Model of tumor spreading helps doctors pick best Cancer treatment

The idea behind a new invention by scientists at Wake Forest Baptist Medical Center's Institute for Regenerative Medicine. In the journal Biotechnology and Bioengineering, the team reports on its "metastasis-on-a-chip" system believed to be one of the first laboratory models of cancer spreading from one 3D tissue to another.
The research team is working to further develop the system in hopes that it can one day be used to quickly reveal the best way to treat an individual patient's cancer.
"We believe the metastasis-on-a-chip system has potential for making meaningful advances in cancer investigation and drug discovery," said Aleks Skardal, Ph.D., lead author and an assistant professor of regenerative medicine.
This is a relatively new focus of cancer research. For example, the scientists learned that a "stiffer" tumor was more apt to metastasize, suggesting the possibility of using drugs to alter the mechanical properties of a tumor to reduce its likelihood of spreading.
The system has the potential to address some of the shortcomings of current research methods. For example, the results from traditional 2D studies in laboratory dishes as well as studies in animals often are not applicable to human patients. Often, seemingly promising drug candidates may fail when they reach studies in humans.

  1. I'm 55-year-old from Korean, I was diagnosed with second-stage liver cancer following a scheduled examination to monitor liver cirrhosis. I had lost a lot of weight. A CT scan revealed three tumors; one in the center of my liver in damaged tissue and two in healthy portions of my liver. No chemotherapy or radiotherapy treatment was prescribed due to my age, the number of liver tumors. One month following my diagnosis I began taking 12 (350 point) Salvestrol supplements per day, commensurate with my body weight. This comprised six Salvestrol Shield (350 point) capsules and six Salvestrol Gold (350 point) capsules, spread through the day by taking two of each capsule after each main meal. This level of Salvestrol supplementation (4,000 points per day) was maintained for four months. In addition, I began a program of breathing exercises, chi exercises, meditation, stretching and stress avoidance. Due to the variety of conditions that I suffered from, I received ongoing medical examinations. Eleven months after commencing Salvestrol supplementation But all invalid so I keep searching for a herbal cure online that how I came across a testimony appreciating Dr Itua on how he cured her HIV/Herpes, I contacted him through email he listed above, Dr Itua sent me his herbal medicine for cancer to drink for two weeks to cure I paid him for the delivering then I received my herbal medicine and drank it for two weeks and I was cured until now I'm all clear of cancer, I will advise you to contact Dr Itua Herbal Center On Email...drituaherbalcenter@gmail.com.
