English Abstract:
  【Abstract】 Objectives: To investigate the differentiation of bone mesenchymal stem cell(BMSC) induced by co-culturing with olfactory ensheathing cell(OEC). Methods: BMSC and OEC were isolated and cultured from 20 5-6-week-old 100g male rats. BMSC was isolated from rat femur, and OEC was isolated from rat olfactory epithelium. The co-culture system used was 6-well 0.4m Transwell co-culture system. The third generation cells were co-cultured within this system at a density of 2×104/cm2 and 3×104/cm2 for OEC and BMSC respectively. BMSC was processed for immunofluorescence and flow cytometry at 7d and 14d for the specific marker Nestin, neuronal class Ⅲ β-tubulin(Tuj-1) and glial fibrillary acidic protein(GFAP). Results: Immunocytochemistry showed BMSC could express Nestin, Tuj-1 and GFAP after 7d and 14d co-culture. Flow cytometry revealed that the positive rate of Nestin, Tuj-1 and GFAP was 46.3%, 76.5% and 23.2% after 7d co-culture; and the positive rate of Nestin, Tuj-1 and GFAP was 27.7%, 89.1% and 50% after 14d co-culture. Conclusions: BMSC can efficiently differentiate into neural-like cells when coculturing with OEC.
