Diabetic Type I and Type II Human Skeletal Muscle Myoblasts (HSMM) are isolated from donors diagnosed with either Diabetes Type I or Diabetes Type II. Additional donor information is available by contacting Scientific Support. Diseased cells are tested in the same SkGM™-2 Skeletal Muscle Growth Media as the normal cells allowing for easy comparisons between diseased and normal tissue. Both are sold in second passage.
