There's been threads about this before. Certain DO/PhD programs call themselves Medical Scientist Training Programs, confusing some applicants and posters here. There are no DO/PhD NIGMS MSTPs (or even fully-funded programs for that matter). However, there's no trademark. There's nobody who's going to come after them for using the term. Nevertheless, I always ask that to avoid confusion on this forum that only the NIGMS MSTPs are called MSTPs. Of course you are being trained to become a medical scientist, and I'm not going to sit here and tell you not to use the term. I'm just trying to present an unbaised opinion.
