Abstract:
?Objective: To study the methodology of the culture of Schwann cells derived from degenerated peripheral nerve. Method: Sciatic nerve of adult rats was surgically cut. 14 days after operation, the degenerated nerve tissue was obtained and treated with trypsin and collagenase typeⅡ to prepare single cell suspension,the cells were purified by different speed of attachment and digestion, and incubated on ZQ membrane in the presence of 10 -5 mol/L cytosine arabinoside. The growth of the cells of passage 2 was studied by MTT assay. Schwann cells were identified with anti S100 immumohistochemistry. Results: The cultured cells were spindly in shape and 95% of them were S100 positive. The population doubling time of passage 2 cells was 72 h.The cells attached and stretched on ZQ membrane as well as on the culture vessel surface. Conclusion: Schwann cells can be cultured and purified by predegeneration of the peripheral nerve,different speed of attachment and digestion and the presence of cytosine arabinoside. The cells can grow well on ZQ membrane.
