In an in vitro experiment examining femoral head samples, we found that the RNA level of myocardial infarction-associated transcript (Miat) in necrotic tissue was much higher than that in normal tissue and that silencing endogenous lncRNA-Miat could promote the osteogenesis of rat bone marrow mesenchymal stem cells (rBMSCs). Here, MIAT is linked to myocardial infarction.
