Abstract ADMSCs were isolated from subcutaneous adipose tissue, characterized and cultured in vitro. GFP-labeled ADMSCs can grow and proliferate well on the Atelocollagen scaffolds, and induced by 5-aza the cells can differentiate into cardio-like cells. 3D cultured ADMSCs on Atelocollagen scaffolds were transplanted into mice ischemia myocardium, and have good biocompatibility with host cardio tissue. Graphical Abstract

1 Introduction Over the past decades, a variety of stem cells have been used in clinical trials. And again, stem cell transplantation, has been a new method for the treatment of myocardial infarction (MI), a

severe clinical condition. In recent years, three types of biological materials have mainly been used for myocardial tissue engineering research: natural materials, synthetic materials, and composite materials. Natural materials mainly include collagen, coral, amino dextran, chondroitin sulfate, gelatin, sodium alginate, fibrin gel, etc. [1–3]. Synthetic materials refer to polyurethane, polyglycolic acid (PGA), polylactic acid (PLA),

polyhydroxybutyrate, etc. [4–6]. Composite materials represent chitosan, polylactic acid and multi-walled carbon nanotube fibers, etc. [7]. Ideal myocardial tissue engineering scaffolds materials should be characterized by: non-toxic and good biocompatibility; easy to form 3D structure; high porosity; good surface activity for cell adsorption; biodegradability and plasticity. Atelocollagen is presently found to be equipped with the abovementioned characteristics and can be used as a tissue filler and for intervertebral disk regeneration culture scaffolds [8]. According to our previous research, Atelocollagen scaffolds could be perfectly combined with neonatal and adult rat cardiomyocytes. In addition, pulsatile 3D myocardial tissue blocks were cultured [9]. Compared to mesenchymal stem cells (MSCs) from other sources, adipose tissue-derived mesenchymal stem cells (ADMSCs) can be isolated easily [10]. ADMSCs have a wide variety of applications, including tissue engineering, regenerative medicine and cell
