Lub peev xwm ntawm ib lub xovtooj sib faib thiab tsim tag nrho cov hlwb sib txawv hauv lub cev, suav nrog cov ntaub so ntswg extraembryonic. Hais lus nruj me ntsis, tsuas yog zygotes, thiab hauv qee cov kab mob lawv cov xeeb leej xeeb ntxwv tam sim ntawd, yog totipotent. … Primordial germ cells yog the founder cells for the germline.
Puas yog cov kab mob primordial pluripotent?
Embryonic qia (ES) hlwb yog muab los ntawm cov cell loj ntawm preimplantation embryos (1, 2), thiab embryonic kab mob (EG) hlwb yog muab los ntawm primordial germ cells (PGCs) (3, 4). Ob leeg ES thiab EG hlwb yog pluripotentthiab ua kom pom cov kab mob sib kis hauv kev sim ua cov chimeras (5, 6).
Puas yog cov kab mob primordial multipotent?
Primordial germ cells (PGCs) yog tus tsim hlwb ntawm txhua gametes. PGCs sib txawv los ntawm pluripotent epiblasts hlwb los ntawm mesodermal induction signals thaum gastrulation. … Kev hloov ntawm cov cell mus rau ESC kab lis kev cai tej yam kev mob tshwm sim nyob rau hauv reversion rau ib tug ESC-zoo li lub xeev.
Puas yog primordial germ cell yog stem cell?
Nyob rau hauv tib neeg, cov kab mob primordial cell (PGC) yog thawj hom kab mob uas tsis txawv txavuas yuav txawv ntawm gametes: spermatozoa lossis oocytes.
Puas yog cov kab mob primordial diploid?
Cov kab mob thawj zaug yog cov hauv paus chiv keeb ntawm cov spermatozoa thiab oocytes thiab yog li sawv cev rau cov poj koob yawm txwv ntawm cov kab mob. Zoo li tag nrho lwm cov hlwb somatic cov no yog diploid thiab hauvTib neeg embryos tuaj yeem pom nyob rau hauv thawj ectoderm (epiblast) nyob rau lub lim tiam thib ob.
