B thiab T lymphocytes pib qhov twg?
Ob leeg B thiab T lymphocytes pib hauv pob txha pob txhatab sis tsuas yog B lymphocytes paub tab; T lymphocytes tsiv mus rau lub thymus kom dhau mus rau lawv cov maturation. Yog li B lymphocytes thiaj li hu ua vim lawv yog cov pob txha pob txha muab los, thiab T lymphocytes vim lawv yog thymus derived.
B thiab T cell tsim li cas?
Ob lub B thiab T hlwb yog cov lymphocytes uas yog muab los ntawm cov kab mob tshwj xeeb, hu ua multipotent hematopoietic qia hlwb, hauv cov pob txha. Tom qab lawv tau tsim nyob rau hauv cov pob txha pob txha, lawv yuav tsum paub tab thiab ua kom qhib tau. Txhua hom ntawm tes ua raws txoj hauv kev sib txawv mus rau lawv cov ntawv kawg, paub tab.
B thiab T lymphocytes pib qhov twg?
Cov kab mob hauv lub hauv paus pib, qhov twg B & T hlwb pib thiab paub tab yog pob txha thiab thymus.
