Embryology is the study of the development of an embryo. An embryo is defined as any organism in an early stage well before birth or hatching, or in plants, before germination occurs.

Embryos screened to reduce the risk of twins

Japanese researchers say women undergoing fertility treatment may soon be able to have their embryos screened to reduce their chances of giving birth to twins.

Link between ciliary signaling and cancer

Submarines have periscopes. Insects have antennae. And increasingly, biologists are finding that most normal vertebrate cells have cilia, small hair-like structures that protrude like antennae into the surrounding environment to detect signals that control cell growth.

New type of mouse embryonic stem cell discovered

Scientists have discovered a new type of mouse embryonic stem cell that is the closest counterpart yet to human embryonic stem (ES) cells, the National Institutes of Health (NIH) have announced.

Discovery of gene and mechanism essential to the embryonic development of the epididymis

Human sperm cells travel up to 6 meters in their transit from testes to penis, and most of that journey occurs in the epididymis, a tightly coiled tube that primes the cells for their ultimate task: fertilization.

New model for signal transduction in cells

Among the key communication systems within a cell is the Wnt signaling pathway, which regulates embryonic development and whose deregulation can also contribute to cancer development.

New genetic marker characterizes aggressiveness of cancer cells

Levels of a small non-coding RNA molecule called let-7 appear to define different stages of cancer better than some of the "classical" markers for tumor progression, researchers from the University of Chicago report in the June 25, 2007, early online edition of the Proceedings of the National Academy of Sciences.

New way to increase stem cells in blood

Researchers at Children's Hospital Boston report finding a new way to increase stem cells in blood, suggesting a possible treatment to help patients who undergo chemotherapy or bone marrow transplant for leukemia and other cancers recover their immune function more quickly.

60% of people with embryos in U.S. fertility clinics would consider donating them for stem cell research

About 60% of people who have embryos stored at U.S. fertility clinics would be very or somewhat likely to donate them for stem cell research, according to a survey published Thursday in the online edition of the journal Science, Reuters reports (Dunham, Reuters, 6/20).

Novel therapeutic cancer strategy

Cancer sometimes involves processes that should only occur in the embryo being mistakenly reactivated in adult cells.

Embryos that are selected out as abnormal can undergo chromosomal modifications

Ms Tsvia Frumkin, from the Racine IVF unit, LIS Maternity Hospital, Tel Aviv Sourasky Medical Centre, Tel Aviv, Israel, will tell the conference that her team's findings meant that the results of preimplantation genetic screening (PGS) for chromosomal abnormalities were not always reliable and should be interpreted with caution.
