THE ROLE OF SATELLITE CELLS IN CRUSH INJURY OF RAT SKELETON MUSCLE

Year 2013, Volume: 3 Issue: 1, 1 - 7, 03.10.2013

Abstract

The crush type of injury in rat skeletal muscle is often used in tissue degeneration and regeneration. After crush injury muscle tissue begins to regenerate. In this process, it is accepted that satellite cells play an important role which are very sensitive to muscle injury. The aim of this microscopic study was to examine role of satellite cells in muscle regeneration in crush injury. This research was done the department of  Histology&Embryology in Eskişehir Osmangazi University in 2008. Ethic approval of this study has been received. During the study, the whole essential and ethics conditions
have been done. In the study 36 Spraque-Dawley rats were used. The rats were separated into 5 groups as test and control groups. Crush type of injury has been applied on muscles of right hind extremities of testing group rats by applying 3.5 kg of weight for 6 hours. In according to testing periods rats were anaesthetized intraperitoneally with ketamine 30mg/kg + xylazine 10mg/kg and sacrificied 3, 7, 14 and 21-day intervals. After crush injury, increased satellite cells were particularly observed on day 7. Also
significant increased of satellite cells and regenerated myofibrils were detected on day 14. However, satellite cells were seen on day-21 were similar to control group. In crush injuries, number of satellite cells were markedly increased and actively involved into regeneration process of the skeleton muscle.

Abstract

İskelet kasında doku dejenerasyonu ve rejenerasyonunun incelenmesinde ezilme (crush) tipi
yaralanma oldukça sık kullanılmaktadır. Ezilme yaralanmasının ardından kas hemen rejenerasyona
başlar.Bu süreçte kas hasarına oldukça duyarlı olan satellit hücrelerinin önemli rol üstlendiği
düşünülmektedir.Bu çalışmada sıçanların iskelet kasında oluşturulan ezilme yaralanmasında satellit
hücrelerin kas rejenerasyonu sürecinde nasıl bir rol üstlendiği mikroskobik düzeyde araştırılmıştır. Bu
araştırmada toplam 36 adet Spraque-Dawley türü sıçan kullanıldı. Sıçanlar kontrol grubu ve 3 günlük,
7 günlük, 14 günlük ve 21 günlük deney grupları olacak şekilde 5 gruba ayrıldı. Deney grubundaki
sıçanların sağ arka ekstremitelerine 6 saat süreyle 3,5kg'lık ağırlık konularak kaslar üzerinde ezilme
tipi yaralanma oluşturuldu. Deney sürelerine göre sıçanlar ketamin (30mg/kg) + xylazine (10mg/kg)
anestezi ile uyutularak sakrifiye edildiler ve mikroskobik incelemeler için kas doku örnekleri alındı.
Crush yaralanmasından sonra özellikle 7.günde satellit hücrelerin yaralı bölgede sayıca artmış olduğu
görüldü. Aynı şekilde 14. günde satellit hücrelerin fazlalığı ve rejenere miyofibrillerin bulunması
dikkat çekti. 21. günde ise satellit hücreleri kontrol grubuna benzer şekilde gözlendi. Satellit
hücrelerinin ezilme yaralanmasında iskelet kasının rejenerasyonuna aktif bir şekilde katıldıkları
mikroskobik düzeyde gözlendi.
