Lub podocytes muaj cov txheej txheem ntev taw hu ua pedicels, uas lub hlwb hu ua (podo- + -cyte). Pedicels qhwv ib ncig ntawm lub capillaries thiab tawm slits ntawm lawv. Cov ntshav yog lim los ntawm cov slits no, txhua lub npe hu ua ib qho kev lim dej los yog slit diaphragm lossis slit pore.
hom cell yog podocytes?
Podocytes, uas yog visceral epithelial cells, suav nrog cov teeb meem tseem ceeb hauv lub glomerulus. Cov hlwb no qhia cov vitamin D receptor [75] thiab ob qho tib si hauv vitro thiab hauv vivo kev tshawb fawb pom tau tias vitamin D tiv thaiv cov podocytes los ntawm kev raug mob.
cov hlwb podocytes nyob qhov twg?
Podocytes yog cov hlwb tshwj xeeb ntawm lub raum glomerulusuas qhwv ncig capillaries thiab cov hlwb nyob ze ntawm Bowman's capsule.
Bowmans capsule yog dab tsi?
Lub parietal epithelium ntawm Bowman lub tshuaj ntsiav yog txheej txheej thiab yog tsim los ntawm cov hlwb squamous epithelial yooj yim hu ua "parietal cells." Lub parietal txheej tsis ncaj qha cuam tshuam nrog kev pom los ntawm cov hlab ntsha.
Dab tsi yog qhov ua haujlwm ntawm cov hlwb podocyte?
Podocytes ua lub luag haujlwm tseem ceeb hauv glomerular muaj nuj nqi Ua ke nrog cov hlwb endothelial ntawm glomerular capillary voj thiab glomerular hauv qab daim nyias nyias lawv tsim cov teeb meem pom. Podocytes koom tes nrog cov hlwb mesangial los txhawb cov qauv thiab kev ua haujlwm ntawm glomerulus.
