They have been using this technology for sometime in racehorses with huge success. They are now in the process of FDA approval to bring it to human trials.
No, its more using the small amount of healthy cells from fragments of healthy adult tissue to repair damaged tissue. Not just horse tendons and ligaments. It depends on what other tissues they are able to successfully apply it to in people or other animals, as well. Not even limiting it to horses. I apologize for not being more clear on that. They got the patent approval for the process. Now they have to get FDA approval to use it. Good process for use now, until the live tissue 3D printing process is refined.
Please read my response to almost the same question. If I rewrote, it may be deleted anyhow for duplicate posting. I apologize for not being very explanatory in my response to Chrion.
