Scientists Find Breakthrough Use of Light to Kill Cancer Cells
In a world-first, scientists have developed a breakthrough treatment that uses light to kill cancer cells.
We often think of light as a life-giving source, but in the case of photoimmunotherapy — the use of light to help a person’s own immune system fight cancer — light can both be a source of life, for the patient, and death, to cancer cells.
A multidisciplinary team of European scientists joined forces to design the new treatment, which works by combining a special fluorescent dye with a cancer-targeting compound.
Shining light on the compound forces cancer cells to glow in the dark, helping surgeons to remove more of the tumors compared with existing techniques.
Then, the surgeon would shine near-infrared light on the site, switching the compound into tumor-killing mode and killing off any remaining cells.
The trial of this therapy was done on mice with a particularly aggressive form of brain cancer called glioblastoma.
Findings showed that the mice had clear signs of tumor death in as little as one hour after exposure to the light. The treatment also triggered an immune response that could mount a new attack on cancer should it come back.
Study leader Dr. Gabriella Kramer-Marek told The Guardian, “Brain cancers like glioblastoma can be hard to treat, and sadly, there are too few treatment options for patients. Surgery is challenging due to the location of the tumors, and so new ways to see tumor cells to be removed during surgery and to treat residual cancer cells that remain afterward could be of great benefit.”
Scientists are quite hopeful that the results will be duplicated when they study the treatment of humans. In the meantime, this trial has shined a light at the end of a long, dark tunnel.
Stem Cells From One's Own Body Show Efficacy in Treating Pain
Stem cell therapy is still a relatively new concept that few understand, but it continues to garner a lot of support and promise — especially for medical problems that have traditionally been very difficult to treat. In his fascinating discussion with Open Minds host Regina Meredith, naturopathic doctor Harry Adelson N.D. reveals a new way to address pain by using stem cells as curative agents. This may come as a welcome idea for at least a fifth of the population, who suffer from chronic pain that affects quality of life, the ability to work, sleep patterns, and more.
According to the Mayo Clinic stem cells create other cells with specialized functions, and “[u]nder the right conditions in the body or a laboratory, stem cells divide to form more cells called daughter cells. These daughter cells either become new stem cells (self-renewal) or become specialized cells (differentiation) with a more specific function, such as blood cells, brain cells, heart muscle cells or bone cells. No other cell in the body has the natural ability to generate new cell types.”
Adelson, says treatment with stem cells can help treat musculoskeletal pain and increase energy using cells from one’s own bone marrow and fat to prompt regeneration. Citing his own use of stem cells on his road to recovery from injury and pain, Adelson says how regenerative therapy using biological tissues found in the human body can restore normalcy to someone living with pain and suffering.
One of the more exciting aspects of stem cell therapy is that each of us can create our own cells to heal ourselves. Emerging evidence suggests that adult stem cells can not only replicate, but also create various other types of cells. For example, bone marrow stem cells may be able to create bone or heart muscle cells.
Adelson is highly experienced when it comes to using stem cells for pain treatment, having performed numerous procedures using bone marrow combined with adipose (bodily fat) stem cells. He’s also injected more than a thousand intervertebral discs with stem cells.
Adelson’s excitement for stem cell therapy began with an accident as a young man, while rock climbing in the early 1990s. He was in naturopathic school at the time, when an injury to his shoulder set him off in a new direction, leading him to pursue an alternative to traditional surgery and injections for pain treatment. After receiving his naturopathic degree, Adelson discovered the potential of stem cell therapy.
