Characteristics of Parthenogenetic Stem Cells and Their Potential Treatment Strategy for Central Nervous System Diseases

Human parthenogenetic stem cells (hpSCs) are a type of human pluripotent stem cell derived from chemically-activated unfertilized oocytes, possessing the ability to proliferate, self-renew, and differentiate into multiple cell types, making them potentially valuable for therapeutic applications. Parthenogenetic stem cells offer an ethical advantage over embryonic stem cells, as they are derived from unfertilized oocytes, avoiding the ethical concerns associated with the use of embryos or fetuses; they also offer a better chance of immune compatibility and lower risk of tumor formation after transplantation. Research suggests that neural stem cells derived from human parthenogenetic embryonic stem cells can express HLA-g and exhibit resistance to natural killer cells, potentially enhancing their survival and integration in cell therapies for nervous system diseases.

• 1
  Parthenogenetic stem cells can differentiate into various cell types, including neural stem cells, mesenchymal stem cells, and cardiomyocytes, suggesting their broad therapeutic potential for regenerative medicine.
• 2
  Studies have shown that parthenogenetic stem cells can differentiate into functional nerve cells in vitro without changing the imprinted state and are more likely to differentiate into neurons and less likely to differentiate into glial cells.

  In animal models of Parkinson's disease and traumatic brain injury, parthenogenetic stem cell-derived cells have demonstrated safety and efficacy in promoting functional recovery, highlighting their potential for treating nervous system injuries.
