ISCO's core technology, parthenogenesis, results in the creation of pluripotent human stem cells from unfertilized oocytes (eggs).
Some scientists reported that this mealybugs was bisexual reproduction (Hodgson et al., 2008; Aheer et al., 2009; Prasad et al., 2012; Huang et al., 2013) whereas, some other scientists reported that parthenogenesis with ovoviviparity was dominant over the oviparous mode of reproduction (Nikam et al., 2010; Kumar et al., 2010; Vennila et al., 2010).
The researchers reasoned that if they could turn the gene on in an egg cell, they might be able to bypass the fertilisation step, triggering embryo growth without sperm, a process called parthenogenesis, according to the lead author of the paper.
In addition, parthenogenesis has been suspected on the basis of the scarcity of males in some other Elaphoidella species: E.
Parthenogenesis, Greek for a virgin birth (literally "virgin creation," not applicable to religious figures like Jesus of Nazareth), has been around among different species in nature for over hundreds of thousands of years, and has long been known about in science.
