Vim nws qhov sib txawv thiab muaj pes tsawg leeg, ECM ua tau ua haujlwm ntau yam, xws li muab kev txhawb nqa, cais cov ntaub so ntswg los ntawm ib leeg, thiab tswj kev sib txuas lus intercellular. Cov extracellular matrix tswj ib tug cell tus cwj pwm dynamic.
Tsis tas li ntawd, qhov kev ua haujlwm ntawm extracellular matrix yog dab tsi?
Cov extracellular matrix pab cov hlwb los khi ua ke thiab tswj ntau lub cellular muaj nuj nqi , xws li adhesion, migration, proliferation, thiab sib txawv. Nws yog tsim los ntawm macromolecules, hauv zos secreted los ntawm cov neeg nyob hauv hlwb.
Qhov thib ob, puas yog extracellular matrix hauv cell? Txawm tias tsiaj hlwb tsis nyob ib puag ncig cell phab ntsa, ntau ntawm cov cell hauv cov ntaub so ntswg ntawm multicellular kab mob yog embedded hauv ib extracellular matrix muaj cov proteins uas zais cia thiab polysaccharides. Cov extracellular matrix puv qhov chaw nruab nrab hlwb thiab khi hlwb thiab cov ntaub so ntswg ua ke.
Xav txog qhov no, dab tsi yog qhov extracellular matrix zoo li?
Hauv lwm lo lus, lub extracellular matrix feem ntau txiav txim siab li cas cov ntaub so ntswg zoo li thiab ua haujlwm. Cov extracellular matrix yog ua los ntawm proteoglycans, dej, minerals, thiab fibrous proteins. Ib tug proteoglycan yog tsim los ntawm ib tug protein core surrounded los ntawm ntev chains ntawm starch- nyiam molecules hu ua glycosaminoglycans.
Yuav ua li cas yog lub extracellular matrix puas lawm?
Tsis zoo hauv extracellular matrix Cov txheej txheem proteins hauv osteochondrodysplasias. Cov teebmeem thib ob rau extracellular matrix cov qauv protein tuaj yeem tshwm sim los ntawm qhov tsis xws luag Nyob rau hauv post-translational maturation, suav nrog hydroxylation, sulfation thiab proteolytic cleavage, thiab tsim cov osteochondrodysplasias txawv.

Cov kua dej extracellular hu ua dab tsi?
Extracellular fluid (ECF) qhia txog tag nrho cov kua hauv lub cev sab nraum lub hlwb ntawm txhua yam kab mob hauv lub cev. Extracellular kua yog nyob rau hauv ib puag ncig ntawm tag nrho cov multicellular tsiaj, thiab nyob rau hauv cov tsiaj nrog ib tug ntshav circulatory system, ib feem ntawm cov kua no yog ntshav plasma
Dab tsi yog qhov extracellular matrix ntawm cov ntshav?
Lub extracellular matrix, hu ua plasma, ua rau cov ntshav tshwj xeeb ntawm cov ntaub so ntswg vim nws yog kua. Cov kua dej no, uas feem ntau yog dej, perpetual suspends tsim cov ntsiab lus thiab ua rau lawv mus thoob plaws hauv lub cev nyob rau hauv lub plawv system
Yuav ua li cas koj tig lub matrix mus rau hauv tus kheej matrix?
VIDEO Ntxiv mus, yuav ua li cas koj pom qhov rov qab ntawm lub matrix siv tus lej matrix? Nws ua haujlwm tib yam rau matrices . Yog koj multiply a matrix (xws li A) thiab nws thim rov qab (hauv qhov no, A – 1 ), koj tau txais tus kheej matrix I.
Dab tsi yog extracellular signal molecules?
Extracellular signaling molecules yog cues, xws li kev loj hlob yam, cov tshuaj hormones, cytokines, extracellular matrix Cheebtsam thiab neurotransmitters, tsim los xa cov ntaub ntawv tshwj xeeb rau cov hlwb
Dab tsi yog cov ions nyob rau hauv siab tshaj plaws concentration nyob rau hauv lub extracellular kua?
Cov tshuaj no nyob rau hauv cov kua dej extracellular thiab intracellular. Nyob rau hauv cov kua dej extracellular, cov cation loj yog sodium thiab cov anion loj yog chloride. Qhov loj cation nyob rau hauv cov kua dej intracellular yog poov tshuaj. Cov electrolytes no ua lub luag haujlwm tseem ceeb hauv kev tswj hwm homeostasis
