Lub hematopoietic qia cell (HSC) qhov chaw yog qhov chaw ntawm lub cev uas HSCs nyob thiab rov tsim kho tus kheej. HSCs sab nraum qhov chaw tsis txhob rov ua tus kheej thiab pib txheej txheem sib txawv kom thaum kawg tsim kom muaj kev paub tab cov qe ntshav.

Tsuas yog li ntawd, lub stem cell niche tswj qia cell txawv li cas?

Lawv muab cov teeb liab uas khaws cov qia hlwb los ntawm sib txawv mus txog thaum lawv raug hu mus ua haujlwm.

Tom qab, lo lus nug yog, dab tsi yog pob txha pob txha niche? Niches yog cov ntaub so ntswg hauv zos microenvironments uas tswj thiab tswj cov qia hlwb. Cov qhov chaw yog perivascular, tsim ib feem los ntawm mesenchymal stromal hlwb thiab endothelial hlwb thiab feem ntau, tab sis tsis tas li, nyob ze trabecular. pob txha.

Ib tus kuj tseem yuav nug tau, dab tsi yog hematopoietic qia cell?

Ib tug tsis paub qab hau ntawm tes uas tuaj yeem loj hlob mus rau txhua hom ntshav hlwb , suav nrog cov ntshav dawb hlwb , ntshav liab hlwb , thiab platelets. Hematopoietic qia hlwb muaj nyob rau hauv cov ntshav peripheral thiab cov pob txha pob txha. Kuj tseem hu ua ntshav qia cell.

Puas yog osteoblast yog stem cell?

Cheebtsam uas yog qhov tseem ceeb rau osteoblast pob txha tsim muaj xws li mesenchymal qia hlwb ( osteoblast precursor) thiab cov hlab ntsha uas muab cov pa oxygen thiab cov as-ham rau kev tsim cov pob txha.
