Lub extracellular matrix (ECM) tsim muaj peb-dimensional network uas nyob ib ncig ntawm lub hlwb thiab ua raws li cov qauv thiab cov yam ntxwv rau cov ntaub so ntswg. … Hauv lub paj hlwb, ECM yog synthesized thiab secreted los ntawm ob leeg neurons thiab glia.
Puas tag nrho cov ntaub so ntswg muaj extracellular matrix?
Lub extracellular matrix (ECM) yog tsis yog cellular tivthaiv nyob rau hauv tag nrho cov ntaub so ntswg thiab kabmob, thiab muab tsis tau tsuas yog lub cev tseem ceeb scaffolding rau cov cellular constituents tab sis kuj pib tseem ceeb heev biochemical. thiab biomechanical cues uas yuav tsum tau rau cov ntaub so ntswg morphogenesis, sib txawv thiab homeostasis…
Cov ntaub so ntswg twg muaj cov kab mob ntxiv?
cov ntaub so ntswg sib txuasyog qhov ntau tshaj plaws thiab nthuav dav ntawm cov ntaub so ntswg. Cov ntaub so ntswg sib txuas muaj peb yam tseem ceeb: cov hlwb, fibers, thiab cov khoom hauv av. Ua ke cov khoom hauv av thiab cov fibers ua rau cov matrix extracellular.
Nyob rau hauv cov ntaub so ntswg extracellular matrix tsis tuaj?
Cov kab mob sib kis tsis zoo lossis tsis muaj nyob hauv cov ntaub so ntswg epithelial. Kev piav qhia: Lub intercellular matrix txhais tau hais tias qhov chaw nruab nrab ntawm ob lub hlwb uas tau them nrog collagen ntau.
Qhov twg ntawm 4 cov ntaub so ntswg uas muaj cov kab mob extracellular matrix?
Cov ntaub so ntswg muaj xws li cov ntaub so ntswg epithelial, cov ntaub so ntswg sib txuas, cov leeg nqaij thiab cov ntaub so ntswg. Cov molecules thiab fibers uas txuas cov tib neeg lub hlwb ua ke nyob rau hauv ib tug muab cov ntaub so ntswg yog hu ua extracellular matrix.
