While it doesn't represent lock-tight connection about the specifics of a relationship between AMBS(MANF) and Banyan(who given that their website's "latest news" is from 2012 seems rather pathetic about keeping a stream of up-to-date developments) there certainly is enough reason to strongly speculate,
"The data shows that MANF has a significant ability to reduce cell death from a variety of insults that simulate Traumatic Brain Injury as we have modeled in multiple assays in our internal laboratories at Banyan," said Dr. Andreas Jeromin, PhD, Senior Director Research at Banyan, "These data give us confidence to move to the next phase of testing to further validate this approach, as well as look at innovative product development strategies to accelerate bringing a MANF-based treatment to patients for TBI." http://www.prnewswire.com/news-releases/amarantus-biosciences-and-banyan-biomarkers-announce-positive-data-from-traumatic-brain-injury-collaboration-157732095.html
Also given that these Banyan statements were been made within the time periods that we do know Banyan has been working with DOD on TBI including a verified study involving human patients.
