Consistently, ectopic expression of a Notch target, Hindsight (Hnt) (Yip et al., 1997; Krejci et al., 2009), is sufficient to halt cell division and induce the endocycle (Sun and Deng, 2007), thereby generating egg chambers containing reduced number of follicle cells with larger nuclei.
The technique has been used to generate eggs in animals, but it has not yet led to a successful pregnancy.
Breeding, too, is another Pokemon series staple, which makes sense as a more targeted way to generate Eggs for players to hatch.
The findings are already inflaming the debate over when and how female mammals generate eggs; if confirmed, they could offer hope of new options to treat human infertility.
They also want to generate eggs in vitro, both to understand the process and to ultimately try to help infertile women.
For example, the adjoining illustration shows the life cycle of the intestinal fluke metagonimus, which hatches in the intestine of a snail; moves to a fish, where it penetrates the body and encysts in the flesh; then moves to the small intestine of a land animal that eats the fish raw; and then generates eggs that are excreted and ingested by snails, thereby completing the cycle.
All alleles generate eggs with fused appendages, indicative of reduced Grk signaling, although levels and localization of grk mRNA appear normal.
Women in this situation, however, may be able to benefit from the capacity to generate eggs in vitro from other types of cells, either embryonic stem cells (ES cells) or induced pluripotent stem cells (iPS cells).
Page A7 National STUDY FINDS STEM CELLS CAN CREATE HUMAN EGGS Researchers at Massachusetts General Hospital say they have extracted stem cells from human ovaries and made them generate egg cells.
