There are a few, but like RealMD said, tuition and costs are already pretty low (comparably) for in-staters. However, each school does have a small pool of scholarship money for student recruitment. UTMB, A&M, and UTSW are the only schools I know of for a fact.
However, I didn't see anything more than 5K a year (renewable) during my application cycle.
And when it comes to scholarships, it usually helps if they think you're highly sought after (i.e. hold multiple out of state acceptances from highly desirable programs).
Best of luck to the c/o 2013. 👍
