Inkampani yase-Chicago ye-biotechnology, i-BIOLIFE4D, imemezele ukwakhiwa ngempumelelo kwe-replica eyehlisiwe yenhliziyo yomuntu kusetshenziswa i-3D bioprinter. Inhliziyo encane inesakhiwo esifanayo nesitho somuntu esiphelele. Inkampani ibize le mpumelelo njengengqophamlando ebalulekile ekudaleni inhliziyo yokwenziwa elungele ukufakelwa kabusha.
Inhliziyo yokwenziwa yanyatheliswa kusetshenziswa amangqamuzana emisipha yenhliziyo yesiguli, abizwa ngokuthi ama-cardiomyocytes, kanye ne-bioink eyenziwe nge-extracellular matrix ephinda izici zenhliziyo yesilwane esincelisayo.
I-BIOLIFE4D izicubu zenhliziyo yomuntu zokuqala ezenziwe nge-bioprinted ngoJuni 2018. Ngasekuqaleni kwalo nyaka, inkampani yakha izingxenye zenhliziyo ze-3D ngazinye, okuhlanganisa ama-valve, ama-ventricles nemithambo yegazi.
Le nqubo ihilela ukuhlela kabusha amangqamuzana egazi amhlophe esiguli (WBCs) abe ama-pluripotent stem cells (iPSCs noma i-iPS), angakwazi ukuhlukana abe izinhlobo zamaseli ahlukahlukene, okuhlanganisa ama-cardiomyocyte.
Ekugcineni, inkampani ihlela ukukhiqiza inhliziyo yomuntu esebenza ngokugcwele isebenzisa i-3D bioprinting. Ngokombono, izinhliziyo zokwenziwa ezenziwe ngale ndlela zinganciphisa noma ziqede isidingo sezitho ezinikelayo.
Yiqiniso, i-BIOLIFE4D akuyona ukuphela kwenkampani esebenza kubuchwepheshe bokudala izitho zokwenziwa usebenzisa ukuphrinta kwe-3D.
Ngasekuqaleni konyaka, abacwaningi base-Tel Aviv University usebenzisa iphrinta ye-3D, inhliziyo ephilayo ilingana nenhliziyo kanogwaja, futhi izazi ze-biotechnologists ezivela e-Massachusetts Institute of Technology zakwazi ukwenza amanethiwekhi ayinkimbinkimbi emithambo esebenzisa ukuphrinta kwe-3D, afana nalawo adingekayo ukuze kugcinwe ukusebenza kwezitho zokwenziwa.
