Definition: SpV1-C74 is a type of human embryonic stem cell (hESC) line that has been developed for research purposes, specifically in the area of regenerative medicine and tissue engineering. It is characterized by its ability to differentiate into various types of cells, including hematopoietic stem cells, fibroblasts, adipocytes, and mesenchymal stromal cells. This allows it to be used as a model for studying the effects of embryonic stem cell therapy
