Thaj chaw subgranular (SGZ) ntawm lub hippocampus muaj cov neeg laus neuronal progenitor hlwb uas koom nrog ntau theem kev loj hlob . Nws nyob nruab nrab ntawm granule cell txheej (GCL) thiab lub hilus ntawm lub dentate gyrus (DG)29.
Dab tsi yog qhov piav qhia yooj yim neurogenesis?
Neurogenesis yog txheej txheem los ntawm cov neurons tshiab tsim nyob rau hauv lub hlwb… Stem cells tuaj yeem faib ua ntu zus los tsim cov qia hlwb ntau dua, lossis sib txawv kom nce mus rau cov hlwb tshwj xeeb, xws li neural progenitor cells. Cov cell progenitor lawv tus kheej sib txawv rau hauv ib hom neurons.
subgranular zone yog dab tsi?
Thaj chaw subgranular yog txheej nqaim ntawm cov hlwb nyob nruab nrab ntawm granule cell txheej thiab hilus ntawm cov hniav gyrus. Cov txheej no yog tus cwj pwm los ntawm ntau hom hlwb, hom tseem ceeb tshaj plaws yog neural stem cells (NSCs) nyob rau ntau theem ntawm kev loj hlob.
thaj chaw subgranular nyob qhov twg?
Thaj chaw subgranular nyob hauv lub hippocampus, ntawm qhov sib cuam tshuam ntawm hilus thiab granular txheej ntawm hippocampus. Nws tau kwv yees tias kwv yees li 100 txog 150 neurons tau tsim nyob rau ib hnub hauv thaj tsam subgranular ntawm cov neeg laus nas.
Cov txheej txheem tshwj xeeb twg tshwm sim tshwj xeeb hauv Subventricular thiab Subgranular zones?
Neurogenesis tshwm sim hauv thaj chaw subventricular (SVZ) uas tsim cov kab hauv ob sab ntawm lub ventricles thiab thaj tsam subgranular uas tsim ib feem ntawm cov hniav gyrus ntawm thaj chaw hippocampus. Lub SVZ yog qhov chaw uas cov neuroblasts raug tsim, uas tsiv los ntawm cov rostral migratory kwj mus rau lub qhov muag olfactory.
