| abstract |
The invention relates to the field of genetic recombination and stein cell application. In particular, the invention provides a construct for expressing a soluble fragment of a secretory TRAIL, and a lentiviral expression vector comprising the construct. The present invention also provides a mesenchymal stein cell in which the construct is integrated into the genome, which can express and secrete the TRAIL fragment. The invention also provides the use of the construct or vector or mesenchymal stein cells for the treatment of brain tumors. |
