  • Patent number: 11666604
    Abstract: Disclosed are a multilayered cell sheet of cardiac stem cells (CSCs) and a method of manufacturing the same. In particular, the present disclosure provides a method of manufacturing a multilayered cell sheet according to a single step culture procedure by using, as a three-dimensional matrix, a biodegradable natural polymer hydrogel and embedding CSCs in the hydrogel. The multilayered cell sheet of the present disclosure does not require any special device for the manufacturing, is manageable with good physicomechanical property, increases a cell engraftment rate after transplantation based on sufficient accumulation of various growth and protective factors and extracellular matrix between cells, and is also self-assembled by the cell-mediated hydrogel compaction, making nutrients transfer easy. Therefore, the multilayered cell sheet of the CSCs is expected to be usefully applicable as a therapeutic agent for myocardium regeneration.
