Context:
Of course all avenues of stem cell research should continue, not least because work on embryos provides fundamental insights. But it pays to keep looking for new approaches, and nature's locker can often yield useful secrets. Though there are never easy answers, sometimes there are unexpectedly simple ones.
Not necessarily. A treasury is a place to keep things of value, particular things worth a great deal. A locker is simply a place to keep things, which no particular reference to their value. The term is orignally nautical--on board sailing ships, loose items would be strewn around by the action of the ship, so they are put into built in containers known as lockers. A large box built into the frames of the ship which is used to store ropes and cables is called the rope locker. So here, locker being used figuratively, it simply means the accumulation of naturally occuring things, many of which are currently unknown, and therefore considered to be secrets until research reveals them.
