该方案描述了坏死性小肠结肠炎(NEC)的 体外 模型,可用于疾病发病机制的机制研究。它的特点是微流控芯片,其中植入了源自人类新生儿肠道、内皮细胞和患有严重 NEC 的新生儿肠道微生物组的肠道类生物。

该领域的研究具有挑战性,因为坏死性小肠结肠炎的病理生理学很复杂,而这种复杂性并没有反映在许多常用的体外模型中。使用人体样本的研究通常受到样本量小和肠道手术时获得的样本稀有性的限制。我们的目标是确定导致早产儿发生NEC的机制,并确定新的治疗策略。

NEC-on-a-Chip系统通过更紧密地反映新生儿肠道的生理机能,改进了以前的模型。在这个模型中,我们将患者来源的肠道类器官、内皮细胞和来自患有严重 NEC 的新生儿的微生物组结合到微流控芯片上。
