Kev Loj Hlob hauv Bioengineering: 3D Sau Pob Ntseg Tau Zoo Hloov Rau Thawj zaug

Raws li New York Times lub vev xaib, lub tuam txhab tshuaj kho dua tshiab hauv Tebchaws Meskas tau tshaj tawm ua ntej lub hlis no tias nws tau ua tiav kev cog qoob loo 3D-luam tawm pob ntseg los ntawm nws lub hlwb mus rau tus poj niam muaj hnub nyoog 20- xyoo uas tau yug los. pob ntseg deformed. Nov yog thawj qhov kev sim tshuaj siv 3D thev naus laus zis hauv kev kho mob. Qhov no yog ib qho kev xav tsis thoob hauv kev ua haujlwm ntawm cov nqaij mos engineering, raws li ntau tus kws tshaj lij ywj pheej.

Lub tuam txhab US 3D Biomedical tau hais tias cov duab ntawm pob ntseg tshiab luam tawm raws nraim tus poj niam lub pob ntseg sab laug. Lub pob ntseg tshiab, uas tau hloov pauv hauv lub Peb Hlis, regrows pob txha mos thiab muaj qhov zoo nkauj thiab zoo nkauj ntawm pob ntseg ntuj, lub tuam txhab tau hais.

"Nws tseem ceeb heev," said Adam Feinberg, tus xibfwb ntawm biomedical engineering thiab cov ntaub ntawv tshawb fawb thiab engineering ntawm Carnegie Mellon University. Dr. Feinberg nws tus kheej tsis koom nrog 3D Biomedical, nws yog lwm lub tuam txhab Co-founder ntawm Fluids, lub tuam txhab tshuaj regenerative uas kuj siv 3D tshuab luam ntawv. "Nws qhia tau hais tias nws tsis yog ib lo lus nug ntawm seb lub tshuab no puas ua tau, tab sis yog lo lus nug txog thaum twg," nws hais.

3D Biomedical tshaj tawm cov txiaj ntsig ntawm tus poj niam txoj kev phais kho dua tshiab hauv kev tshaj tawm xov xwm. Tab sis lub tuam txhab tsis tau tshaj tawm cov ntsiab lus ntawm kev phais, hais txog cov cai patent. Tsoomfwv tswj hwm yav dhau los tau ntsuas qhov kev sim tsim thiab teeb tsa cov qauv tsim khoom nruj, thiab cov ntaub ntawv yuav raug luam tawm hauv phau ntawv kho mob tom qab kev kawm tiav, lub tuam txhab tau hais.

11-Kev sim tshuaj rau tus neeg mob tseem tab tom ua tsis tu ncua, thiab muaj peev xwm ua rau tsis ua haujlwm lossis muaj teeb meem uas tsis tau xav txog. Tab sis ntau tus kws kho mob thiab cov thawj coj hauv tuam txhab hais tias kev tsis lees paub lub pob ntseg tshiab tsis zoo li muab cov hlwb siv tau los ntawm tus neeg mob cov ntaub so ntswg.

Qhov kev vam meej no yog xya xyoo hauv kev tsim. Tsis ntev los no, kev kawm tau ua ntau txoj hauv kev tshawb nrhiav kev hloov pauv hauv nruab nrog cev. Thaum Lub Ib Hlis Ntuj, cov kws phais neeg hauv Maryland tau hloov pauv hloov caj ces lub plawv npua rau hauv tus txiv neej muaj hnub nyoog 57- xyoo uas muaj lub plawv nres, txuas nws lub neej los ntawm ob lub hlis.

United Therapeutics muab cov npua transgenic rau saum toj no hais txog kev hloov lub plawv. Ib tus kws tshaj lij rau lub tuam txhab tau hais tias lawv tseem tab tom sim nrog 3D luam ntawv lub ntsws rau kev hloov pauv. Cov kws tshawb fawb ntawm Technion-Israel Institute of Technology tau tshaj tawm lub Cuaj Hli dhau los tias lawv tau luam tawm cov hlab ntsha uas tsim nyog los muab cov ntshav rau cov ntaub so ntswg cog.

Muab hais tias pob ntseg implanted siv ib tug me me clump ntawm cell kab derived los ntawm tus poj niam lub pob ntseg deformed, nws zoo nkaus li yog thawj paub piv txwv ntawm 3D luam ntawv cov ntaub so ntswg nyob.

Tseem, Dr Feinberg tau hais tias, pob ntseg sab nrauv yog ib qho yooj yim appendage uas tsis ua haujlwm ntau npaum li nws yog rau kev zoo nkauj. Nws ceeb toom tias txoj kev mus rau 3D luam ntawv cov khoom siv hauv nruab nrog cev - xws li lub siab, lub raum, lub siab thiab lub ntsws - tseem nyob deb heev: "Txawm tias los ntawm kev luam ntawv pob ntseg mus rau luam ntawv ib qho intervertebral disc yuav yog ib qho kev dhia loj. npau suav yuav ze rau qhov tseeb.
