Myeloid hlwb muaj xws li monocytes, macrophages, neutrophils, basophils, eosinophils, erythrocytes, thiab megakaryocytes rau platelets. Cov ntaub so ntswg hematopoietic muaj hlwb nrog lub peev xwm tsim kho lub sij hawm ntev thiab luv luv thiab cog lus ntau zog , oligopotent, thiab cov tsis muaj peev xwm progenitors.

Zoo sib xws, dab tsi ua myeloid qia hlwb sib txawv rau?

Pluripotent hematopoietic qia hlwb li no sib txawv rau hauv luj cev as myeloid los yog lymphoid qia hlwb . Myeloid qia hlwb muab nce mus rau qib thib ob ntawm kab mob tshwj xeeb CFU hlwb uas mus tsim neutrophils, monocytes, eosinophils, basophils, mast hlwb , megakaryocytes, thiab erythrocytes.

Kuj Paub, puas muaj qia hlwb muaj keeb? Zoo li tag nrho hlwb hauv tib neeg lub cev, qia hlwb txhua tus faib ob peb yam qauv. Cov no suav nrog: A cev , uas muaj tag nrho cov xov tooj ntawm tes cov ntaub ntawv keeb kwm khaws cia ua DNA.

Kuj paub, puas yog hematopoietic qia hlwb ntau ntxiv?

Hematopoietic qia hlwb (HSCs) yog multipotent , tus kheej rov ua dua tshiab progenitor hlwb uas tsim los ntawm mesodermal hemangioblast hlwb . Tag nrho cov ntshav sib txawv hlwb los ntawm cov kab mob lymphoid thiab myeloid tshwm sim los ntawm HSCs. HSCs tuaj yeem pom nyob rau hauv cov neeg laus pob txha pob txha, cov ntshav peripheral, thiab cov hlab ntsha hauv plab.

Myeloid progenitor cells ua dab tsi?

Xovtooj hauv macrophage lineage yog tau los ntawm kev tsis paub qab hau myeloid progenitor hlwb hauv cov pob txha. Raws li qhov xwm txheej ib txwm muaj, myeloid progenitors Sib txawv rau cov laus monocyte-macrophages thiab granulocytes. Osteoclasts kuj tseem tuaj yeem ua tus antigen-nthuav tawm hlwb mus qhib T hlwb.
