Transcriptional analysis and live-cell imaging are a powerful tool to investigate the dynamics of complex biological systems. In vitro expanded porcine oral mucosal cells, consisting of populations of epithelial and connective lineages, are interesting and complex systems for study via microarray transcriptomic assays to analyze gene expression profile. The transcriptomic analysis included 56 ontological groups with particular focus on 7 gene ontology groups that are related to the processes of differentiation and development. Most analyzed genes were upregulated after 7 days and downregulated after 15 and 30 days of in vitro culture. The performed transcriptomic analysis was then extended to include automated analysis of differential interference contrast microscopy (DIC) images obtained during in vitro culture. The analysis of DIC imaging allowed to identify the different populations of keratinocytes and fibroblasts during seven days of in vitro culture, and it was possible to evaluate the proportion of these two populations of cells. Porcine mucosa may be a suitable model for reference research on human tissues. In addition, it can provide a reference point for research on the use of cells, scaffolds, or tissues derived from transgenic animals for applications in human tissues reconstruction.
转录分析和活细胞成像技术是研究复杂生物系统动态变化的有力工具。体外扩增的猪口腔黏膜细胞由上皮和结缔组织谱系群体组成,是通过微阵列转录组分析来分析基因表达谱的有趣且复杂的研究系统。转录组分析包括56个本体论组,特别关注与分化和发育过程相关的7个基因本体论组。大多数分析的基因在体外培养7天后上调,在15天和30天后下调。然后将进行的转录组分析扩展到包括对体外培养期间获得的微分干涉对比显微镜(DIC)图像的自动分析。对DIC成像的分析能够在体外培养的7天内识别角质形成细胞和成纤维细胞的不同群体,并且可以评估这两种细胞群体的比例。猪黏膜可能是用于人体组织参考研究的合适模型。此外,它可以为研究使用来自转基因动物的细胞、支架或组织在人体组织重建中的应用提供参考点。
