Cov no osteogenic hlwb tsis txawv nrog kev ua haujlwm siab mitotic; lawv tsuas yog pob txha xwb hlwb uas faib. Tsis paub qab hau osteogenic hlwb tau pom nyob rau hauv cov txheej sib sib zog nqus ntawm periosteum thiab cov leeg. Thaum lawv sib txawv, lawv loj hlob mus rau hauv osteoblasts.

Raws li, puas yog cov kab mob osteogenic cell qia hlwb?

Osteoclasts. Osteoprogenitor hlwb yog muab los ntawm primitive mesenchymal hlwb . Lawv tsim cov pejxeem ntawm qia hlwb uas tuaj yeem sib txawv rau qhov tshwj xeeb tshaj plaws-kev tsim cov pob txha hlwb (i.e. osteoblasts thiab osteocytes).

Kuj Paub, hom cell twg yog cov pob txha ua los ntawm? Cov nqaij pob txha yog ua los ntawm ntau hom pob txha hlwb. Osteoblasts thiab osteocytes tau koom nrog hauv kev tsim thiab ntxhia pob txha; osteoclasts koom nrog hauv resorption ntawm cov pob txha. Hloov kho (tiaj tus) osteoblasts ua cov kab mob hauv ob sab phlu uas tsim cov txheej txheem tiv thaiv ntawm cov pob txha.

Ntawm no, cov cell twg tsis yog los ntawm cov hlwb osteogenic?

Lawv pom nyob rau hauv cov pob txha nto, yog multinucleated, thiab pib los ntawm monocytes thiab macrophages, ob hom ntshav dawb hlwb , tsis los ntawm osteogenic hlwb . Osteoclasts tseem niaj hnub rhuav tshem cov pob txha qub thaum osteoblasts tseem niaj hnub tsim cov pob txha tshiab.

Dab tsi yog kev sib raug zoo ntawm osteogenic cells osteoblasts thiab osteocytes?

Osteogenic hlwb yog tsis sib txawv thiab tsim los rau hauv osteoblasts . Thaum twg osteoblasts tau daig hauv cov calcified matrix, lawv cov qauv thiab kev ua haujlwm hloov pauv; lawv ua osteocytes . Osteoclasts tsim los ntawm monocytes thiab macrophages thiab sib txawv ntawm cov pob txha hlwb.
