Abstract
Provided are compositions and methods that relate ex vivo organoids that contain B cells and stromal cells in a three dimensional material includes a hydrogel. The hydrogel can be formed without exposure to ultraviolet light from an electronic ultraviolet light source. The hydrogel contains silicate nanoparticles (SiNPs) that are ionically bonded to a polyampholytic gelatin. The three dimensional material can be held at a temperature of at least 37 degrees Celsius and does not liquefy. The organoids exhibit mechanical properties that are similar to certain lymphoid tissues, and can include a germinal center. Methods of making the organoids are included, as are high throughput screening approaches that use the organoids for screening a variety of test agents. The organoids can synthesize a variety of compounds that can be recovered from the organoids or the organoid culture medium.
