It allows you to increase the effectiveness of the fight of immune cells with large solid tumors.
Korean engineers from the Korea Machinery and Materials Institute and the Biological Sciences and Biotechnology Research Institute have created a method of oncological immunotherapy based on three-dimensional bioprinting.
They used live NK (natural killer) cells encapsulated in a hydrogel to increase their viability, tumor delivery, and effectiveness in fighting cancer cells.
By 3D printing incorporating micro-macroporous gelatin and sodium alginate hydrogels and NK cells, they developed artificial 3D structures that function like natural tissues and organs.
Note that the current method of cancer treatment using NK cells by intravenous injection is not always effective. Especially against large solid tumors. All due to rapid loss of cell viability.
A new method using 3D printing overcomes these hurdles.
