Co jsou antroboti?<\/h2>\n\n

Antroboti jsou mal\u00e9 skupiny lidsk\u00fdch bun\u011bk, kter\u00e9 se mohou pohybovat samy. Jsou vyrobeny z plicn\u00edch bun\u011bk dosp\u011bl\u00fdch lid\u00ed a jsou pokryty vlasovit\u00fdmi strukturami naz\u00fdvan\u00fdmi \u0159asinky. Tyto \u0159asinky umo\u017e\u0148uj\u00ed antrobot\u016fm pohybovat se v t\u011bsn\u00fdch smy\u010dk\u00e1ch, cestovat v p\u0159\u00edm\u00fdch lini\u00edch nebo se vrt\u011bt na m\u00edst\u011b.<\/p>\n\n

Jak byli antroboti vytvo\u0159eni<\/h2>\n\n

V\u011bdci na Tuftsov\u011b univerzit\u011b vyvinuli antroboty kultivac\u00ed plicn\u00edch bun\u011bk dosp\u011bl\u00fdch lid\u00ed po dobu dvou t\u00fddn\u016f. B\u011bhem t\u00e9to doby bu\u0148ky vyrostly do mnohobun\u011b\u010dn\u00fdch biorobot\u016f. V\u011bdci pot\u00e9 p\u011bstovali bu\u0148ky v roztoku, kter\u00fd zp\u016fsobil, \u017ee se \u0159asinky oto\u010dily sm\u011brem ven, co\u017e umo\u017enilo struktur\u00e1m pohybovat antroboty.<\/p>\n\n

Antroboti a hojen\u00ed ran<\/h2>\n\n

V laboratorn\u00edm experimentu bylo prok\u00e1z\u00e1no, \u017ee antroboti hoj\u00ed r\u00e1ny ve vrstv\u011b neuron\u016f. V\u011bdci po\u0161kr\u00e1bali vrstvu neuron\u016f v misce a pot\u00e9 p\u0159edstavili antroboty na m\u00edst\u011b \u0161kr\u00e1bnut\u00ed. B\u011bhem n\u011bkolika dn\u016f neurony znovu narostly a p\u0159eklenuly mezeru vytvo\u0159enou ranou.<\/p>\n\n

Mo\u017en\u00e9 aplikace antrobot\u016f<\/h2>\n\n

V\u011bdci v\u011b\u0159\u00ed, \u017ee antroboti by jednoho dne mohli b\u00fdt pou\u017eiti k l\u00e9\u010db\u011b nemoc\u00ed nebo pomoci s hojen\u00edm u lid\u00ed. Jsou zvl\u00e1\u0161t\u011b nad\u0161eni z potenci\u00e1lu antrobot\u016f v regenerativn\u00ed medic\u00edn\u011b.<\/p>\n\n

V\u00fdhody antrobot\u016f oproti xenobot\u016fm<\/h2>\n\n

Antroboti maj\u00ed oproti xenobot\u016fm, co\u017e jsou mal\u00ed roboti vyroben\u00ed z bun\u011bk \u017eab\u00edch embry\u00ed, n\u011bkolik v\u00fdhod. Na rozd\u00edl od xenobot\u016f nevy\u017eaduj\u00ed antroboti k tvarov\u00e1n\u00ed pinzetu ani skalpely. Mohou b\u00fdt tak\u00e9 vyrobeny z bun\u011bk dosp\u011bl\u00fdch, dokonce i bun\u011bk od star\u0161\u00edch pacient\u016f. Nav\u00edc lze antroboty vyr\u00e1b\u011bt v roj\u00edch, co\u017e je dobr\u00fd za\u010d\u00e1tek pro v\u00fdvoj terapeutick\u00e9ho n\u00e1stroje.<\/p>\n\n

Jak antroboti funguj\u00ed<\/h2>\n\n

V\u011bdci si st\u00e1le nejsou jisti, jak antroboti dok\u00e1\u017e\u00ed hojit r\u00e1ny. Domn\u00edvaj\u00ed se v\u0161ak, \u017ee antroboti mohou uvol\u0148ovat l\u00e1tky, kter\u00e9 podporuj\u00ed hojen\u00ed. Jin\u00e9 l\u00e1tky, jako je \u0161krob a k\u0159em\u00edk, nep\u0159inesly v jin\u00fdch experimentech stejn\u00e9 v\u00fdsledky.<\/p>\n\n

Budouc\u00ed v\u00fdzkum<\/h2>\n\n

V\u011bdci pokra\u010duj\u00ed ve studiu antrobot\u016f, aby se dozv\u011bd\u011bli v\u00edce o jejich potenci\u00e1ln\u00edch aplikac\u00edch. Pracuj\u00ed tak\u00e9 na v\u00fdvoji zp\u016fsob\u016f, jak \u0159\u00eddit pohyb a funkci antrobot\u016f.<\/p>\n\n

Z\u00e1v\u011br<\/h2>\n\n

Antroboti jsou slibn\u00e1 nov\u00e1 technologie s potenci\u00e1lem zm\u011bnit oblast regenerativn\u00ed medic\u00edny. Je zapot\u0159eb\u00ed dal\u0161\u00edho v\u00fdzkumu, abychom se dozv\u011bd\u011bli v\u00edce o jejich potenci\u00e1ln\u00edch aplikac\u00edch a vyvinuli zp\u016fsoby, jak \u0159\u00eddit jejich pohyb a funkci.<\/p>","protected":false},"excerpt":{"rendered":"
