Puas muaj hlwb hauv cov hlab ntsha?
Endothelial cells tsim ib txheej cell uas kab tag nrho cov hlab ntsha thiab tswj kev sib pauv ntawm cov hlab ntsha thiab cov ntaub so ntswg ib puag ncig. Cov cim qhia los ntawm cov kab mob endothelial txhim kho kev loj hlob thiab kev loj hlob ntawm cov ntaub so ntswg sib txuas uas tsim cov txheej txheem nyob ib puag ncig ntawm phab ntsa ntawm cov hlab ntsha.
