Core Tip

Core Tip: Umbilical cord blood-derived mesenchymal stem cells consist of a unique population of progenitors co-expressing mesenchymal stem cells and neuronal markers capable of instantaneous differentiation. This report is of a 15-year-old male teen with a large patellar cartilage defect due to patellar dislocation who was treated with implantation of human umbilical cord blood-derived mesenchymal stem cells.
