3D bioprinting could make cancer treatments more effective

Cancer is one of the leading causes of death worldwide. In fact, according to the World Health Organization (WHO) data, only in 2020 years, cancer will cause approximately 1,000 Thousands of people died, almost every 6 There are people 1 People die of cancer. However, even though research into treatments continues, there is still a long way to go before we find a cure. Maybe there will be new hope. Korea Machinery and Materials Research Institute (Korea Machinery and Materials Institute) under the Ministry of Science and Information and Communications Technology of South KoreaKim) and the Korea Institute of Bioscience and Biotechnology (CRAB) scientists announced a new3DBioprinting technology, which they say could become a new way to treat cancer, particularly solid tumors.

Solid tumors are defined as tumors having a solid body and a shape composed of blood vessels and connective tissue. Solid tissues are difficult to treat, particularly with immunotherapy. This therapy uses substances to strengthen the immune system, particularly natural killer cells (N.K. cells), a type of white blood cell that kills cells that are harmful to the body. The cancer center says immunotherapy is often recommended for patients with advanced cancer and is very effective in treating certain types of cancer. This is the result of the latest research.

Basically, in immunotherapy,N.K. The cells were injected intravenously. However, in this new approach,3DHydrogel printing will allowN.K.The cells are enveloped. This helps prevent N.K. The loss of cells allows more cells to focus on the tumor cells themselves. This is achieved through the gradual formation of pores in a hydrogel composed of sodium alginate and gelatin, such thatN.K.The cells can be released later. Furthermore, due to N.K. The cells were injected into the hydrogel, printed and cultured, and their cell viability and activity were improved.

So far, the research is promising. The research paper states that hydrogels are N.K. The cells create an appropriate environment that allows N.K. cellular 3D Bioprinting is emerging as a viable potential therapy and paves the way for more effective cancer treatments. Since Kim principal investigator Su A Park The summary says:“This technology could help significantly improve the effectiveness of cancer treatments N.K. Cellular functions. We hope to use this newly developed technology to help treat cancer patients. You can download the full research report here.
