Recently, the bone marrow cell secretome was screened, and after bioinformatic analysis was used to eliminate genes characterized or predicted to encode potential non‐secreted proteins, 150 genes were analysed18; 2 proteins, C19orf10 (“myeloid‐derived growth factor”) and C1orf54, were found to possess potential secreted protein functions, and further investigation revealed that C19orf10 promoted angiogenesis and cardiomyocyte survival after myocardial infarction. Here, MYDGF is linked to myocardial infarction.
