Kambani yeChicago-based biotechnology BIOLIFE4D yakazivisa kubudirira kusikwa kweyakaderedzwa-pasi replica yemoyo wemunhu uchishandisa 3D bioprinter. Mwoyo mudiki une chimiro chakafanana senhengo yemunhu yakazara. Kambani iyi yakadana budiriro iyi chiitiko chakakosha pakugadzira moyo wekugadzira wakakodzera kuisirwa.
Mwoyo wekugadzira wakadhindwa pachishandiswa masero etsandanyama yemoyo yemurwere, anonzi cardiomyocytes, uye bioink yakagadzirwa kubva kune extracellular matrix inodzokorora zvimiro zvemoyo wemammalian.
BIOLIFE4D yekutanga bioprinted yemwoyo yemunhu tishu muna Chikumi 2018. Pakutanga gore rino, kambani yakagadzira yega 3D moyo zvikamu, kusanganisira mavharuvhu, ventricles uye tsinga dzeropa.
Kuita uku kunosanganisira kurongazve masero machena eropa omurwere (WBCs) kuita induced pluripotent stem masero (iPSCs kana iPS), ayo anogona kusiyanisa mumhando dzakasiyana dzemasero, kusanganisira cardiomyocytes.
Pakupedzisira, kambani inoronga kugadzira moyo wemunhu unoshanda zvizere uchishandisa 3D bioprinting. Mukufungidzira, mwoyo yekugadzira yakagadzirwa nenzira iyi inogona kuderedza kana kubvisa kudiwa kwemitezo yevanopa.
Ehe, BIOLIFE4D haisi iyo yega kambani iri kushanda pahunyanzvi hwekugadzira nhengo dzekugadzira uchishandisa 3D kudhinda.
Pakutanga gore rino, vaongorori veTel Aviv University uchishandisa 3D printer, moyo mhenyu hukuru hwemwoyo wetsuro, uye biotechnologists kubva kuMassachusetts Institute of Technology vakakwanisa kugadzira tsinga dzakaoma dzevascular vachishandisa 3D kudhinda, yakafanana neinodiwa kuchengetedza kushanda kwenhengo dzekugadzira.
