Cytomegalovirus (CMV) is more common in semen than generally thought, according to a new study by Bedford Research Foundation scientists.
CMV is a common herpes virus that causes a minor disease in children and adults, but can also infect fetuses in utero and causes permanent problems in 1 out of 750 children born in the U.S.
In the February issue of Fertility and Sterility, the official journal of the American Society for Reproductive Medicine (ASRM), Bedford Research scientists report two surprising findings: First, nearly half (45%) of the semen specimens from 68 men without and with HIV co-infection had detectable CMV, including specimens from two men who initially tested negative for antibody against CMV in their blood. Second, men with even mild suppression of their immune system were twice as likely (57%) to have CMV in their semen as men with normal immunity (28%).
Dr. Ann Kiessling to give 2014 OSU commencement address in Reser Stadium
Excerpt from The Oregonian: Stem cell pioneer picked as
Ann Kiessling, who earned a doctorate in biochemistry and biophysics from OSU in 1971 and now directs the Bedford Stem Cell Research Foundation, will address the Class of 2014 at graduation ceremonies in Reser Stadium.
A native of Baker City, Kiessling taught at Oregon Health & Science University from 1977 to 1985 and helped launch Oregon’s first research lab in human in vitro fertilization. In 1985 she joined the faculty at Harvard University, where she specialized in obstetrics, gynecology and reproductive biology and developed reproductive options for couples with HIV and hepatitis C.
She is also a leader in the therapeutic use of stem cells, authoring the first textbook on the subject in 2003. Since 2011 she has pursued her scientific interests at the Bedford Stem Cell Research Foundation, a private research institution in Massachusetts.

Join us in person or watch it live online! Dr. Mario Capecchi will keynote the tenth annual Symposium. Dr. Capecchi is a Distinguished Professor of Human Genetics & Biology at the University of Utah School of Medicine, an Investigator with the Howard Hughes Medical Institute, as well as a 2007 Nobel Laureate for Physiology & Medicine.
Stem cell-based treatments, termed regenerative medicine, are being developed to replace defective tissues and organs such as heart and kidney failure, spinal cord injury and disease, diabetes, AIDS, Parkinson’s and Alzheimer’s diseases, and degenerative joints. The source of the stem cells is key. If they can be harvested from the patient, there will be no problems with tissue rejection, such as can happen with kidney or heart or bone marrow transplants from donors. SCNT provides a powerful method to create stem cells with the patient’s own chromosomes, thus a perfect tissue match. SCNT had been accomplished in many species, but not human.
In the course of trying to understand how cells became committed to each tissue and organ in the body, scientists discovered that if the chromosomes were removed from an egg, and replaced with the chromosomes (in the nucleus) of an adult cell, it was possible to stimulate the egg to begin to divide into multiple cells just as if it had been fertilized with sperm. Thus, nuclear transplantation refers to the process of replacing egg chromosomes with the chromosomes of another cell, usually a cell that has been growing in the laboratory. This research success made it possible to try to clone adult animals. It is important to note that the success rate in cloning animals is very low, fewer than 1% of eggs that undergo nuclear transplantation, but the success rate in stimulating the transplanted egg into dividing into multiple cells is high. Thus, such transplanted eggs may be ideal candidates for stem cells, but not for producing clones. Read more in our FAQ

The current raucous debate over the commonly used PSA blood test to screen for prostate cancer, the third leading cause of cancer deaths in men in the U.S.(a), stems from the U.S. Preventive Services Task Force’s recommendation to discontinue PSA screening(b). The debate is pitting physician against physician, cancer advocacy groups against health care insurance companies, and leaving men with enormous questions about what to do about their lifetime risk of developing prostate cancer.
The Task Force’s recommendation is based on it’s review of medical literature that concluded that PSA screening leads to more unnecessary treatment complications than are justified by lives saved because... Read More
A recent article in Scientific American questioned whether research on stem cell lines derived from unfertilized eggs was too tightly regulated by the federal government. Now that technology allows the creation of stem cells without fertilization, there is no question that federal laws and guidelines are overly restrictive, causing a detrimental effect on valuable scientific inquiry.
Since 1996, Congress has included the Dickey-Wicker Amendment in the annual federal budget. This amendment was a conservative reaction to what some considered to be scientific research that showed little respect toward life.... Read More
My support for stem cell research has its foundation in my deep-seeded belief in reproductive rights for women. Since I came of age in the 1970’s, women’s reproductive rights and freedom have been continually eroded by federal and state legislation. That has been coupled with diminished government support and funding – ranging from access to abortion services to stem cell research. Because of that, I have volunteered time and donated money to help preserve these rights.
But last summer, my support for stem cell research became personal. During a mugging on the Cape, my stepson was shot by the assailant, resulting in a severed spinal cord at T-5. He’s now a parapalegic... Read More
BSCRF scientists have derived two unique lines of stem cells that may lead to a breakthrough in the efficiency of stem cell derivation and expansion.
BSCRF scientists are following up their discovery that the genes that regulate the rhythms of daily life, circadian rhythm genes, may play important roles in stem cell derivation and stability in culture. Circadian rhythm genes regulate cells in the body by turning “on” and “off” over a 24-hour cycle in response to signals such as light/dark cycles, hormone pulses, and body temperature variations.
