Abstract

Amaç: Hücrelerin LPS (Lipopolisakkarit)’ye enflamatuvaryanıtları in-vitro deneylerde sıklıkla kullanılmaktadır. Buna rağmen hücre kültürü çalışmaları için LPS ’nin doğru dozunun belirlenmesinde zorluklarla karşılaşılmaktadır. Maksimum yanıt veren LPS konsantrasyonunun belirlenmesi in vitro enflamatuvar deneyler için kritik bir noktadır. Bu çalışmanın amacı LPS’nin 293T insan renal hücre dizisindeki konsantrasyon bağımlı etkisinin yeniden değerlendirilmesidir.

Yöntem: Bu çalışmada LPS ile stimule edilmiş 293T hücre hattı Xcelligence Real-Time Cell Analyzer (RTCA) sisteminde incelendi. LPS ’nin artmış konsantrasyonlarının 293T hücre hattı üzerindeki etkisi RTCA cihazında hücre proliferasyonu ölçümleri yapılarak araştırıldı.

Bulgular: Sonuçlarımıza göre 2, 4 ve 8 μg’lık LPS konsantrasyonlarını hücre bölünmesini inhibe ederek hücreleri kararlı duruma yönlendirdiğini gösterdi. 1 μg ’lık LPS konsantrasyonu hücreleri mitotik faza sürüklerken daha düşük LPS konsantrasyonlarının ise hücre proliferasyonu üzerinde bir etki göstermedi.

Sonuç: Bu çalışmadaki sonuçlara göre LPS konsantrasyonlarının hücre proliferasyonu üzerinde farklı etkilerinin olduğu ve deneysel çalışmalardan önce LPS konsantrasyonlarının optimize edilmesi gerektiği gösterilmiştir.

Re-evaluation Of LPS Concentrations On The 293T Human Renal Cell Line

Abstract

Objective: The inflammatory responsiveness of the cells to Lipopolysaccharides (LPS) is commonly used for in vitro experiments. However, the correct dose of the LPS for cell line experiments is elusive. The LPS concentration that gives the maximal response is a critical point of in vitro inflammatory experiments. The aim of this study was to reevaluate the concentration dependent effect of LPS on the 293T human renal cell line.

Methods: We evaluated the cell-detachment assay of LPS-stimulated 293T cell line monitored by xCELLigence Real-Time Cell Analyzer (RTCA) system. We applied increasing concentration of LPS followed by Roche xCELLigence Instrument based on the Real-Time Cell Analysis System.

Results: Our results demonstrated that the 2, 4 and 8μg of LPS inhibit cell division which diverts cells to a steady-state phase, 1 μg acts as mitogen. Lower concentrations are no effect on cells.

Conclusion: These work showed that LPS concentrations had various effects on cell proliferation and need to be estimated for each experiment before carry out the experiments.
