I went ahead and read through everything on the Osiris Therapeutics site that bluerider2 linked to earlier. Regarding the Chron treatment specifically—which is what I'm really looking into—it’s currently only been tested on about ten patients, but they've seen some pretty significant progress after just two rounds of therapy, which seems quite promising. From what I can gather, it's moving into phase three of the clinical trials right now, and they're actually accepting applications for people who want to participate in the study. This initial testing period lasted about 28 weeks, and even within that relatively short window of monitoring the patients, the results were impressive. They measure the stage of Chron using certain indices, and according to those metrics, the outcomes have been very strong. So, we're seeing real improvement in a very short amount of time. Now that they're entering phase three, they'll be expanding to a much larger group of patients across multiple different centers over a longer duration. That's when we'll really see how the body reacts; I guess there's always a chance some nasty side effects might show up, though none have been reported so far. I also happened to see somewhere that their stock price has taken quite a jump, so here is the chart...
http://www.nasdaq.com/asp/quotes_rep...&selected=OSIRAs you can tell, Wall Street definitely recognized these positive research results. Since mid-October 2008, the stock has climbed from $11 to $21 per share. It's worth keeping in mind the kind of recession the world was dealing with back then, too. Sometimes, a move like this can be quite telling. 🙂
