| 摘 要： | 本实验从新生大鼠嗅球中分离出嗅成鞘细胞，进行体外培养。运用RT—PCR方法检测甘丙肽及其受体在体外培养的嗅成鞘细胞中的表达；运用MTT法检测甘丙肽及其受体激动剂、拮抗剂对嗅成鞘细胞增殖的影响。结果显示：嗅成鞘细胞表达甘丙肽(GAL)及其受体GalR2，而不表达其他两种受体GalRl和GalR3；甘丙肽及两种受体激动剂GALl-11和GAL2-11能够明显地抑制体外培养的嗅成鞘细胞的增殖，这一效应可被非特异性甘丙肽受体拮抗剂M35所阻断。

| Abstract: | Olfactory ensheathing cells (OECs) were isolated from newborn rat olfactory bulb and cultured in vitro. RT-PCR was used to determine the expression of galanin and it's receptors in these cells. MTT analysis was used to detect the effects of galanin and agonist, antagonist of galanin receptors on the proliferation of OECs. Results show that OECs express mRNAs for galanin and GalR2 but not for two another receptors, GalR1 and GalR3. In addition, galanin and two receptor agonists, GAL1-11 and GAL2-11, can significantly inhibit the proliferation of OECs. But the influence can be blocked by M35, nonspecific antagonist of galanin receptors. |
