That's true- if wasn't clear if it had regenerative properties in the 'knitting together flesh' sense. I suppose most people who die in space are, well, ripped out into space and probably difficult to revive after such a death.
Still- the movie wasn't very clear on this point. And screw that commander who killed himself and hundreds of people just to save his daughter-- to be charitable I'm going to assume he didn't know the explosion would be as big as it was.
