Methods BMSCs isolated from rabbit iliac bone marrow were culture-expanded in vitro. The injectable tissue-engineered bone constructed from autologous PRP, FG, and BMSCs was cultured in vitro, and its biological characteristics were observed including the time of gel formation, histological features, seed cell survival and microscopic structures. Results The constructed injectable tissue-engineered bone began gel formation within 20 to 30 s, and after a week-long culture, the gelatine began to degrade, and numerous well viable fusiform cells could be seen to adhere to the bottom of the Petil dish, Scanning electron microscopy identified globular and olivary cells embedded in the fibrin glue, and numerous small particles could be seen around of the cells.
