Use of a mesenchymal stem cell that expresses a suicide gene for the manufacture of a medicine to treat cancer, in which the suicide gene is a gene that codes for cytosine deaminase, in which the cytosine deaminase of the suicide gene converts 5 -fluorocytosine in 5-fluorouracil, in which the mesenchymal stem cell is a human mesenchymal stem cell isolated from bone marrow, peripheral blood or blood from the umbilical cord, and in which cancer is selected from brain cancer, breast cancer, cancer liver, pancreatic cancer, colorectal cancer and lung cancer.Uso de una celula madre mesenquimal que expresa un gen suicida para la fabricacion de un medicamento para tratar un cancer, en el que el gen suicida es un gen que codifica para citosina desaminasa, en el que la citosina desaminasa expresada del gen suicida convierte la 5-fluorocitosina en 5-fluorouracilo, en el que la celula madre mesenquimal es una celula madre mesenquimal humana aislada de medula osea, sangre periferica o sangre del cordon umbilical, y en el que el cancer se selecciona de cancer cerebral, cancer de mama, cancer de higado, cancer de pancreas, cancer colorrectal y cancer de pulmon.
