Cell motility yog yuav tsum tau rau ntau yam tseem ceeb physiological txheej txheem thaum lub sij hawm kev loj hlob ntawm tes, xws li cell migration thaum gastrulation, axon kev taw qhia, cov ntaub so ntswg regeneration thiab embryological kev loj hlob. Unregulated cell migration tuaj yeem ua rau muaj mob qog noj ntshav, xws li thaum lub sijhawm metastasis.
Qhov tseem ceeb ntawm kev txav ntawm tes yog dab tsi?
Cell motility pab kom koj cov hlwb mus rau qhov chaw uas lawv yuav tsum yog. Qhov ntawd yog qhov tseem ceeb tshwj xeeb hauv kev tsim cov ntaub so ntswg. Feem ntau, cov progenitor, "stem-zoo li" hlwb tsis pom nrog rau cov hlwb uas paub tab. Cov hlwb no loj hlob mus rau hauv cov ntaub so ntswg paub tab, ces tsiv mus nyob rau qhov twg lawv yuav tsum mus.
cellular motility yog dab tsi?
Cellular motility yog kev txav txav ntawm lub xovtooj ntawm ib qho chaw mus rau lwm qhov los ntawm kev siv lub zog. Lub sij hawm suav nrog ntau hom kev txav, suav nrog kev ua luam dej, nkag, gliding thiab swarming.
Yuav ua li cas rau kev txav ntawm tes?
Txhua lub xovtooj ntawm tes yog qhov tshwm sim ntawm kev ua haujlwm kho tshuab; lawv xav tau roj (ATP) thiab cov proteins uas hloov lub zog khaws cia hauv ATP rau hauv kev txav. Lub cytoskeleton, cytoplasmic system ntawm fibers, yog qhov tseem ceeb rau kev txav ntawm tes. … Ib lub tshuab muaj ib chav tshwj xeeb ntawm cov enzymes hu ua motor proteins.
kev hloov pauv txhais li cas txog cov qauv ntawm cov hlwb?
motility txhais li cas txog cov qauv ntawm tes? lawv yuav ua luam dej deb ntawm kab ntawm inoculation nyob rau hauv thiaj li yuav nrhiav cov as-ham, ua rau muaj kev nruj kev nruj lossis cov huab lossis huab hauv nruab nrab. Yog hais tias cov kab mob no tsis yog motile, lawv tsuas yog loj hlob raws kab ntawm inoculation.
