TaiGen Biotechnology Co., Ltd. announced today that in a phase 1 study in healthy volunteers TG-0054, a chemokine receptor CXCR4 antagonist, was well tolerated and rapidly mobilized stem cells and endothelial progenitor cells from bone marrow into peripheral blood. The number of CD34+ stem cells in circulation after one dose of TG-0054 was equal or higher than reported cell numbers needed for stem cell transplantation in cancer patients. The observed AEs were all mild and transient. A phase 2 study in stem cell transplantation for multiple myeloma, non-Hodgkin lymphoma and Hodgkin disease patients is currently being initiated (…)
An experimental drug is on the way, which might be effective to fight brain cancer (glioblastoma) and prostate cancer.
The researchers are experimenting on this drug at the University of Texas Southwestern Medical Centre (UTSMC).
According to Jerry Shay, professor of cell biology, the drugs are promisisng because they attack not only the tumour cells but also the rare cancer stem cells in the body. So, it would be effective to root out cancer from the body.
“Because it attacks a mechanism that’s active in most cancers, it might prove to be widely useful, especially when combined with other therapies,” said Shay.
The team at Children’s Hospital Boston and the Harvard Stem Cell Institute were working with a new type of cell called induced pluripotent stem cells or iPS cells, which closely resemble embryonic stem cells but are made from ordinary skin cells.
In this case, they wanted to study a rare, inherited premature aging disorder called dyskeratosis congenita. The blood marrow disorder resembles the better-known aging disease progeria and causes premature graying, warped fingernails and other symptoms as well as a high risk of cancer.
One of the benefits of stem cells and iPS cells is that researchers can make them from
BRITISH face surgeons are to grow new skull, cheek and jaw bones on patients’ backs using their own stem cells.
The surgeons, from Barts and the London NHS Trust, hope to use the technique to help people whose facial bones have been destroyed by cancer or injury.
Four patients are awaiting the treatment, which the surgeons believe could eventually become a less risky alternative to face transplants. Two are cancer victims and two have had accidents.
The team, led by Iain Hutchison, will make the first attempt to grow replacement bone from a patient’s own stem cells in Britain.
The procedure involves constructing

Hong Kong scientists say they have identified the cancer stem cells responsible for the spread of colorectal cancer to other organs and believe the find will revolutionise treatment.
Current treatments regard all cancer cells as alike, but the Hong Kong University researchers discovered that cancers contain a small number of stem cells responsible for starting and maintaining tumours.
“It will revolutionise the approach to cancer treatment in future,” one researcher, Ronnie Poon, told the South China Morning Post.
