Stem cells in bone marrow replenish mouse ovaries

... marrow and blood of mice can "restock" a depleted ovary with new egg cells within weeks, according to new ...certain hormones. Further results suggest that the ovary itself is sending out a chemical signal to the bone marrow, readying the progenitor cells to travel ...

By creating molecular bridge, scientists change function of a protein

...hormone receptor mostly expressed in the prostate, ovary and urinary tract. What they did was modify the estrogen receptor in a step-wise fashion, Zhao said. They used testosterone and progesterone to build the bridge. The receptor was gradually altered to accept one steroid, then another, until accepting...

New Discovery May Help Doctors Treat Infertility

...eceptor plays a role in moving the egg outside the ovary so it can be fertilized,?said Kenneth Korach, Ph.D., Laboratory Chief at the National Institute of Environmental Health Sciences (NIEHS) where the research was conducted. “We never knew before what function this receptor played in reproduction.?/p...

ASU researchers find link between social behavior, maternal traits in bees

...iffer between the two strains also correlated with ovary size in the experiment. The success of Amdam's research could prove more far-reaching than just the evolution of bee social behavior--scientists can use the findings as a stepping stone when looking at the social evolution of other animals. "Our fi...

New weapon in battle against osteoporosis

...y we were able to diminish the bone loss caused by ovary removal," explains the molecular biologist. Many patients carry a particular variant of the CB2 gene But how far can these results be applied to human beings? To answer this question, Dr. Karsak turned to a team of scientists working in France ...

Researchers identify genes in fruitflies that may shed light on human cancer spread

...urned on in so-called border cells of the fruitfly ovary that migrate during normal development. Two main t...." Although border cell migration in the fruitfly ovary may seem a far stretch for studying human cancer metastasis, the genes uncovered in this study share...

One-third of adults with diabetes still don't know they have it

...baby weighing more than 9 pounds have polycystic ovary syndrome, a metabolic disorder that affects the female reproductive system have acanthosis nigricans (dark, thickened skin around neck or armpits) have a history of disease of the blood vessels to the heart, brain, or legs have had IFG or IGT on...

Study finds how organs monitor themselves during early development

Even when faint, ovary scent draws sperm cells

...m cells to follow the weakest of scents. Even when ovary extracts were diluted 100,000 times, some sperm cells still found their mark.

New technology addresses female fertility preservation

...ervation of fertility." The technology mimics the ovary and its environment. Follicles (each follicle has one egg) from mice were grown in vitro until fully matured by providing the follicles and eggs with the necessary hormones for development while maintaining their normal architecture. The eggs were th...

Major cancer study aims to identify protein markers for early-stage disease

...ntigen 125 (CA-125) suggest possible cancer of the ovary or other organs. However, both tests have "false negatives" or "false positives," making them unreliable. If mass spectrometry can be refined and standardized, scientists say, it could revolutionize the detection of cancer and lead to earlier interv...

Researchers discover that sheep need retroviruses for reproduction

...e retroviruses infected the germline (cells of the ovary and testis that have genetic material that are passed to their offspring) of the host, which is then inherited by their children. These retroviruses, known as endogenous retroviruses, are present in the genome of all mammals, including humans. Cons...

The power of one: A simpler, cheaper method for cell fusion
