| abstract |
The invention relates to specific, regulatory sequence regions of the alpha smooth muscle actin gene (a-SMA gene), and fusion structures in which said regulatory sequence regions of the a-SMA gene are operationally linked to other functional nucleic acid sequences. The invention also relates to the use of said regulatory sequence regions for cell type specific and differentiation specific reporter expression, for cell type specific and differentiation specific gene changes (alteration, mutation) and for gene expression changes in cells and organisms. |
