Title: Biomimetic materials to control neuroblastoma progression
Abstract
In this project, we will design an innovative biomaterial capable of mimicking in vitro the chemical and mechanical properties of the microenvironment of a pediatric tumor called neuroblastoma. Due to the great heterogeneity of this tumor, there is no specific treatment for high-risk neuroblastoma patients, apart from surgery and multiple cycles of chemotherapy. Testing the sensitivity of a patient's cells to a specific drug in vitro prior to treatment could be a major step forward in the direction of personalized therapy. To avoid altering cell responses due to different in vitro/vivo conditions, we aim to recreate the natural environment of neuroblastoma cells to approximate natural conditions of growth and response to treatment. We also aim to study the effect of a specific family of growth factors (bone morphogenetic proteins and transforming growth factors) as potential inhibitors of neuroblastoma growth. These growth factors will be presented to the cells not in solution, but fixed and oriented on a biomimetic material to approximate in vivo conditions in tumor tissue. At the end of the project, we will be able to propose new strategies for treating this pediatric cancer.
