Kampani ya biotechnology yochokera ku Chicago ya BIOLIFE4D yalengeza kupanga bwino kwa mtima wamunthu pogwiritsa ntchito 3D bioprinter. Mtima wawung'ono uli ndi mawonekedwe ofanana ndi chiwalo chamunthu chokwanira. Kampaniyo idati kupindulaku ndi gawo lofunikira kwambiri popanga mtima wochita kupanga woyenera kuwuika.
Mtima wochita kupanga unasindikizidwa pogwiritsa ntchito maselo a minofu ya mtima wa wodwalayo, otchedwa cardiomyocytes, ndi bioink yopangidwa kuchokera ku matrix a extracellular omwe amafanana ndi mtima wa mammalian.
BIOLIFE4D yoyamba yosindikiza minofu yamtima yamunthu mu June 2018. Kumayambiriro kwa chaka chino, kampaniyo inapanga zigawo za mtima za 3D, kuphatikizapo ma valve, ma ventricles ndi mitsempha ya magazi.
Izi zimaphatikizapo kukonzanso maselo oyera a m'magazi a wodwalayo (WBCs) kukhala maselo opangidwa ndi pluripotent stem cell (iPSCs kapena iPS), omwe amatha kusiyanitsa mitundu yosiyanasiyana ya maselo, kuphatikizapo cardiomyocytes.
Pamapeto pake, kampaniyo ikukonzekera kupanga mtima wamunthu wogwira ntchito bwino pogwiritsa ntchito 3D bioprinting. Mwachidziwitso, mitima yopangidwa motere ingachepetse kapena kuthetsa kufunikira kwa ziwalo zoperekera.
Inde, BIOLIFE4D si kampani yokhayo yomwe ikugwira ntchito paukadaulo wopanga ziwalo zopangira pogwiritsa ntchito kusindikiza kwa 3D.
Kumayambiriro kwa chaka chino, ofufuza ochokera ku yunivesite ya Tel Aviv pogwiritsa ntchito chosindikizira cha 3D, mtima wamoyo ndi kukula kwa mtima wa kalulu, ndipo akatswiri a sayansi ya sayansi ya zakuthambo ochokera ku Massachusetts Institute of Technology adatha kupanga makina ovuta a mitsempha pogwiritsa ntchito kusindikiza kwa 3D, zofanana ndi zomwe zimafunikira kuti zisunge kugwira ntchito kwa ziwalo zopangira.
