PRP’nin mezenkimal kök hücre çağırıcı etkisi ile yağ grefti sağkalımında artış: Uygulama tekniklerinin in vitro ve in vivo çalışması

Amaç: Yağ greftinin kalıcılığını artırmak için trombositten zengin plazma (PRP) veya mezenkimal kök hücre eklenmesi en çok kabul gören yöntemlerdir. Ancak zamanlama ve bölge açısından kök hücrenin mi yoksa PRPnin mi etkisinin daha çok gözlendiği konusunda bir fikir birliği yoktur. Sağkalımı artırmak için yağ grefti ile kombine edilecek PRP'nin uygulama yöntemi ve lokalizasyonunun sunulması amaçlanmaktadır. Gereç ve Yöntem: in vitro çalışma: Yağ greftleri PRP içeren besiyerinde tutulmuştur. Yağ greftinden Petri kaplarına hücre çıkışı her gün incelendi. Ortama en fazla sayıda kök hücre alma zamanı belirlendi (10. gün). in vivo çalışma: Sekiz grup sıçana, yağ greftlerinin alıcı veya verici alanlarına farklı konsantrasyonlarda PRP uygulandı. On gün sonra alıcı bölgeye yağ greftleri transfer edildi. Transferden doksan gün sonra histopatolojik inceleme ve immünohistokimyasal boyama yapıldı. Bulgular: Alıcı alana tam doz PRP uygulanan grup en yüksek hücresel bütünlük ve damarlanma gösterdi (p

Increased fat graft survival with mesenchymal stem cell recruiting effect of PRP: in vitro and in vivo study of application techniques

Aim: Adding platelet-rich plasm (PRP) or mesenchymal stem cells are the most accepted methods to increase fat graft’s permanence. However, there is no consensus on timing and whether the effect of stem cells or PRP is observed more in the recipient area or in the donor area. It is aimed to present the application method and localization of PRP to be combined with fat graft to increase the survival. Material and Methods: in vitro part: Fat grafts were kept in a medium containing PRP. Cell output from the fat graft to the Petri dishes was examined every day. The time to recruit the maximum number of stem cells to the medium was determined (day 10). in vivo part: Eight group of rats were received PRP in different concentrations either to recipient or donor areas of fat grafts. After ten days, fat grafts were transferred to the recipient area. Ninety days after the transfer, histopathological examination and immunohistochemical staining were performed. Results: The group which had received the full-dose PRP to the recipient area showed the highest cellular integrity and vascularity (p
