- Mouse model advances understanding of synovial sarcoma
04-09-2007 · EurekAlert!
A mouse model for synovial sarcoma has enabled scientists to make tremendous progress toward understanding the origin and pathogenesis of this highly aggressive soft-tissue malignancy. The research, published in the April issue of the journal Cancer Cell, published by Cell Press, provides new information about the timing and environment required for initiation and progression of synovial sarcoma. The mouse model is also likely to serve as an invaluable resource for development of successful therapeutic strategies for this often lethal cancer.

- Cell growth technology promises more successful drug development
09-18-2007 · EurekAlert!
Scientists have developed unique technology to grow stem cells and other tissue in the laboratory in conditions similar to the way they grow in the human body. The technology, developed and patented by scientists at Durham University, UK, and its spin-out company ReInnervate Limited, is a plastic scaffold which allows cells to be grown in a more realistic three-dimensional form compared to the traditional flat surface of a Petri dish.

- Progress toward an alternative for EPO: Gas6 offers remedy where EPO fails today
01-31-2008 · EurekAlert!
Many patients with a chronic disease or cancer have to contend with anemia. At present, the hormone EPO is administered to a large number of these patients to alleviate the anemia. But unfortunately, treatment with EPO is not always effective. VIB scientists have been researching the role of the Gas6 protein. This substance has proven successful in the treatment of mice with anemia. In addition, Gas6 contributes to a reinforcement of EPO's effect.

- Scientists discover how to isolate stem cells in womb tissue
09-12-2007 · EurekAlert!
Scientists in Australia have found a way of identifying probable stem cells in the lining of women's wombs. The finding, published in the journal Human Reproduction, opens up the possibility of using the stem cells for tissue engineering applications such as building up natural tissue to repair prolapsed pelvic floors.

- Paracetamol, one of most used analgesics, could slow down bone growth
09-03-2007 · EurekAlert!
UGR scientists stress the need for controlling the use of paracetamol, as it has been proved "in vitro" that it slows down bone regeneration. Their work has demonstrated that applying plasma rich in growth factors, from the patients themselves and applied on the bones, accelerates cell growth. Therefore, it could also be used to regenerate wounds or ulcers when applied over soft tissue. Results of this research have been published in prestigious journals such as Bioscience Reports, Oral Diseases and Physiology and Biochemistry among others.

- First case of successful ovarian tissue transplantation between two, nonidentical sisters
08-01-2007 · EurekAlert!
A woman, whose ovaries had failed due to damage caused by chemotherapy and radiotherapy, has received a successful ovarian transplant from her genetically nonidentical sister. The transplant restored her ovarian function, she started to menstruate and, after a year, doctors were able to recover two mature oocytes from her ovaries and fertilize them to produce two embryos. The case is reported in the journal Human Reproduction.
