A parthenote is an egg that begins dividing as though it were fertilized even though fertilization has not occurred.
Parthenogenesis (Technique C) would be viewed as an affront to human dignity because: (1) of the need to procure oocytes from a healthy female (generally for a price); (2) of the belief that the whole process is "inhuman" due to its asexual nature; and (3) further manipulation of the parthenote might produce an implantable embryo that could become a human being.
Yet the resulting blastocyst, called a parthenote, can be a source of embryonic stem cells.
He is currently working with ISCO's parthenote stem cells to create transplant therapies for the possible treatment of macular degeneration and retinitis pigmentosa (announced March 19, 2007).
ISCO has repeated the experiments using its stem cells derived from unfertilized human eggs, called parthenogenetic human embryonic stem cells (phESC or parthenote stem cells).
Although healthy looking in appearance, both the SCNT embryos and parthenote controls failed to develop into blastocysts, because the wrong culture media were being used.
a scheme utilizing parthenotes and other diploid stocks.
While parthenogenetic mice have been grown to adulthood, (15) it remains unknown whether human parthenotes can develop fully.
Writing for WIRED magazine, Wendy Goldman Rohm witnessed the breakthrough experiment which in pursuit of stem cells yielded both human clone embryos and human parthenotes, embryo-like balls of cells that have only one set of chromosomes.

In our study, the porcine parthenotes and SCNT embryos also developed to the blastocyst stage when cultured in NCSU-23 and mNCSU-23.
