Mesenchymal qia hlwb cog lus rau osteogenic kab thiab sib txawv rau hauv cov laus osteoblasts thiab osteocytes osteocytes Osteocytes yog cov hlwb nyob hauv cov pob txha nws tus kheej thiab yog 'entrapped' osteoblasts . Lawv yog cov post-proliferative, sawv cev rau cov neeg paub tab sib txawv tshaj plaws ntawm cov kab mob osteoblast. Muaj txog 25,000 osteocytes ib mm3 ntawm pob txha. https://www.ncbi.nlm.nih.gov › pmc › articles › PMC3341892
Ib qho ntsiab lus ntawm pob txha pob txha thiab lawv cov kev tswj hwm ntawm qhov sib txawv
los ntawm osteoprogenitor cells osteoprogenitor cells Taw Qhia. Osteoprogenitor hlwb, tseem hu ua osteogenic hlwb, yog qia hlwb nyob hauv cov pob txha uas ua lub luag haujlwm tsis zoo hauv kev kho pob txha thiab kev loj hlob. Cov hlwb no yog cov precursors rau cov pob txha tshwj xeeb tshaj plaws (osteocytes thiab osteoblasts) thiab nyob hauv cov pob txha pob txha. https://www.ncbi.nlm.nih.gov › books › NBK559160

thiab preosteoblasts teb rau ntau yam stimuli. Kev cog lus osteoblast, kev sib txawv, thiab kev ua haujlwm yog tswj hwm los ntawm ntau yam kev hloov pauv.
Dab tsi yog osteogenic hlwb?
Osteoprogenitor cells, tseem hu ua osteogenic hlwb, yog qia hlwb nyob hauv cov pob txha uas ua lub luag haujlwm tsis zoo hauv kev kho pob txha thiab kev loj hlob. Cov hlwb no yog cov precursors rau cov pob txha tshwj xeeb tshaj plaws(osteocytes thiab osteoblasts) thiab nyob hauv cov pob txha pob txha.
Dab tsi yog hom osteogenic hlwb?
pob txha muaj plaub hom cell sib txawv; osteoblasts, osteocytes, osteoclasts thiab pob txha hauv cov hlwb. Osteoblasts, pob txha hauv cov hlwb thiab osteoclasts muaj nyob rau ntawm pob txha pob txha thiab tau muab los ntawm cov hlwb mesenchymal hauv zos hu ua progenitor cells.
hom cell yog mesenchymal?
Mesenchymal qia hlwb yog multipotent neeg laus qia hlwb uas muaj nyob hauv ntau cov ntaub so ntswg, nrog rau txoj hlab ntaws, pob txha pob txha thiab cov nqaij rog. Mesenchymal qia hlwb tuaj yeem txuas ntxiv nws tus kheej los ntawm kev faib thiab tuaj yeem sib txawv rau ntau cov ntaub so ntswg nrog rau cov pob txha, pob txha mos, cov leeg nqaij thiab cov rog rog, thiab cov ntaub so ntswg sib txuas.
YPuas yog osteogenic cell yog qia cell?
Osteogenic qia hlwb yog muab los ntawm mesenchymal qia hlwb, thiab tuaj yeem sib txawv rau hauv osteoblasts thiab chondroblasts.

Cov hlwb mesenchymal txawv li cas?
Tib neeg pob txha pob txha-derived mesenchymal qia hlwb (MSCs) muaj peev xwm sib txawv rau hauv cov ntaub so ntswg xws li osteocytes, chondrocytes, thiab adipocytes hauv vivo thiab hauv vitro. Cov hlwb twg tsim los ntawm cov hlwb mesenchymal?
Yuav ua li cas rho tawm mesenchymal qia hlwb?
Mesenchymal Stem Cell Isolation los ntawm Umbilical Cord Tshuaj qaum (UCs) hauv cov tshuaj hypochlorite (1:3). Yuav UCs nrog PBS. Tau UCs hauv 10% FBS / DMEM-qabzib tsawg txog li 12 teev. Tshuaj UCs peb zaug nrog PBS. Txhaj cov leeg thiab cov hlab ntsha nrog 3mL 0.
Puas yog cov hlwb eukaryotic thawj lub hlwb?
Thawj lub eukaryotic hlwb - cov hlwb nrog lub nucleus ib sab hauv daim nyias nyias - khi organelles - tej zaum hloov zuj zus kwv yees li 2 billion xyoo dhau los . Qhov no tau piav qhia los ntawm txoj kev xav endosymbiotic endosymbiotic txoj kev xav Txoj kev xav tau hais tias mitochondria, plastids xws li chloroplasts, thiab tej zaum lwm cov organelles ntawm eukaryotic hlwb yog nqis los ntawm yav tas los dawb-nyob prokaryotes (ntau ze ze rau cov kab mob ntau dua li archaea) coj
Puas yog mesenchymal stromal cells qia hlwb?
Stromal cells - tseem hu ua mesenchymal stem cells (MSCs) - yog non-hematopoietic, ntau lub zog, lub hlwb rov ua dua tshiab uas muaj peev xwm ntawm trilineage sib txawv (mesoderm, ectoderm, thiab endoderm). Puas yog mesenchymal stem cells?
Puas yog cov paj hlwb genitofemoral yog cov paj hlwb peripheral?
Cov paj hlwb genitofemoral hais txog paj hlwb uas pom hauv plab. Nws cov ceg, ceg ntawm qhov chaw mos thiab cov ceg femoral muab kev nkag siab rau sab sauv sab xub ntiag, nrog rau daim tawv nqaij ntawm lub qhov quav sab hauv ntawm cov txiv neej thiab mons pubis hauv cov poj niam.
