Researchers from the Cancer Research UK (CRUK) have developed a virtual reality (VR) 3D model of cancer, which is expected to help increase the understanding of cancer and in the search for new treatment.
According to the BBC, the CRUK team took a 1mm cubed breast cancer tumor sample from a patient. The sample contained around 100,000 cells.
The team cut the tissue into wafer thin slices, scanned them, and stained the slices with markers to show their molecular make-up and DNA characteristics.
The tumor was rebuilt using virtual reality (VR), which was then analyzed within a VR laboratory.
The sample, taken from the lining of the breast milk ducts, could be studied in detail and from various angles, mapping each individual cell.
CRUK Cambridge Institute director Greg Hannon was quoted as saying: “No one has examined the geography of a tumour in this level of detail before; it is a new way of looking at cancer.”
To study the tumor, the researchers became ‘avatars’ within the ‘virtual’ laboratory, while the cancer was represented by a multi-colored mass of bubbles.
Within the virtual laboratory, the tissue sample could be magnified to appear several meters across even though it was about the size of a pinhead.
Using the VR system, the researchers were able to ‘fly through’ the cells to explore the tumor in detail.
Referring to cells that separated from the main group, Hannon said: “Here you can see some tumour cells which have escaped from the duct.
“This may be the point at which the cancer spread to surrounding tissue – and became really dangerous – examining the tumour in 3D allows us to capture this moment.”
CRUK chief scientist Karen Vousden said: “Understanding how cancer cells interact with each other and with healthy tissues is critical if we are going to develop new therapies.
“Looking at tumours using this new system is so much more dynamic than the static 2D versions we are used to.”
The VR system enables multiple users from anywhere in the world to examine the tumor.
The ‘virtual tumor’ project is part of CRUK’s Grand Challenge Awards.
