    Primary open-angle glaucoma is a prevalent type of degenerative eye disease that results in lifelong blindness, and its critical pathogenic cause is trabecular meshwork (TM) dysfunction or decreased TM cellularity. Considering that TM develops from neural crest cells (NCCs), we investigate the potential of human embryonic stem cell (hESC)-derived NCCs transplantation for TM regeneration. We used a chemically defined method to induce the differentiation of ... ...点击完成人机验证后继续浏览

    原发性开角型青光眼是一种导致终生失明的退行性眼病,其关键病因是小梁网(TM)功能障碍或小梁细胞数量减少。考虑到TM由神经嵴细胞(NCCs)发育而来,我们研究了人胚胎干细胞(hESC)衍生的NCC移植用于TM再生的潜力。我们使用化学定义的方法诱导NCC分化,并将1.0 × 106 hESC衍生的NCC与100 μmol/L Y-27632混合后注入兔前房中。通过TonoPEN AVIA、裂隙灯显微镜、双重免疫荧光染色和光学相干断层扫描检查了细胞移植兔眼的内眼压(IOP)、TM及角膜变化。在5天诱导过程中,hESC衍生的NCCs表现出均匀分化,并表达了典型的神经嵴标记物HNK-1、P75、SOX10和AP-2α。将hESC衍生的NCCs注射到NOD/SCID小鼠的腹股沟或腋下区域后,未发现畸胎瘤形成。当在前房内注射时,hESC衍生的NCCs可以在兔眼移植7天后整合到TM组织中,并表达成熟的TM细胞标记物Aqp1Chi3l1Timp3 。2周内,IOP和中央角膜厚度基本保持在正常水平。经过5周的细胞移植,未观察到兔眼注射hESC衍生NCCs后出现显著不良反应。我们的研究结果表明,通过前房内注射,hESC衍生的NCCs可以整合入TM组织,并分化为成熟的TM细胞,展示了治疗TM功能障碍、用于青光眼治疗的新潜在疗法。
