CECs, los yog lub qhov muag endothelial hlwb , hmoov tsis, yog ploj lawm nrog hnub nyoog. Qhov kev txo qis ntuj no tsis tshua muaj teeb meem kho mob tshwj tsis yog qhov poob ntawm hlwb yog qhov txawv txav, xws li hauv Fuchs 'dystrophy, lossis muaj ntau dhau cell poob uas yuav tshwm sim nrog kev raug mob, feem ntau yog phais.
Ib yam li ib tus tuaj yeem nug, dab tsi yog qhov suav ntawm endothelial cell suav?
Muab tus lej lossis ntom ntawm endothelial hlwb yog tam sim no thaum yug, feem ntau yog txog 5,000, hlwb ib square millimeter. Muaj ib li qub , nce thiab qeeb poob ntawm endothelial hlwb nrog kev laus. Thaum muaj hnub nyoog 40 los yog li ntawd, tus suav xov tooj tau poob mus txog 3,000, hlwb /hli 2. Thaum muaj hnub nyoog 70 lossis 80 xyoo, qhov no yuav yog 2, 000 hlwb /hli 2.
Dab tsi yog endothelial cell tsis ua haujlwm? Endothelial tsis ua haujlwm yog ib yam mob uas endothelial txheej (hauv ob sab hauv) ntawm cov hlab ntsha me tsis ua txhua yam ntawm nws cov haujlwm tseem ceeb ib txwm. Vim li ntawd, ob peb yam tsis zoo tuaj yeem tshwm sim rau cov ntaub so ntswg uas muab los ntawm cov hlab ntsha.
Ntxiv mus, puas corneal cells regenerate?
Cov lub qhov muag endothelium yog da dej los ntawm kev lom zem, tsis yog los ntawm cov ntshav lossis qog ntshav, thiab muaj keeb kwm sib txawv heev, ua haujlwm, thiab pom los ntawm vascular endothelia.) Tsis zoo li lub qhov muag epithelium, cov hlwb ntawm endothelium ua tsis rov tsim dua.
Yuav muaj dab tsi tshwm sim thaum txheej txheej endothelial ntawm cov cell puas lawm?
Thaum twg Cov Endothelial Cells Txhaum Kev puas tsuaj mus rau endothelium txheej tuaj yeem ua rau cov kab mob vascular xws li ntshav siab, ntshav qab zib, kab mob plawv, thiab atherosclerosis, (kev tsim cov roj cholesterol hauv cov hlab ntsha uas tuaj yeem ua rau lub plawv nres lossis mob stroke).

Dab tsi yog txheej txheem uas cov cell yooj yim dhau los ua cov cell tshwj xeeb?
Cell sib txawv yog li cas generic embryonic hlwb ua cov hlwb tshwj xeeb. Qhov no tshwm sim los ntawm cov txheej txheem hu ua noob qhia. Kev qhia cov noob yog kev sib xyaw tshwj xeeb ntawm cov noob uas tau qhib lossis tawm (qhia lossis thawb), thiab qhov no yog qhov qhia tias lub xov tooj ntawm tes ua haujlwm li cas
Dab tsi yog cov txheej txheem uas tsim ntau cov cell los ntawm ib lub cell?
Lub cell tau txais ib hom kev faib cell hu ua mitosis. Hauv mitosis, ob lub hlwb hu ua tus ntxhais cell raug tsim, txhua qhov zoo ib yam rau niam txiv cell
Dab tsi yog txheej txheem uas lub cell faib ua ob lub cell ntxhais?
Mitosis yog txheej txheem tseem ceeb rau lub neej. Thaum lub sij hawm mitosis, lub xov tooj ntawm tes duplicates tag nrho nws cov ntsiab lus, suav nrog nws cov chromosomes, thiab sib cais los ua ob lub hlwb zoo tib yam. Vim tias cov txheej txheem no tseem ceeb heev, cov theem ntawm mitosis tau ua tib zoo tswj hwm los ntawm cov noob
ICD 10 tus lej yog dab tsi rau keeb kwm ntawm cell cell carcinoma?
Tus kheej keeb kwm ntawm lwm cov qog nqaij hlav malignant ntawm daim tawv nqaij Z85. 828 yog ib daim ntawv them nqi / tshwj xeeb ICD-10-CM code uas tuaj yeem siv los qhia txog kev kuaj mob rau kev them nyiaj rov qab. 2020 tsab ntawm ICD-10-CM Z85. 828 tau pib ua haujlwm thaum Lub Kaum Hli 1, 2019
Qhov txawv ntawm B cell thiab T cell lymphomas yog dab tsi?
Thaum B cov cell tsim cov tshuaj tiv thaiv kab mob uas tsom mus rau cov kab mob, T cells ncaj qha tua cov kab mob lossis cov kab mob uas muaj kab mob. Hom lymphoma no yog ib hom kab mob loj hlob sai uas kho tau zoo li mob leukemia
