OBJECTIVE: To investigate a new way to yield plenty of high purity olfactory ensheathing cells (OECs) and its biocompatibility with appropriate scaffolds. METHODS: OECs were prepared from neonatal Wister rats and co-cultured with poly [LA-co-(Glc-alt-Lys)] (PLGL). Its contact angle, adherent rate, and activity rate were tested. RESULTS: The contact angle of poly (D, L-lactic acid) (PDLLA) (84.5 degree+/-1.5 degree) was significantly higher than that of PLGL (52.6 degree+/-0.8 degree), the adherent rate of PLGL (80%) was significantly higher than that of the PDLLA (57%), and the activity rate of PLGL (88%) was much higher than that of the PDLLA (76%). CONCLUSION: PLGL possesses better hydrophilicity and biocompatibility than PDLLA, and it can provide a better cell growth circumstance which is helpful for the effective treatment of nerve injury.
