Abstract
The study of the secretome of different cell types has gained prominence over the years due to its role in understanding the cell microenvironment and possible uses in acellular therapies. Approaches in this field include proteomic characterizations of the secretomes as well as evaluating their potential to induce cell and tissue responses. Here, we present the mass spectrometry proteomics data from a characterization of the secretome of cardiac resident stromal cells (CRSCs) and dermal fibroblasts in order to compare their compositions. To evaluate the potential for cell proliferation, differentiation, migration, and adhesion, in vitro assays were performed and analyzed using a high-content imaging system. For each assay, specific analysis strategies were developed to quantify the generated data. These datasets provide insights into the differences and similarities between secretomes from different cell sources. It also describes methodologies for analyzing images from different in vitro assays using high-throughput automated imaging.
