Abstract (original English)

Mesenchymal stem cell (MSC) derived exosomes (MSC-DE) have been demonstrated to be potential candidates for the treatment of rat spinal cord injury (SCI). The effect of AD-MSC and AD-MSC-DE encapsulated into collagen and fibrin hydrogels on the treatment of SCI in a rat animal model was investigated for introducing a new effective SCI treatment method. The AD-MSC-DE was isolated using ultra-centrifugation at 100,000×g for 120 min and characterized by different methods. Fibrin and collagen hydrogels were synthesized and then mixed with AD-MSC-DE suspension. the characterized AD-MSC-DE were encapsulated into collagen and fibrin hydrogels. eighteen adult male Wister rats were randomly classified into 3 equal groups (n=6): the control group (SCI rat without treatment), SCI rat treated with either AD-MSC-DE encapsulated in collagen hydrogel or encapsulated in fibrin hydrogel groups. the treatment approaches were evaluated using clinical, histological, and molecular assays. The AD-MSC-DE encapsulated into fibrin and collagen groups showed better clinical function than the control group. The AD-MSC-DE encapsulated into fibrin and collagen also improved SCI-induced polio and leuko-myelomalacia and leads to higher expression of NF protein than the control group. In the AD-MSC-DE encapsulated into collagen and fibrin leads to up-regulation the mean levels of NEFL (23.82 and 24.33, respec
