由于缺乏功能性体外模型,预防或治疗唾液腺功能障碍的治疗方法的发展受到限制。具体来说,唾液腺分泌表型的关键标志物在体外迅速下调。在这里,我们利用唾液腺组织芯片模型进行实验设计(DoE)方法来测试七种可溶性线索的组合,这些线索先前被证明可以维持或改善唾液腺细胞功能。这种方法使用统计技术来提高因子组合的效率和准确性。doe设计的培养条件改善了唾液腺功能的标志物。数据显示,EGFR抑制剂EKI-785维持了腺泡细胞关键转录因子Mist1的相对mRNA表达,而FGF10和neurturin则促进了参与分泌的通道蛋白Aqp5和Tmem16a的mRNA表达。Mist1 mRNA表达与分泌功能增加相关,包括钙信号和粘蛋白(PAS-AB)染色。总之,本研究表明,使用DoE方法可以有效地优化培养基条件以支持体外分泌功能。
The development of therapies to prevent or treat salivary gland dysfunction has been limited by a lack of functional in vitro models. Specifically, critical markers of salivary gland secretory phenotype downregulate rapidly ex vivo. Here, we utilize a salivary gland tissue chip model to conduct a design of experiments (DoE) approach to test combinations of seven soluble cues that were previously shown to maintain or improve salivary gland cell function. This approach uses statistical techniques to improve efficiency and accuracy of combinations of factors. The DoE-designed culture conditions improve markers of salivary gland function. Data show that the EGFR inhibitor, EKI-785, maintains relative mRNA expression of Mist1, a key acinar cell transcription factor, while FGF10 and neurturin promote mRNA expression of Aqp5 and Tmem16a, channel proteins involved in secretion. Mist1 mRNA expression correlates with increased secretory function, including calcium signaling and mucin (PAS-AB) staining. Overall, this study demonstrates that media conditions can be efficiently optimized to support secretory function in vitro using a DoE approach.
