Doris Taylor’s research group used detergents to remove all the cells from a cadaveric rat heart, which leaves behind the natural extracellular matrix. An extracellular matrix scaffold can promote the differentiation and rebuilding of a beating heart. The researchers then infused this ECM scaffold with cardiomyocytes. Now these cells differentiated and organized into a functionally contracting “recellularized” heart. Which of the following statement is correct?
