Abstract

Objective: Mesenchymal stem cells (MSCs) exist in the site of atrophic non-union fracture. The aim of this study was to evaluate the osteogenic potency of MSCs in order to have a better understanding of the unclear pathophysiology of atrophic non-union fracture Methods: This is an in vitro experimental study. Sample was obtained from the non-union site of a patient with a 6-years-history of atrophic non-union fracture of right femur. The MSCs was isolated from the fracture site and was cultured in the growth medium. Confirmation of the MSCs was performed and then osteogenic differentiation was performed in mono-layered MSC grown in both home-made and commercial osteogenic media. To evaluate the osteogenic differentiation, we performed Alizarin red staining and colorimetric assay for alkaline phosphatase (ALP). Results: From Alizarin red staining, most cells in the osteoblast medium were stained red by the staining. The result of colorimetric assessment of ALP shows that peak concentration was reached after 4 minutes in osteogenic group and control group. Conclusion: The presence of ALP activity and positive Alizarin red staining in our study showed that MSCs stem cells obtained from site of atrophic non-union is capable to be differentiated into osteogenic cells. .

Abstract

Amaç: Bu çalışmanın amacı atrofik birleşmemiş kırık patofizyolojisini daha iyi anlamak için bu bölgelerdeki mezenkimal kök hücrelerinin (MKH) osteojenik potansiyelini araştırmaktır. Yöntemler: Çalışmamız in vitro deneysel bir çalışmadır. Altı yıllık sağ femurda atrofik birleşmemiş kıık öyküsü bulunan bir hastanın kırık yerinden örnek alındı. Mezenkimal kök hücreler kırık bölgesinden izole edildi ve besiyerine kültüre ekildi. Mezenkimal kök hücrelerinin doğrulanma ve daha sonra osteojenik farklılaşması, tek tabakalı MKH ve ticari osteojeik ortamda yapıldı. Osteojenik farklılaşmayı değerlendirmek için Alizarin kırmızı boya ve alkalen fosfataz için kolorimetrik test yapıldı. Bulgular: Alizarin boyası ile osteoblastik ortamdaki hücrelerin çoğu kırmızıya boyandı. Alkalen fosfatazın kolorimetrtik değerlendirilmesi osteojenik ve kontrol grubunda dört dakika sonra pik konsantrasyona ulaştı. Sonuçlar: Çalışmamızda alkalen fosfataz aktivitesi varlığı ve pozitif Alizarin kırmızı boyanması atrofik birleşmemiş bölgeden alınan MKH\'ların osteojenik hücrelere farklılaşma potansiyeli olduğunu gösterdi.

• In our previous study, we revealed the existence of
• mesenchymal stem cells in atrophic non-union frac
• ture site [8]. However, in our, we did not evaluate
• the osteogenic potency of those cells in the study.
• In this study, we evaluated the osteogenic potency
• of mesenchymal stem cells in the site of atrophic
• non-union fractures.
• Characterization of cells obtained from the site
• of atrophic non-union fracture confirmed the pres
• ence of mesenchymal stem cells. The cells that we
• obtained were able to adhere to plastic in standard
• culture condition, positive expression on CD 105,
• CD 73, CD 90 for at least 95%, negative expression
• of CD 45, CD 34, CD 14 or CD 11b, CD 79a, and HLA-DR [9].
• Despite similar constituents, we found failure of
• our home-made medium to induce differentiation of
• MSCs into osteogenic cells. [10] All cells died before
• 5 weeks and none was left for further evaluation.
• The failure might due to the imprecise composition
• of the medium that influence the milieu. Further re
• searches must be done to evaluate the effect of this
• homemade osteogenic medium upon its capabil
• ity in inducing osteogenic differentiation of MSCs.
• Addition of various chemical substances had been
• reported to increase the success of osteogenic dif
• ferentiation [11-13].
• Osteogenic differentiation of MSCs can be
• characterized by various technique, depending on
• the development stage of the cells; cells prolifera
• tion, matrix maturation, and matrix mineralization [14-15].
• During cells proliferation, several extracellular
• matrix proteins can be detected, such as procol
