In my 20 mins of searching; it looks like it's CCN3 is produced by humans (https://en.wikipedia.org/wiki/NOV_(gene)) and presumably humans have the receptors for it as well - though I'm uncertain if the same effect in mice will translate to humans. Since naturally occurring genes and genetic sequences are not patentable even if they don't commercialize you could probably get a 3rd party to make it reasonably cheaply. So if it is found to work I wouldn't even worry about commercialization.
