Abstract
Objective: Investigation of the cells cultivated within large porous scaffolds is problematic. This study aimed to develop scale-down culture models (SDCMs) for high throughput microscopic analysis of the infiltrated cells. Methods: Due to the advantages of biocompatibility and transparency, commercial glass capillaries with different lengths (5-80mm) and inside diameters (0.3, 1.0, 1.5, 1.7, 2.0mm) were tailored and situated in petri-dishes to mimic the interconnected pore structures within thick porous scaffolds. For the ease of in situ cell assessment, both horizontal and vertical SDCMs were developed and integrated with conventional microscopic technologies. Results: Evaluation experiments using migratory human dermal fibroblasts indicated that these SDCMs were able to simulate varying microenvironments surrounding infiltrated cells within large scaffolds. As both individual and aggregated cells at different parts of the capillaries were imaged noninvasively with sufficient high resolutions, it was feasible to track the dynamic tissue formation processes without sacrificing the delicate samples. Conclusion: This research demonstrated that these SDCMs could rapidly provide reliable data for the mechanistic understanding of various overarching factors that contribute the colonization of the infiltrated cells in large porous scaffolds.
