Treatment of muscular dystrophy mouse model

Human dystrophin gene is a large gene which is composed of 2.4Mb and 79 exons. We have inserted the gene into the HAC vector, and introduced it to mouse cells. The cell transplantation into a dystrophy mouse model improved the dystrophy symptoms. (PubID:21849666)

  1. Extraction of mdxMABs from mdx
  2. Introduction of DYS-HAC into MABs by MMCT
  3. Selection of cells containing DYS-HAC, followed by infection of the cells with lenti virus expressing MyoD and nLacZ
  4. in vitro evaluation (selection of clones, evaluation of proliferation and differentiation)
  5. After the selection process (as in 4), transplant the cells into SCID/mdx mouse
  6. Dystrophin gene expression, morphology analysis, and evaluation of functional recovery

Gene expression analysis of cells carrying DYS-HAC

Western blotting was conducted to monitor the expression of dystrophin protein (Dys 427 kDA)
  • control mouse expressed dystrohin protein (Dys) (right:Untreated SCID)
  • muscular dystrophy mouse model did not show Dys protein expression(center: Untreated SCID/mdx)
