dc.description.abstract | There is a continuous search of new implant materials with better biocompatibility and physiological properties than the current commercially pure Ti and Ti-6Al-4V alloys. Gamma titanium aluminide (γTiAl) appears to have excellent potential for bone repair and replacement. The response to γTiAl implant is expected to be similar or better than those of Ti-6Al-4V. Human fetal osteoblast cells were cultured on the surface of γTiAl and Ti-6Al-4V discs with variable surface roughness for both SEM and immunofluorescent analysis to detect the presence of collagen type I and osteonectin, proteins of the bone extracellular matrix. Results show that cell growth and attachment on γTiAl was normal compared to that of Ti-6Al-4V, suggesting that γTiAl is not toxic to osteoblasts. Normal growth and the presence of collagen type I and osteonectin was observed on γTiAl and Ti-6Al-4V. The results obtained suggest γTiAl is biocompatible with the osteoblasts. | en_US |

Gamma titanium aluminide (γTiAl), aparenta tener excelente potencial para reparar y reemplazar huesos. Se espera que la respuesta a implantes de γTiAl sea similar o mejor que la de Ti-6Al-4V. Células de osteoblastos fetales humanas fueron cultivadas en la superficie de discos de γTiAl y Ti- 6Al-4V con rugosidades variables para realizarles estudios de MER y análisis de inmunoflorescencia para detectar la presencia de colágeno tipo I y osteonectina, proteínas de la matriz extracelular del hueso. Los resultados muestran que el crecimiento celular y la adhesión en γTiAl eran normales al compararlos con células creciendo en Ti-6Al-4V, sugiriendo que γTiAl no es tóxico para los osteoblastos. El crecimiento normal y la presencia de colágeno tipo I y osteonectina fue observado en células cultivadas en γTiAl y Ti-6Al-4V. Los resultados obtenidos sugieren que γTiAl es biocompatible con los osteoblastos.. | en_US |
