Abstract：BACKGROUND:Some scholars believe that anesthesia can improve the quality of cord blood separation and colection, and subarachnoid block is commonly used in cesarean section, but there is no research on the influence of subarachnoid block on differentiation potential of mononuclear cels into neural stem cels and astrocytes. <br> OBJECTIVE: To study the influence of subarachnoid block on differentiation potential of mononuclear cels in the cord blood of neonates into neural stem cels and astrocytes. <br> METHODS:Mononuclear cels isolated from 20 neonates delivered spontaneously and 20 neonates born by cesarean delivery undergoing subarachnoid block were culturedin vitro, acting as control group and study group. After delivery, cord blood samples were taken to isolate and culture mononuclear celsin vitro. After 3 days of routine culture, the cels were subject to non-induced culture and induced differentiation into neural stem cels. The cultured cels were identified by the cellmakers Nestin and glial fibrilary acidic protein with immunohistochemistry identification. <br> RESULTS AND CONCLUSION:The Nestin and glial fibrilary acidic protein showed no difference between the two groups after induced differentiation (P > 0.05), indicating subarachnoid block has no impact on the differentiation of mononuclear cels in the cord blood from neonates into neural stem cels and astrocytes.
