概括

在老鼠的骨盆手术后,人类多能干细胞衍生的神经细胞成功修复了神经损伤. 这种疗法通过再生骨盆神经和改善阴茎组织健康来恢复勃起功能.

科学领域:

再生医学是一种再生医学.
神经科学是一个神经科学.
泌尿器科泌尿器科泌尿器科泌尿器科

背景情况:

盆腔手术经常导致神经损伤,导致勃起功能障碍 (ED),治疗选择很少.
主要的盆腔 (MPG) 对于勃起功能至关重要,并且经常受伤.
圣神经顶 (NC) 细胞是MPG神经元和质细胞的胚胎原始细胞,为神经修复提供了潜在的来源.

研究的目的:

开发和测试人类多能干细胞 (hPSC) 衍生的神经NC细胞,用于治疗神经性ED.
为了评估神圣NC细胞移植在MPG损伤的老鼠模型中的疗效.

主要方法:

从hPSCs中生成一个稳定,可扩展的圣骨NC细胞群.
将这些细胞移植到MPG受压伤的老鼠体内.
评估细胞移植和勃起功能恢复.

主要成果:

移植的圣骨NC细胞成功移植并显著改善勃起功能 (增加ICP/MAP比率).
MPG修复涉及分化为神经元/质细胞和神经营养因子 (BDNF,GDNF,NGF) 的分泌.
恢复自主内置导致亡/纤维化减少,并改善阴茎光滑肌肉和内皮完整性.

结论:

来自hPSC的圣体NC细胞为神经性ED提供了一种新的治疗方法.
这一策略恢复了骨盆自主神经的结构和功能.
治疗涉及神经元差异化和持续的神经营养支持勃起康复.

Male Sexual Response: Erection & Ejaculation

Male Sexual Response: Erection & Ejaculation

Sexual stimulation can take various forms, such as physical touch and visual or auditory cues. When this happens, the parasympathetic reflex in the sacral portion of the spinal cord is activated. This reflex stimulates the release of nitric oxide (NO), which then dilates the arterioles in the penis, increasing blood flow to the erectile tissues - the corpora cavernosa and corpus spongiosum.
The blood filling the erectile tissues compresses the veins, which helps to prevent blood from leaving...

Neurogenesis and Regeneration of Nervous Tissue

Neurogenesis and Regeneration of Nervous Tissue

In the CNS, neurogenesis, the birth of new neurons from stem cells, is limited to the hippocampus in adults. In other regions of the brain and spinal cord, neurogenesis is almost non-existent due to inhibitory influences from neuroglia, especially oligodendrocytes, and the absence of growth-stimulating cues. The myelin produced by oligodendrocytes in the CNS inhibits neuronal regeneration. Furthermore, astrocytes proliferate rapidly after neuronal damage, forming scar tissue that physically...
