Abstract: The invention relates to a chimeric gallinaceous bird embryo comprising both types of exogenous cells: a. At least one population of cancer cells, and b. At least one population of immune cells, wherein said exogenous cancer cells are present in at least one tissue of said embryo, and said exogenous immune cells are present in at least one tissue of said embryo and/or circulate in the blood vessels of said embryo.

Abstract: The invention concerns a gallinacean embryo in which cancer cells have been grafted within the embryo tissue, characterised in that the embryo is at a developmental stage between the HH10 and HH25 stages at the time of the grafting, wherein said cancer cells are not neuroblastoma cells and said cells form tumors inside the embryo.

Abstract: The present invention relates to a gallinaceous bird embryo into which human neuroblastoma cells have been grafted at the level of the neural crests. The invention also relates to a process for preparing such a gallinaceous bird embryo, and to a process for screening for therapeutic molecules intended for the treatment of a neuroblastoma tumor based on the use of this gallinaceous bird embryo.

Abstract: The present invention relates to DCC-fusion proteins, nucleic acid molecules encoding the DCC-fusion proteins, as well as methods for their production and their use in treatment of cancer such as colorectal cancer, NSCLC and metastatic breast cancer. The present invention also relates to methods of treating cancer such as colorectal cancer, NSCLC and metastatic breast cancer by administering DCC-fusion proteins.

Abstract: A method for inducing apoptosis of tumoral cells in a patient having cancer cells bearing Cell-adhesion molecule-related/Downregulated by Oncogenes (CDO) receptors and expressing Sonic Hedgehog (SHH), including administering to the patient an effective amount of an agonist of CDO's apoptotic function, wherein the agonist is selected from the group consisting of a CDO fragment, a fusion protein comprising a CDO fragment, an antibody against SHH, and an siRNA which is capable of inhibiting SHH expression, and related CDO fragments, fusion proteins comprising a CDO fragment, antibodies against SHH, and siRNAs which are capable of inhibiting SHH expression.
