Abstract:
Objective To investigate the characters of culture of neural stem cells(NSCs) from neonatal rats in different states in vitro.Methods Forty-two neonatal rats at age 7 days were divided randomly into 3 groups as control group,hypoxic group and hypoxic-ischemic group,each having 14 rats.Forteen rats of every group divided randomly into 7 small groups,each including 3 h,6 h,1 d,3 d,(7 d),14 d and 21 d,according to the time to put to death,each having 2 rats.After builting rat models of hypoxic-ischemic encephalopathy,NSCs from hippocampus in 3 groups were isolated,then cultured,passed,differentiated and differentiated with single cell clone and immunocytochemistry tecnique.Results NSCs in hippocampus from 3 groups were cultured in form of typical neuraospheres in suspension.The cells could be cloned,passed continuously and induced.There were differences among 3 groups when primary NSCs were cultured at 3 h and 6 h time points.But at 1 d,3 d,7 d,14 d and 21 d time points,clony neuraospheres from primary NSCs in hypoxic group were the most among 3 groups while clony neuraospheres from primary NSCs in hypoxic-ischemic group were the lest.Conclusions NSCs from hippocampus of neonatal rats in different states remain to be cultured,meanwhile,NSCs are decreased with increase of age,elongation of illness course and progress of state of an illness.
