DNA screening and protein analyses in the Dmdmdx/Largemyd model. (A) DNA screening for the injected cells: PCR for the Large normal allele (162 bp) in the injected mice. Animals 1 and 2 were injected with cells, and animal 3 with PBS. Columns: 1, heart; 2, gastrocnemius; 3, stomach; 4, quadriceps; 5, diaphragm; 6, tail. Positive control (162 bp) and molecular weight (MW) are shown. (B) Dystrophin western blot analysis from different muscles from the mASC-injected and PBS-injected animals, reacted with antibody to dystrophin (H300, Santa Cruz Biotechnology, Inc.). Column 1, molecular weight; 2, normal human muscle; 3, normal C57BL muscle. Muscles from Dmdmdx/Largemyd mouse 1: column 4, gastrocnemius; 5, quadriceps; 6, diaphragm; 7, heart; 8, stomach. Muscles from Dmdmdx/Largemyd mouse 2: 9, gastrocnemius; 10, quadriceps; 11, diaphragm; 12, heart; 13, stomach. Muscles from Dmdmdx/Largemyd mouse 3: 14, quadriceps; 15, diaphragm. (C) Dystrophin immunofluorescence analysis in a normal control and in one injected muscle: Dmdmdx/Largemyd mouse 2, muscle gastrocnemius.
