Muaj nuj nqi ntawm basal lamina.

Cov basal lamina muab kev txhawb nqa rau epithelium hla, txwv kev sib cuag ntawm cov cell epithelial thiab lwm hom cell hauv cov ntaub so ntswg thiab ua raws li lub lim dej tso cai tsuas yog dej thiab cov lwg me me hla mus.

Xav txog qhov no, hom ntaub so ntswg twg yog basal lamina?

cov kab mob epithelial

Ib qho ntxiv, puas yog cov ntaub so ntswg txuas hauv qab lamina? Cov basal lamina ua ib daim nyias nyias sab nraud, uas nyob nruab nrab ntawm cov ntaub so ntswg sib txuas thiab sab hauv qab ntawm ib txheej cell. Cov txheej txheem cellular no tuaj yeem muaj cov kab mob endothelial lossis epithelial, thiab cov cell cell secretes txawv molecular Cheebtsam ntawm basal lamina.

Hauv qhov no, qhov txawv ntawm basal lamina thiab hauv qab daus membrane yog dab tsi?

Cov qhov sib txawv ntawm a basal lamina thiab a hauv qab daus membrane yog li A) basal lamina yog tuab. B) lawv pw ntawm qhov chaw sib txawv ntawm epithelium. Cov protein txuas hauv qhov chaw sab nrauv koom nrog cov plaques cytoplasmic ntawm cov cell epithelial uas nyob ib sab hauv hom kev sib txuas ntawm tes no.

Daim ntawv twg yog collagen IV hauv qab lamina noj?

Ob yam no ua rau cov collagen rau daim ntawv v paj,. daim ntawv ntawm basal lamina . Collagen IV yog qhov kev siv ntau dua, as opposed to the old terminology of "type- IV collagen ". Collagen IV muaj nyob hauv txhua qhov metazoan phyla.
