Abstract

AIm: This study aimed to analyze the effect of rat bone marrow-mesenchymal stem cells (rBM-MSCs) delivery on lesion site after spinal cord injury, and to observe the functional recovery after transplantation. MaterIal and Methods: MSCs were isolated from rat femurs and tibias. The experimental rat population was divided into four groups: only laminectomy (1); laminectomy+trauma (2); laminectomy+trauma+PBS (3); laminectomy+trauma+MSCs (4). Their motility were scored regularly. After 4-weeks, rats were sacrificed, and their spinal cords were examined for GFP labeled rBM-MSCs by immunostainings. Results: In the early posttraumatic period, the ultrastructures of spinal cord tissue were preserved in Group 4. The majority of cells forming the ependymal region around the central canal were found to be MSCs. The gray-and-white-matter around the ependymal region were composed of Nestin+/GFAP+ cells, with astrocytic-like appearance. The scores showed significant motor recovery in Group 4, especially in hind limb functions. However, no obvious change was observed in other groups. ConclusIon: The increase Nestin+/GFAP+ cells in the gray-and-white-matter around the ependymal region could indicate the potential to self-renew and plasticity. Thus, transplantation of rBM-MSCs might be an effective strategy to improve functional recovery following spinal cord trauma. In conclusion, molecular factors in cell fate decisions could be manipulated to enhance reparative potential of cell-based therapy.

Özet

AMAÇ: Bu çalışmada omurilik hasarı sonrası sıçan kemik iliği-mezenkimal kök hücrelerinin (sKİ-MKH) lezyon yerindeki etkisini analiz etmek ve transplantasyon sonrası işlevsel iyileşmeyi gözlemlemek amaçlandı. YÖNTEM ve GEREÇLER: MKH’ler sıçan femur ve tibialarından izole edildi. Deney sıçanları dört gruba ayrıldı: sadece laminektomi (1), laminektomi+ travma (2); laminektomi + travma + PBS (3); laminektomi + travma + MKH’ler (4). Sıçanların hareketleri düzenli olarak skorlandı. Dört hafta sonra sıçanlar sakrifiye edildi, omurilikleri immün boyamayla GFP işaretli sKİ-MKH’lerle incelendi. BULGULAR: Erken posttravmatik dönemde, Grup 4’teki omurilik dokusu ultrastrüktürel olarak korundu. Santral kanalın etrafındaki ependimal bölgeyi oluşturan hücrelerinin çoğu MKH’ler olarak saptandı. Ependimal bölgenin etrafındaki gri ve ak maddeler astrositik görünümlü Nestin+/ GFAP+ hücrelerden oluşmuştu. Grup 4’te özellikle arka bacak fonksiyonlarında motor iyileşme belirgindi. Buna karşın, diğer gruplarda belirgin değişiklik izlenmedi. SONUÇ: Ependimal bölgenin etrafındaki gri ve ak maddede Nestin+/GFAP+ hücrelerin artışı kendini yenileme ve plastisite potansiyellerini gösterebilir ve sKİ-MKH’lerin transplantasyonu spinal kord travması sonrası fonksiyonel iyileşmede etkili bir strateji olabilir. Sonuç olarak, moleküler faktörler hücre kaderini belirleyen hücre tabanlı tedavinin onarıcı potansiyelini artırmak için uygulanabilir.
