Abstract

Fibroblast growth factor (FGF) plays a role in the development of bone and cartilage. FGF-2is a member of this family and blocking of FGF-2 affects the bone development. In this study,effects of FGF-2 blocking on the formation of vertebrae in chick embryos before ossificationsand orientation of cervical vertebrae were investigated with histological examinations. In thisstudy, anti-FGF-2 was performed to chick embryos at E4th and E10th days. Samples weretaken in E15th days and changes in the cervical spine were evaluated as histochemically (withhematoxylin-eosin, Alizarin red, Masson's trichrome staining) and immunohistochemically(with iNOS, eNOS and TUNEL). Also changings were evaluated by morphometric analysis.In macroscopic examination of the cervical vertebrae significant difference was not detected.But in histochemical staining, defects were observed in cartilage and ossification process.Increasing in oxidative stress was demonstrated by iNOS and eNOS. Also apoptosis whichwas represented by tunnel was found to be increased. FGF-2 blocking affects the ossificationprocess in the cervical spine by inducing oxidative stress and apoptosis which results with celldeath.

Özet

Fibroblast büyüme faktörü (FGF) kemik, kıkırdak gelişiminde rol oynayan ve bu nedenlekemik oluşumunu yönlendiren bir etkendir. Bu ailenin bir üyesi olan FGF-2'nin bloklaması ilekemik gelişiminin etkilendiği gösterilmiştir. Bu çalışmada kemikleşme öncesi dönemde FGF- 2 bloklamasının tavuk embriyolarında vertebra oluşumuna etkisi ve servikal vertebraların buetki altında nasıl yönlendiği histolojik açıdan incelenmesi amaçlanmıştır. Çalışmamızda E4 veE10 günlerinde piliç embriyolarına anti FGF-2 uygulanarak E15 günü alınan örneklerdeservikal vertebralarda oluşan değişiklikler histokimyasal olarak hematoksilen-eosin, Alizarinkırmızısı, Mason trikrom boyaları ile immünohistokimyasal olarak iNOS, eNOS ve TUNELile ayrıca oluşan değişiklikler morfometrik analizler ile değerlendirildi. Servikal vertebralarınmakroskobik incelemelerinde önemli bir farklılık saptanmazken, histokimyasal boyamalardakıkırdaklaşma ve kemikleşme süreçlerinde bozukluklar, iNOS ve eNOS ile ortaya konanoksidatif stres artışı, ayrıca TUNEL ile gösterilen apoptoziste fazlalaşma olduğu bulundu.FGF ailesinin bir üyesi olarak FGF-2 bloklamasının servikal vertebralarda kemikleşmesürecini etkilediği ve bunun serbest oksijen radikallerinden kaynaklanan oksidatif stres veilişkili olabileceği apopitozu indükleyerek hücre ölümüne neden olduğunu göstermektedir.
