Hydrogel help doctors target tumors in Cancer Treatment

Scientists in Australia created a hydrogel that mimics human tissue, allowing cancer drugs to be tested against tumor samples for efficacy in potential treatment. The 3D-printed gel is is based on collagen and can be used to create microenvironments that, when infused with tumor cells, create models of a patient's cancer, scientists at Queensland University of Technology report in a study.
The gelatin methacryloyl-based hydrogel can be created in one to two weeks and can be modified to mimic the firmness of cartilage or the softness of breast tissue. Once infused with cells from a patient's tumor, the scientists say several drugs can be tested simultaneously.
The scientists said their accomplishment, beyond finding the hydrogel allows for drug testing, is quality control to allow researchers to easily reproduce it.
"Our big breakthrough is we can produce this high-quality material on a very large scale inexpensively," Hutmacher said. "It is highly reproducible which means we have been able to produce this hydrogel hundreds of times, not just once or twice in the lab, so researchers worldwide will be able to create it."

  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.
