Freeze‐dried human serum albumin improves the adherence and proliferation of mesenchymal stem cells on mineralized human bone allografts

Abstract: Mineralized scaffolds are widely used as bone grafts with the assumption that bone marrow derived cells colonize and remodel them. This process is slow and often unreliable so we aimed to improve the biocompatibility of bone grafts by pre-seeding them with human mesenchymal stem cells from either bone marrow or dental pulp. Under standard cell culture conditions very low number of seeded cells remained on the surface of freeze-dried human or bovine bone graft or hydroxyapatite. Coating the scaffolds with fibro… Show more

“…255,256 Among other bioderived polymers, some have been used to encapsulate antibiotics, such as albumin 257,258 or dextran, 259 but have not been reported in bone-related experimental trials, except in combination with more mechanically stable, inorganic phases. Albumin coatings around allografts, for example, improved cell adhesion and proliferation 260 and enhanced bone healing, 261 whereas the use of dextran as a porogen in PMMA beads boosted the release of vancomycin, daptomycin, and amika-cin. 262 Conversely, silk fibroin coating around PCL microspheres managed to reduce the initial burst release of vancomycin and extend the timeframe of its release.…”

“…Ezen a hiányosságon kívántunk javítani az albuminbevonattal. Esetünk példa arra, hogy az allograft felszíni kezelése javítja az átépü lési készséget [13,14,15,19]. Szintén a korábbi adatokat alátámasztó tény -mármint hogy az osteoporosis, illetve az osteolysis okozza az aszeptikus lazulással járó szövőd-ményeket -, hogy esetünkben is a graft-csont találkozás alatt történt a tibia törése, aminek oka természetesen a trauma volt, de a lokalizáció az osteoporosis követ-kezménye.…”

“…Korábbi scanning elektronmikroszkópos vizsgálataink során jelentős en tömörebb szerke zetűnek találtuk a -TCP-t, össze hason lítva a liofi lizált szarvasmarha csonttal és humán allografttal. 18 A -TCP tömör szerkezete és a kollagén-fi lamentumok hiánya együttesen ma gyarázhatja a jelentősen nagyobb mik ro keménységet.…”
