A new strategy to study neuroblastoma

MCT Research Talks

Neuroblastoma is a cancer of the nervous system that primarily affects children aged 5 and younger. Although neuroblastoma accounts for only 5% of childhood cancers, it is responsible for approximately 15% of childhood cancer deaths. For children with high-risk neuroblastoma – children in which cancer has spread significantly – the outlook is extremely poor. Approximately 1 in 5 of these children will not respond to treatment, and of those that do, 50% will develop drug resistance leading, in many cases, to death.

Dr Olga Piskareva, an NCRC supported scientist and Honorary Lecturer at RCSI, has recently published a study describing a new way to grow cancer cells in the lab. Traditionally, researchers grow cancer cells in the flasks on the flat surface. This is not the way cells grow in the human body. Dr Piskareva in collaboration with Dr Curtin and Prof O’Brien has designed a new way to grow cancer cells that recreate their growth in 3 dimensions as in the human or mice body. They used special cotton wool like sponges as a new home for cancer cells and populated them with cancer cells. At the next step, they gave cells the drug at the different amount and checked what happened. In this system, cells responded only to the drug at doses used in the clinic or mice models.

This new strategy to grow cells on sponges should help to understand cancer cell behaviour better and accelerate the discovery and development of new effective drugs for neuroblastoma and other cancers. This, in turn, will make the outlook for little patients better and improve their quality of life.
