DMPK and myotonic dystrophy type 1: We therefore expected the myogenic potential to decrease with an increased number of CTG triplets in DMPK. In fact, pericytes isolated from FSHD patients showed normal morphology and proliferation, but impaired differentiation correlated with overall disease severity.48, 49 Even though many variables differ between individuals in our diverse cohort, DM1 disease status, age, and sex did not influence isolation, proliferation, or differentiation abilities of pericytes.
