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.
Human adult stem cells are being used to cure cirrhosis and other serious live diseases. Another 15 people in Brazil on the liver transplant waiting list have been treated by cellular therapy with encouraging results. “We are still in a strictly experimental phase” underlined Luiz Guilherme Costa Lyra, hepatologist and coordinator of the study performed by Sao Rafael di Salvador Hospital, collaborating with San Raffaele Hospital of Milan. “We must clarify that this therapy is not available for any patient outside of the experiment, so it is useless for anyone to write us asking to get
In what could be a major breakthrough in fighting prostate cancer, a researcher from Gitam Institute of Technology (GIT) has found that a drug used for treating coronary heart disease and stroke can control the progression of this form of cancer.
Prostate cancer develops in the prostate, a gland in the male reproductive system, and is said to be among the top three types of cancers afflicting men apart from lung and gastric cancers. Patients suffering from prostate cancer have difficulty in urinating, feel the need to frequently pass urine and experience pain when passing urine.

Using skin cells from people with type 1 diabetes, researchers were able to produce cells that made insulin in response to changing blood sugar levels, though not as efficiently as normal insulin-producing cells do. (…) “This is a big deal,” said Susan Solomon, CEO of the New York Stem Cell Foundation, which provided some of the funding for the study. “Tackling the basic biology of type 1 diabetes, which is a very complex disease, is a critical step. With these cells, we can see in a dish what’s happening to the immune system, and if
While looking for mechanisms that might be relevant to restoring regenerative potential in older skeletal muscle, HSCI Executive Committee member, Amy Wagers, PhD, and her team, thought about mechanisms that had been studied for a long time evolutionarily as regulating lifespan and longevity. One example of such a mechanism is reduced calorie intake in the absence of malnutrition, also know as calorie restriction, which has been show to extend lifespan in many organisms.
In order to address the question of whether calorie restriction could also affect skeletal muscle regeneration, Wagers and her colleagues placed mice for 12 weeks
