OBJECTIVE: To culture Schwann cells (SCs) and human hair keratins (HHKs) for artificial nerve bridge construction.
METHODS: SCs were purified by primary culture and labeled with BrdU, which were then cultured with HHKs decorated by ECM. The artificial nerve bridge was implanted into the defect of sciatic nerve, beneath the skin, and in the skeletal muscles of SD rat, respectively. The morphology of the SCs cultured with HHKs was monitored by inverted microscope and evaluated by immunocytochemical staining. Growth of BrdU-labeled SCs in vivo was observed by immunocytochemical staining on paraffin sections.
RESULTS: In vitro cultured SCs were capable of adhering to HHKs and grew well four weeks after implantation. The HHK component in the artificial nerve bridge underwent degradation in the defect of the sciatic nerve, beneath the skin, and in the skeletal muscles of SD rat, and SC survival and proliferation were verified.
CONCLUSION: SCs can survive in three-dimensional culture with HHKs for construction of artificial nerve bridge to repair nerve defects.
