Basal Cell vs Squamous Cell
Basal thiab squamous hlwb yog ob hom hlwb pom nyob rau hauv cov ntaub so ntswg epithelial. Lub luag haujlwm tseem ceeb ntawm cov ntaub so ntswg epithelial yog muab kev tiv thaiv thiab kev txhawb nqa rau cov kabmob hauv lub cev. Nws npog yuav luag txhua qhov chaw ntawm lub cev lossis hauv ob sab phlu nrog rau ntawm daim tawv nqaij, lub cev hauv nruab nrog cev xws li lub qhov ntswg, qhov ncauj, pob ntseg thiab lwm cov kab noj hniav, tso zis, ua pa thiab ua pa, thiab tag nrho cov hlab ntsha. Tag nrho cov hlwb hauv cov ntaub so ntswg epithelial faib los ntawm mitosis.
Basal Cells
basal hlwb yog cubic los yog columnar zoo li cov hlwb uas tsim basal txheej hauv epidermis. Cov hlwb no kuj pom muaj nyob rau lwm qhov chaw, qhov twg cov ntaub so ntswg epithelial pom nyob rau hauv lub cev. Nws yog ib qho tseem ceeb kom nco ntsoov tias ntau lwm hom cell hauv cov ntaub so ntswg yog muab los ntawm cov basal hlwb. Tag nrho cov basal hlwb nyob rau hauv qab daus txheej, uas yog ib tug yam ntxwv feature ntawm cov ntaub so ntswg epithelium. Basal hlwb muaj basophilic cytoplasm thiab elliptical nucleus, uas muaj chromatin. Tsis tas li ntawd, basal hlwb muaj desmosomes, qhov sib txawv junctions, thiab hemidesmosomes, uas yog ib qho tseem ceeb rau cell-cell txuas, kev sib txuas lus ntawm tes thiab kev sib txuas nrog basal membrane thiab extracellular matrix feem.
Squamous Cells
Squamous cells yog cov hlwb tiaj tus uas pom nyob rau hauv cov ntaub so ntswg epithelial. Raws li kev npaj ntawm tes, muaj ob hom squamous epitheliums; yooj yim squamous thiab stratified squamous. Yooj yim squamous epithelium muaj ib txheej ntawm squamous hlwb. Cov ntaub so ntswg no tuaj yeem pom nyob rau hauv ob sab ntawm cov hlab ntsha thiab lub cev kab noj hniav, thiab qhov chaw ntawm lub raum tubules. Lub luag haujlwm tseem ceeb ntawm cov hlwb squamous yooj yim yog kev tiv thaiv thiab nqus. Stratified squamous epithelium muaj ntau lub cell txheej ntawm squamous hlwb nrog rau lwm hom ntawm epithelial hlwb xws li cuboidal thiab columnar hlwb. Stratified squamous cov ntaub so ntswg tuaj yeem pom hauv epidermis, hauv ob sab phlu ntawm lub qhov ncauj, txoj hlab pas, thiab qhov chaw mos. Lub luag haujlwm tseem ceeb ntawm cov ntaub so ntswg no yog kev tiv thaiv, zais cia, thiab nqus.
Qhov txawv ntawm Basal Cell thiab Squamous Cell yog dab tsi?
• Cov duab ntawm cov hlwb basal txawv ntawm cubic mus rau columnar thaum lub hlwb squamous yog tiaj tus.
• basal hlwb feem ntau tsim thawj ib txheej ntawm cov hlwb, uas nyob rau hauv qab daus daim nyias nyias, whereas squamous cell feem ntau pom nyob rau hauv lub basal hlwb.
• Lub luag haujlwm tseem ceeb ntawm cov hlwb basal yog tsim lwm cov hlwb hauv cov ntaub so ntswg epithelial, whereas lub luag haujlwm ntawm squamous hlwb yog secretion, tiv thaiv, thiab nqus.
