Image: Fluorescent confocal image of tissue from a fruit fly larva by Dr Marta Fores Maresma, Postdoctoral Research Fellow – Cell Death and Immunity Team, Division of Breast Cancer Research
Fruit flies are a powerful organism to model tumour development and cancer formation. Here, the researchers are using a potent genetic tool on structures inside fruit fly larva to understand how cancer cells and normal cells interact to promote or prevent malignant growth.
Using a technique called fluorescent confocal microscopy, we can see proteins in cells that are genetically encoded to glow green when they come into contact with other cells, which here are glowing red.
Understanding how the tumour microenvironment influences cancer growth has been a long-standing question in the field. Researchers can use these glowing proteins as ‘contact sensors’ to manipulate and track interactions between cancer cells and others cells inside living organisms.

Image: 3D tumour spheroids of an aggressive soft tissue sarcoma, DSRCT, by Dr Stella Man, Higher Scientific Officer – Sarcoma Molecular Pathology Team, Division of Molecular Pathology
Desmoplastic Small Round Cell Tumours (DSRCT) are a rare and aggressive form of soft tissue sarcoma affecting children and young adults. A distinctive feature of this cancer and others is that they produce a lot of scar tissue, which researchers think helps protect them from treatment, meaning more intense chemotherapy and radiotherapy are needed. There are currently no targeted therapies available.
This image shows a 3D spherical ball of DSCRT cells, called a tumour spheroid, taken from a patient’s tumour and grown in the lab. The tumour cells in green are surrounded by the protective scar tissue cells, coloured red, which mimics the tumour structure seen in patients.
Growing mini-tumours in this way allows researchers to study the interaction between cancer cells and its protective tissue in three dimensions, which could help find new treatment combinations for patients in the clinic.

Image: (Not) Lost in Translation – using human stem cells for brain tumour research by Sumana Shrestha, PhD Student – Paediatric Tumour Biology, Division of Clinical Studies
This image tells a story of the remarkable potential of human stem cells, which is helping brain tumour researchers to develop new therapies for the disease.
The cells in the background are neuroepithelial stem cells (NES cells) derived from embryo tissue, which are being used to model the development of the brain tumour medulloblastoma. Stem cells are the origin cells for all other cells in the body. They can be genetically manipulated or grown into more specialised cells in the lab to study their function, which can’t be done in the human brain.
The backdrop of this image is a filtered brightfield microscope image of NES cells – on top of this, regions of the cells have been shaded in. The picture shows a young woman with a surgical scar from brain tumour surgery, in green.
Inspired by the artists Ed Fairburn and James Cochran, who created a unique work of art using a laboratory pipette for the ICR’s Centre for Cancer Drug Discovery, this image highlights the bigger picture of how experimental stem cell research is providing insights to guide the development of new cancer therapies.

Image: Keeping an eye on cancer – implanted breast cancer cells by Sarah Ash, PhD Student – Molecular Cell Biology Team, Division of Breast Cancer Research
This image shows a breast cancer tumour growing below the skin of a mouse. The round mass of tumour cells in the middle is pushing upwards through layers of skin, recruiting cells called fibroblasts, coloured green, while developing its own blood supply to keep growing, coloured orange.
The structure of the developing tumour looks like an eye, which is ironic as the aim of the experiment was to “keep an eye” on the vascular blood supply and cancer-associated fibroblasts in these tumours as they develop over time.
The green stained fibroblast cells are expressing a protein called endosialin, which helps cancer cells enter the blood vessels and spread throughout the body. The protein here is being expressed at the earliest stages of tumour development, so targeting endosialin could help prevent tumours spreading in the first place.
Throughout the pandemic cancer researchers at the ICR have continued to “keep an eye on cancer” by studying how the environment around a tumour adapts over time and how we may target this to limit tumour development and spread with future therapies.
These eye-catching images illustrate just some of the cutting-edge research being carried out at the ICR, taken using sophisticated equipment purchased thanks to generous donations from our supporters.
From images like these our researchers are gaining unprecedented insights into the mechanisms that drive cancer, and new ways to target the disease to help treat patients.
