Biotecnología Celular
Desarrollo de Terapias Avanzadas como CAR T, virus oncolíticos o Terapias Celulares Investigación en Cáncer Infantil. Esta línea pone su principal foco en el desarrollo de inmunoterapias, aunque también estudiamos el desarrollo y evolución de los tumores sólidos, especialmente sarcomas infantiles. Desarrollo de Terapias Celulares en Enfermedades Raras. Esta línea se basa, principalmente, en la utilización de células progenitoras mesenquimales como tratamientos en patologías de base inmune o regeneración de tejidos mesodérmicos.
