My guess is that a university (or more) might be involved. Perhaps some private entities too?
As part of research, many university professors/scientists take part in such things and work with private companies. They apply for federal grants that can be used for such liaison and research. Also, some professors/scientists might not be tenured yet and this kind of research looks great towards that end. Those that are tenured eat this kind of thing up too. Imagine the possibilities for BIEL if such research validates use of the product for other indications outside of musculoskeletal.
The conjoint effort provides great prestige to the research teams, individuals, the university, and brings in even more grant monies given successful outcomes. The added advantage is that many universities are politically connected and work with people of influence. That kind of networking can open many doors. The old saying of it's not just what you know, it's who you know, that rings true.
Yes, BIEL deserves serious attention.
