Cov extracellular matrix , hu ua plasma, ua ntshav tshwj xeeb ntawm cov ntaub so ntswg sib txuas 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.

Ib yam li ntawd, cov ntshav puas muaj cov kab mob extracellular?

Cov Extracellular Matrix ntawm Ntshav Cov nkoj. Ntshav cov hlab ntsha yog cov txheej txheem zoo heev thiab cov qauv tsim, uas muaj ntau tshaj li cov raj yooj yim ua cov ntshav yuav luag txhua cov ntaub so ntswg ntawm lub cev. Cov extracellular matrix (ECM) ib ntshav nkoj pab txhawb rau ntau yam kev ua haujlwm ntawm lub ntshav nkoj.

Tsis tas li ntawd, lub extracellular matrix ua haujlwm li cas? Extracellular matrix (ECM) yog ib lub network molecule uas nws kim heev uas muaj peb yam tseem ceeb: protein, glycosaminoglycan, thiab glycoconjugate. ECM Cheebtsam, nrog rau cov cell adhesion receptors, cuam tshuam nrog kev sib koom ua ke sib koom ua ke uas cov hlwb nyob hauv txhua cov ntaub so ntswg thiab kabmob.

Tsuas yog li ntawd, dab tsi yog qhov extracellular matrix?

Anatomical cov ntsiab lus ntawm microanatomy. Hauv biology, lub extracellular matrix (ECM) yog peb-dimensional network ntawm extracellular macromolecules, xws li collagen, enzymes, thiab glycoproteins, uas muab cov qauv thiab biochemical txhawb rau cov hlwb nyob ib puag ncig.

Dab tsi yog peb yam ntawm extracellular matrix?

Lub extracellular matrix muaj peb yam tseem ceeb:

  • Cov viscous proteoglycans (heparan sulfate, keratan sulfate, chondroitin sulfate), uas cushion hlwb.
  • Insoluble collagen fibers, uas muab lub zog thiab resilience.
