Parthenogenetic Stem Cells

Parthenogenetic stem cells are created from unfertilised eggs using parthenogenesis. They were first created, unintentionally, by South Korean scientist Hwang Woo-Suk, who along with his team developed the first human embryos resulting from parthenogenesis. Their "discovery" occurred sometime in 2004, but remained unknown until August, 2007 when independent investigation pointed it out.

The first intentional creation of parthenogenetic stem cells was announced on June 26, 2007 by  researchers from the International Stem Cell Corporation (ISCC), a biomedical stem cell research company based in California.  The research team was led by Dr. Elena Revazova.

According to ISCC, human parthenogenetic stem cells have the following advantages:
  • Have similar properties to embryonic stem cells, being pluripotent in nature
  • They cause smaller, if any, rejection reactions, when compared to other types of stem cells
  • Their use isn't debatable as they are extracted from unfertilised eggs (thus no embryo is destroyed)

ISCC has already announced some positive preclinical results including:
In a 2013 study, Wolfram Zimmerman and his team showed that parthenogenetic stem cells can be used to treat heart failure
