peptides from phage display library modulate gene expression in mesenchymal cells and potentiate osteogenesis in unicortical bone defects

Zwei neuartige synthetische Peptide beschleunigen Knochenbildung und können mithilfe einer Kollagen-Matrix. Das Ziel dieser Studie war es, die Auswirkungen auf die Knochenheilung in einem unikortikale Defekt-Modell zu untersuchen. Behandlung von mesenchymalen Zellen führte zu einer Zunahme der alkalischen Phosphatase-Aktivität zeigte Knöllchenbildung von den Zellen und erhöht die Expression von Genen für RUNX2, osterix, Bonesialoprotein und Osteocalcin. Ein Kollagenschwamm mit Peptid gefördert Reparatur von Knochendefekten getränkt, während die Kontrolle war weniger wirksam. Die Ergebnisse aus dieser Studie zeigten, dass mesenchymale Zellen mit Peptid in vitro behandelt Richtung Osteogenese zu unterscheiden, und, dass Peptide in vivo geliefert mit einem Kollagenschwamm die Reparatur von unikortikale Mängel zu fördern.
