Abstract: Objective: To study the effects of indirect co-culture of rabbit dental pulp stem cells (rDPSCs) and rabbit schwann cells (rSCs) in vitro on each other's proliferation and the possibility of rSCs inducing rDPSCs into neural differentiation. Methods: The indirect co-culture system of rSCs/rDPSCs was constructed by Transwell indirect co-culture system, and MTT method was adopted to detect the cells' proliferation. Immunofluorescence staining and Western bolt were used to study the expression of S-100β and NF-H and the possibility of rSCs to induce neural differentiation of rDPSCs. Results: When rDPSCs and rSCs were indirectly co-cultured in a 1∶2 ratio for 5 days, rDPSCs could facilitate the proliferation of rSCs (P<0.05), and rSCs also had obvious effect on the proliferation of rDPSCs (P<0.05). After indirect co-culturet with rSCs for 7 days and 14 days, rDPSCs became neuron-like cells, S-100β and NF-H were expressed and both presented a higher level after 14 days (P<0.01). Conclusion: In the indirect co-culture system of rDPSCs and rSCs, rDPSCs and rSCs can significantly promote each other's proliferation after 5 days, while rSCs can induce the neural differentiation of rDPSCs.
