I was actually wondering the same thing. When the Ark kids barricade themselves in that one room at Mt. Weather, Monty's viewing the camera footage from the hallways and mentions that some people aren't wearing hazmat suits. To which Jasper replies that the treatments have already begun and are successful (sorry, I don't remember the exact wording he uses).

We can assume that the guards were the first batch of people who received the bone marrow treatment, and they were all pretty much killed by Bellamy or Octavia. But there had to have been other civilian volunteers - and not just the people they experimented on while they were first working on the treatment. I'm sure the doctor and Cage realized that their time was limited and they needed to treat as many people as possible.
