Cov kws tshawb fawb ntawm Tel Aviv University muaj 3D luam lub plawv nyob siv tus neeg mob lub hlwb. Raws li lawv, cov cuab yeej no tuaj yeem siv ntxiv los tshem tawm qhov tsis xws luag hauv lub plawv mob thiab, tejzaum nws, ua kev hloov pauv.
Sau los ntawm cov kws tshawb fawb Israeli hauv li peb teev, lub siab me me dhau rau tib neeg - txog 2,5 centimeters lossis qhov loj ntawm luav lub siab. Tab sis thawj zaug, lawv muaj peev xwm tsim tau tag nrho cov hlab ntsha, ventricles thiab chambers siv tus cwj mem ua los ntawm cov neeg mob cov ntaub so ntswg.
"Nws yog biocompatible kiag li thiab haum rau tus neeg mob, uas txo qhov kev pheej hmoo ntawm kev tsis lees paub," hais tias tus thawj coj project xibfwb Tal Dvir.
Cov kws tshawb fawb tau cais tus neeg mob cov ntaub so ntswg rog rau hauv cov cellular thiab noncellular Cheebtsam. Cov hlwb tom qab ntawd tau "reprogrammed" rau hauv cov qia hlwb, uas tau hloov mus rau hauv cov leeg hlwb. Nyob rau hauv lem, cov khoom noncellular tau hloov mus rau hauv ib tug gel, uas ua hauj lwm raws li bioink rau 3D luam ntawv. Cov hlwb tseem xav tau kom loj hlob rau lwm lub hlis lossis yog li ua ntej lawv tuaj yeem tuav thiab cog lus, Dvir tau hais.
Raws li tsab ntawv tshaj tawm los ntawm lub tsev kawm ntawv, cov kws tshawb fawb yav dhau los tsuas tuaj yeem luam cov ntaub so ntswg yooj yim, tsis muaj cov hlab ntsha lawv xav tau ua haujlwm.
Raws li Dvir tau hais, yav tom ntej, lub siab lub ntsws luam tawm ntawm lub tshuab luam ntawv 3D tuaj yeem hloov mus rau tsiaj, tab sis tseem tsis tau hais txog kev sim rau tib neeg.
Tus kws tshawb fawb tau hais tias kev luam ntawv lub neej loj ntawm tib neeg lub siab tuaj yeem siv sijhawm ib hnub thiab ntau lab lub hlwb, thaum ntau lab lub hlwb tau siv los luam lub plawv mini.
Txawm hais tias nws tseem tsis tau paub meej tias nws puas yuav muaj peev xwm luam tawm lub siab zoo tshaj plaws rau tib neeg, tus kws tshawb fawb ntseeg tias tej zaum los ntawm kev luam ntawv ib feem ntawm lub siab, nws yuav muaj peev xwm hloov qhov chaw puas nrog lawv, rov ua haujlwm ntawm ib qho chaw. tib neeg lub cev tseem ceeb.
