula kunye ne-noncellular. Emva koko iiseli "zaphinda zahlelwa kwakhona" kwiiseli ze-stem, eziguqulelwe kwiiseli zemisipha yentliziyo. Ngokulandelayo, imathiriyeli engeyiyo iselula yajikwa yaba yijeli, eyayisebenza njengebhayoink yoshicilelo lwe-3D. Iiseli zisafuna ukukhula enye inyanga okanye ngaphezulu ngaphambi kokuba zibethe kwaye zisebenze, utshilo u-Dvir.
Ngokutsho koshicilelo oluvela eyunivesithi, ngaphambili izazinzulu zazikwazi ukuprinta izicubu ezilula kuphela, ngaphandle kwemithambo yegazi ekufuneka isebenze.
Njengoko u-Dvir watshoyo, kwixesha elizayo, iintliziyo eziprintwe kwiprinta ye-3D zinokutshintshelwa kwizilwanyana, kodwa akukabikho ntetho yovavanyo ebantwini okwangoku.
Isazinzulu sathi ukushicilela intliziyo yomntu elingana nobomi kunokuthatha imini yonke kunye neebhiliyoni zeeseli, ngelixa izigidi zeeseli zisetyenziselwa ukuprinta intliziyo encinci.
Nangona kungekacaci ukuba kuya kukwazi ukuprinta iintliziyo eziphakamileyo kunezomntu, isazinzulu sikholelwa ukuba mhlawumbi ngokuprinta iindawo ezizimeleyo zentliziyo, kuya kuba nokwenzeka ukubuyisela iindawo ezonakalisiweyo kunye nabo, ukubuyisela ukusebenza kwentliziyo. ilungu elibalulekileyo lomntu.
