Better understanding of membrane fusion

Cells constantly swap cargo bound in vesicles, miniscule membrane-enclosed packages of proteins and other chemicals. Before the swap can take place, the vesicle membrane must fuse with another membrane, creating channels packages can pass through.

Connection between cancer development and Darwinian evolution explored

Cancer is a natural consequence of human evolution. Our genes have not developed to give us long and happy lives.

Scientists discover key player in embryonic muscle development

Muscle fibers are large cells that contain many nuclei. They begin, like all animal cells, as naive embryonic cells. These cells differentiate, producing intermediate cells called myoblasts that are now destined to become muscle.

Boston IVF announces participant in fully enrolled egg freezing study has become pregnant

This is the first pregnancy in Massachusetts to result from egg freezing. The study was performed by Boston IVF and sponsored by an independent medical grant from EMD Serono, a biotech company with an area of focus on infertility.

California Senate Committee approves bill that would allow HIV-positive men to have sperm washed

The California Senate Health Committee on Wednesday voted unanimously to approve a bill (SB 443) that would allow HIV-positive men to have their sperm washed and used for fertility treatments, including artificial insemination and in vitro fertilization, under certain guidelines, the San Francisco Chronicle reports.

Multiple malaria infection inhibits spread of parasite

People who are frequently infected with malaria parasites can develop immunity against the gametocyte, the infectious stage. This immunity inhibits the spread of the parasite. Dutch researcher Mike van der Kolk discovered this during his research into malaria transmission under the inhabitants of Cameroon, Senegal and Indonesia.

New procedure to estimate reproductive potential of individual embryos

To address the high rate of multiple births resulting from in-vitro-fertilization (IVF), researchers at Yale School of Medicine and McGill University have developed a procedure that estimates the reproductive potential of individual embryos, possibly leading to a decrease in multiple-infant births and a higher success rate in women undergoing IVF.

Ultrasound could help couples undergoing IVF

Ultrasound-based tests allowing women undergoing in-vitro fertilization (IVF) to count their chickens before they've hatched may provide alternatives to the hormone-based tests used today.

California Sen. Carole Migden introduces bill to allow HIV-positive men to use reproductive services

California Sen. Carole Migden (D) recently introduced a bill (SB 443) that would allow HIV-positive men to use reproductive services, including artificial insemination and in vitro fertilization, under certain guidelines, the MediaNews/San Jose Mercury News reports.

Steroid use fails to boost pregnancy rates in infertility treatments

There is no clear benefit from a hormone commonly prescribed to enhance the effectiveness of infertility treatments, according to a new review of studies.

MIT researchers develop technique to encourage the survival and growth of adult stem cells

Adult stem cells, found in many tissues in the body, are precursor cells for specific cell types. For example, stem cells found in the bone marrow develop into blood cells, bone cells and other connective tissues, and neural stem cells develop into brain tissue.

U.K. Human Fertilisation and Embryology Authority approves compensation for eggs donated for research

The United Kingdom's Human Fertilisation and Embryology Authority on Wednesday approved a policy that will allow women who donate eggs for human embryonic stem cell research to receive up to $500 for each cycle to cover costs associated with travel and lost wages, the AP/Washington Post reports

Increased demand, compensation for egg donors in U.S.

The AP/Boston Globe on Monday examined how increased demand for egg donations and compensation for donors in the U.S. has prompted more young women to donate their eggs. According CDC data, about 10,000 women donated eggs to federally monitored programs in 2004, compared with 3,800 women in 1996.

Researchers replace organ in mice using 'single-parent' stem cells

Researchers at the University of Pennsylvania School of Veterinary Medicine have derived uniparental embryonic stem cells - created from a single donor's eggs or two sperm - and, for the first time, successfully used them to repopulate a damaged organ with healthy cells in adult mice.

Women who donate eggs for stem cell research face few health risks

Women who donate their eggs for stem cell research or in vitro fertilization are not at increased risk of health complications, and most of the risks are a result of the hormones used to stimulate their bodies to release more than one egg, according to a report commissioned by the California Institute of Regenerative Medicine and released by the Institute of Medicine, Bloomberg reports.
