摘要:

如何增强移植的神经干细胞在受损脊髓处存活是干细胞移植治疗脊髓损伤成功的一个先决条件。
韩国亚洲大学Byung Gon Kim教授研究显示,通过密集的康复训练不仅能够通过促进移植的神经干细胞存活,而且可以提高神经干细胞的多种分化功能,增强神经干细胞移植的治疗效果。Kim教授发现,康复训练增加了神经干细胞分化为神经细胞或少突胶质细胞的百分比,IGF-1信号参与神经干细胞存活和神经干细胞移植和康复训练在功能性运动恢复中收到协同效应。这些发现具有重要的临床意义,Kim教授指出,细胞移植前后密集的康复计划已经被纳入正在进行的细胞治疗临床试验中。

Abstract:

Traumatic injuries to spinal cord elicit diverse signaling pathways leading to unselective and complex pathological outcomes: death of multiple classes of neural cells, formation of cystic cavities and glial scars, disruption of axonal connections, and demyelination of spared axons, all of which can contribute more or less to debilitating functional impairments found in patients with spinal cord injury. The multitude of pathobiological processes involved in spinal cord trauma may make it highly challenging to develop a clinically meaningful therapeutic approach targeting only a specific molecule or signaling pathway. A hopeful alternative might be a cell therapy, especially a transplantation approach using neural stem cells (NSC) with a clear potential to differentiate into various neural cell types. Provision of NSCs with capacity to differentiate into mature neural cells can ideally replace lost segmental neurons and dying oligodendrocytes around surviving axons. Furthermore, NSCs secrete various growth factors that provide protective or pro-regenerative effects. It has been also demonstrated that NSCs can exert powerful modulatory effects on immune cells ameliorating secondary degenerative processes.
