项目摘要

Bone marrow stromal cells taken from EGFP transgenic mice were sorted by magnetic beads with surface markers of Sca-1 and Thy-1. The cells were then co-cultured on organotopic hippocampal slice or with neuronal cell feeder in dish. On hippocampus, both Sca-1 and Thy-1 positive cells showed 4- 8 folds higher potential to show neuron-like morphology than negative cells. In dish, negative cells fewly survived but each positive cells survived and showed neuron-like differentiation. In both culture condition, retinoic acid supplement accelerate differentiation. Differentiated Sca-1 and Thy-1 positive cells were immunohistochemically GFAP- and NeuN-negative but nestin-, neurofilament and NSE-positive. Neuron-like differentiation of bone marrow cells can be enhanced by selection using cell surface proteins.
用磁珠和SCA-1和THY-1的表面标记物对从EGFP转基因小鼠采集的骨髓基质细胞进行排序。然后将细胞共培养在有机体海马切片或与DISH中的神经元细胞进料器中。在海马上,SCA-1和THY-1阳性细胞均显示出比阴性细胞更高的4-8倍倍显示神经元样形态的潜力。在DISH中,阴性细胞几乎无法存活,但每个阳性细胞都存活并显示出神经元样分化。在这两种培养条件下,视黄酸补充剂加速分化。分化的SCA-1和THY-1阳性细胞是免疫组织化学的GFAP和NEUN阴性,但Nestin-,神经丝和NSE阳性。通过使用细胞表面蛋白的选择,可以增强骨髓细胞的神经元样分化。
