Biomedical research often involves the use of very costly equipment, which have high acquisition and maintenance costs. Examples include MRI (for imaging of the body) and mass spectrometry (for chemical analysis). In the status quo, the vast majority of biomedical research is conducted through "labs" which involve one or two head researchers (often professors), and a team of post-doctoral fellows, masters students, independent researchers, etc. beneath them, all of whom may be working on separate projects. Those labs are housed within institutions (such as universities, hospitals, etc.) which will independently purchase and maintain research equipment. These labs will then work within their institutions to access the necessary equipment (sometimes applying for grants and other funding to support this or to acquire new technology).
