This was Adam Feuerstein tweet (3^rd June16)
“Trading Halt with no explanation. I wonder if it relates to OSIR criminal investigation”.
(ps: This Adam chap has been the subject of his own issues in the past..check google)

However his comment re Osiris is correct - it appears its related to accounting practices and SEC investigation..
..“Osiris Therapeutics Subject of Criminal Investigation;(NASDAQ:OSIR)
by Robin Reyes — May 31, 2016
After six days higher, shares of Osiris Therapeutics (NASDAQ:OSIR) are in the red by as much as 15% after the company confirmed in an SEC filing it is the target of a criminal investigation by the U.S. Attorney’s Office for the Southern District of New York.
The company said it believes the investigation is into the same matters as the SEC Commission’s “non-public investigation” into its accounting practices that was disclosed in March. Additionally Nasdaq has granted the company an extension to file delinquent financial reports until Sept. 12, 2016. The initial filing was delayed as Osiris said it was unable to file its reports while it was completing a review of accounting of revenue recognition practices. Shares last traded at $4.80, near the low of its 52-week range of $3.55 to $23.67.


In regards to the MSC applications that MSB acquired , these are principally
(1) aGVHD application ( pediatric FDA open label 60 patient trial and recently showcased at the Pontifical 2016 stem cell conference by Dr Donna Skerett); and
(2) Cronhs application…based on 9 May 2016 conference call ..back on the agenda a

Furthermore at the time of acquiring these assets in Oct 3013, MSB undertook key due diligence on all a facets of MSC applications, including patents (the professor understands stem cells and how to commercialize same better than anyone in the RM space). So not concerned about the above 2 applications from a science perspective.

From an accounting perspective, IMO not applicable to MSB ( based on patents[assets] due diligence and science in 1 & 2 above going well).

The above are my views only. Please dyor.
