Abstract

Background and Aims: Angiogenesis is essential for both physiological and pathological processes. The aim of this study was to examine for angiogenic activity and micro-vessel density in the odontogenic keratocysts (OKC), dentigerous cysts (DC) and radicular cysts (RC), and to evaluate their biological significance. Materials and Methods: Twenty-five cases of OKCs, 10 DCs and 10 RCs were examined by immunohistochemistry for expression of two pro-angiogenic factors; vascular endothelial growth factor (VEGF) and VEGF receptor 1 (VEGFR1), and an anti-angiogenic factor; plasminogen, as well as three endothelial markers [CD34, CD105, and von Willebrand Factor (vWF)]. Protein expression rates were scored as 0 (no staining), 1 (50% stained cells) and mean micro-vessel density (MCD) was obtained. Results: Significantly higher VEGFR1 in the lining epithelium of OKCs compared to DCs and RCs suggests that epithelial- derived VEGFR1 plays a crucial role as an angiogenesis inducer (p

Özet

Amaç: Anjiogenezis fizyolojik ve patolojik süreç için temel bir gereksinimdir. Bu çalışmanın amacı, odontojenik keratokistler (OKCs), dentigeröz kistler (DCs)ve radiküler kistlerdeki (RCs) minidamar yoğunluğu ve anjiogenik aktiviteyi incelemek ve de bunların biyolojik önemini değerlendirmektir. Gereç ve Yöntem: 25 adet OKCs, , 10 adet DCs ve 10 adet RCs vakası 3 endotelial belirteç ; CD34, CD105 ve non Willebrand faktör (vWF) ‘in yanısıra iki pro-anjiogenetik faktör; vasküler endotelial büyüme faktörü (VEGF) ve VEGF reseptör 1(VEGFR1) ve de, bir anti-anjiogenik faktör olan plazminojenin salınımı yönünden immünohistokimyasal yolla incelendi.Protein salınım değerleri 0 (boyanma yok), 1 (< % 25 boyanmış hücre), 2 (%25 - %50 arası boyanmış hücre) olarak skorlandı ve ortalama mikro-damar yoğunluğu (MCD) elde edildi. Bulgular: DCs ve RCs ‘e kıyasla epitel duvarındaki yüksek VEGFR1 düzeyi VEGFR1’in anjiyogenezis indükleyici olarak önemli bir rol oynadığı izlenimi uyandırmaktadır. VEGF ve plazminojen salınım değerleri 3 kist tipi arasında önemli bir fark göstermemiştir ki buda bu sitokinlerin pro- ve anti- anjiyogenetik faktör olarak minör role sahip olduğunu göstermektedir. OKC ‘lerdeki ortalama CD34 ilişkili ve vWF MCD skorları, DCs ve RCs le kıyaslandığında yeni damar gelişimi ayırt edilemezken, önemli derecede düşüktü (p
