Lofalitsidwa pa webusayiti ya Rice University (Houston, Texas) , yomwe imafotokoza za chitukuko chaukadaulo chomwe chimachotsa chopinga chachikulu pakupanga mafakitale a ziwalo zopanga za anthu. Cholepheretsa choterechi chimatengedwa kuti ndi kupanga mapangidwe a mitsempha mu minofu yamoyo, yomwe imapereka maselo ndi zakudya, mpweya ndipo imakhala ngati woyendetsa mpweya, magazi ndi zamitsempha. Mitsempha yamagazi iyenera kukhala yanthambi bwino ndikukhalabe yolimba ponyamula zinthu mopanikizika.
Kuti asindikize minofu ndi dongosolo la mitsempha, asayansi adagwiritsa ntchito chosindikizira cha 3D chosinthidwa. Chosindikizira chimasindikiza ndi hydrogel yapadera mugawo limodzi pa pass. Pambuyo pa gawo lililonse, chitsanzocho chimakonzedwa ndi kuwala kwa buluu. Kusintha kwa chosindikizira chodziwika bwino kumayambira 10 mpaka 50 microns. Pofuna kuyesa lusoli, asayansi anasindikiza chitsanzo cha mapapo ndi maselo amene amatsanzira maselo a chiwindi. Mayesero adawonetsa kuti mapapo ochita kupanga amatha kupirira kusintha kwamphamvu ndikupatsanso oxygen bwino m'maselo a magazi omwe amapopedwa kudzera mumitsempha yopangira.
Ndizosangalatsa kwambiri ndi chiwindi. Kachiwindi kakang'ono ka maselo ochita kupanga adayikidwa m'chiwindi cha mbewa yamoyo kwa masiku 14. Pakuyesa, ma cell adawonetsa kuthekera. Sanafe, ngakhale kuti chakudya chinaperekedwa kwa iwo kupyolera mβzotengera zochita kupanga. Osuta ndi kumwa tsopano ali ndi chiyembekezo cha mwayi wachiwiri. Mozama, kukhazikitsidwa kwaukadaulo woperekedwa kudzapulumutsa miyoyo ndikubwezeretsa thanzi kumagulu ambiri a odwala. Izi zili choncho pamene zipangizo zamakono zili zofunika, osati kungolonjeza zabwino ndi chitonthozo.
