Background: Cardiomyocyte enrichment strategies so far have not yielded scalable cardiac specific cell type. More so, the current data is restricted to embryonic stem cells (ESCs)/induced pluripotent stem cells (iPSCs), wherein the use of viral vectors is fraught with increased risk during clinical use. Herein, we profiled time-dependent gene/protein expression patterns across the cardiac ectoderm, endoderm, and mesoderm for isolating cardiac precursors from human adipose derived stem cells (hADSC). Methods: Direct cardiac differentiation of hADSCs was carried out with 5-azacytidine and basic fibroblast growth factor (bFGF) in a one month long culture. The cells were periodically harvested, analyzed for unique persistent markers and their inherent regulation using quantitative polymerase chain reaction (qPCR), flow cytometry, immunoblot and immunocytochemistry assays. The identified markers were super paramagnetic iron oxide nanoparticle (SPION) tagged for segregation by magnetic activated cell sorting (MACS) and further evaluated their differentiation potential and checked for the purity by flow cytometry. Results: The results demonstrated pronounced up-regulation of mesodermal and mature cardiac lineage markers at three weeks, while there was a down-regulation of pluripotent stem cell markers. This perhaps could be attributed to de-differentiation in maintaining the cardiac phenotype. However, signal regulatory protein alpha (SIRPA) and kinase domain receptor (KDR) persisted all through the culture period of one month, making them the most relevant and reliable cardiac specific markers. Dual labeling of these markers to SPION for cardiomyocyte enrichment by MACS column yielded cardiomyogenic-like cells in differentiation cultures with several functional positive markers. Conclusions: Thus, SIRPA and KDR together provide cues in the enhancement and up-scaling of cardiomyocyte production in the cell replacement therapy. Read more. . .
