It was a major obstacle to axonal restoration. Safe therapeutic intervention by the use of bone marrow derived stem cells (BMMSCs) transplantation applied in the present study could reduce spinal disability. Material and methods: Forty male albino rats were divided into four groups: GI: negative control (n = 10 rats);GII: positive control after SCI (n = 10 rats);GIII: SCI + BM - MSCs intravenous injected and GIV: SCI + BM - MSCs intra lesion injected (n = 10 rats in each group). The samples were taken from spinal cord tissues around the region of injury and were subjected to histological, immunohistochemical assessment. RNA extraction and real time PCR for detection of nerve regeneration and astrocyte response to the injury were also performed. Results: Clinical improvement occurred by the enhancement in the Basso, Beattie and Bresnahan (BBB) score after SCI. Histological examinations showed positive regenerative responses in GIV compared to GIII. Conclusion: BM-MSCs transplantation has a promising role in enhancing the microenvironment for nerve regeneration through stumbling the glial scaring formation and inflammatory response after chronic spinal cord injury especially by using intra-lesion route injection. 展开更多

The neonatal hypoxic-ischemic encephalopathy(HIE)is an important cause of neurological morbidity and mortality in neonates.Cell therapy is considered a promising method for treating severe neurological disorders such as this one.Stem cells have the capacity for self-renewal and differentiation into certain cell lineages.The present study was aimed to find out the most beneficial route of bone marrow-derived mesenchymal stem cells(BMSCs)administration for the attenuation of experimentally induced HIE in neonatal rats.Sixty neonatal rats were divided randomly into four groups.Group 1:control group.Group 2:rats were exposed to bilateral ligation of cephalic arteries.Group 3:rats were exposed to bilateral ligation of cephalic arteries and then underwent intravenous(IV)BMSC injection.Group 4:rats were exposed to bilateral ligation of cephalic arteries and then underwent intracerebroventricular(ICV)BMSC injection.The animals were evaluated by(a)neurobehavioral tests;(b)histopathology,i.e.,histological and immuno-histochemical studies;and(3)gene expression studies.The BMSC treated groups(3 and 4)showed improvement in neurobehavioral tests,histopathological studies,and gene expression,as compared to non-injected lesioned rats(Group 2)with better improvement in Group 4(ICV injections)than in Group 3(IV injections). 展开更多
