Research clarifies origin of mammalian network of lymphatic vessels

Investigators at St. Jude Children's Research Hospital settled a century-old debate on the origin of the mammalian lymphatic vasculature - the network of vessels and capillaries critical to various essential housekeeping functions in the body.

New egg-specific gene, JY-1 offers clues to infertility

A newly identified gene that controls embryo development in cows may someday offer clues into the cause of infertility in women.

Decoding effects of toxins on embryo development

Changes in gene expression patterns in zebrafish embryos resulting from exposure to environmental toxins can identify the individual toxins at work, according to research published in the online open access journal Genome Biology.

Advances in drug screening

With the discovery of suitable molecular targets - cellular molecules along pathways crucial for sustaining the life of cancer cells - comes the perplexing dilemma of where to find the next therapeutics that will bind to and disable those targets.

Experts warn women about experimental fertility options

The American Society for Reproductive Medicine (ASRM) has warned women that two experimental fertility procedures currently being offered remain unproven.

New stem cells by reprogramming

Researchers are discovering new ways to help ‘de-program' specialised cells so that they can be re-programmed to form a range of different types of tissue, an international meeting of stem cell biologists was told.

Sex hormone signature indicates gender rather than just chromosomes

Help with assigning gender could one day be at hand for intersex individuals whose genital phenotypes and sex chromosomes don't match, thanks to the discovery of a stable sex hormone signature in our cells.

In-vitro fertilization improved with 3-D/4-D-guided embryo transfer and new placement target

The pregnancy rate for patients undergoing in-vitro fertilization (IVF) is improved when doctors use advanced 3D/4D imaging to guide the placement of embryos to the point where the endometrium is most receptive to implantation, according to a study presented at the 63rd Annual Meeting of the American Society for Reproductive Medicine (ASRM).

Sex once a day... on doctors orders!

The latest research into male fertility has the news all men want to hear - the more sex a man has the more fertile he becomes - at least in some cases!

Researchers working on the development of drugs to limit neuronal death

Neurons die en masse when the spinal cord is injured or when a person suffers a stroke. Researchers of the Max Delbrueck Center for Molecular Medicine (MDC) Berlin-Buch, Germany, and of Aarhus University, Denmark, have unraveled the molecular mechanism which causes the death not only of damaged neurons, but also of healthy nerve cells.

Important insights into blood vessel formation

Researchers have identified a molecular pathway that plays a critical role in the growth of blood vessels.

Scientists answer century-old developmental question

Embryologists at UCL (University College London) have helped solve an evolutionary riddle that has been puzzling scientists for over a century.

Research shows how stem cells decide to become either skeletal or smooth muscle

Researchers have discovered a key protein that controls how stem cells "choose" to become either skeletal muscle cells that move limbs, or smooth muscle cells that support blood vessels, according to a study published in the Proceedings of the National Academy of Sciences (PNAS).

Adult stem cells lack key pluripotency regulator

The protein Oct4 plays a major role in embryonic stem cells, acting as a master regulator of the genes that keep the cells in an undifferentiated state.

Link between woman's hips and daughter's risk of breast cancer

In a study of the maternity records of more than 6,000 women, David J.P. Barker, M.D., Ph.D., and Kent Thornburg, Ph.D., of Oregon Health & Science University discovered a strong correlation between the size and shape of a woman's hips and her daughter's risk of breast cancer.
