Imaging technologies have undergone explosive growth over the past few decades and now play a central role in all walks of cancer research. Modern imaging techniques allow clinicians and researchers to not only see where a tumor is located in the body, but also to visualize the expression and activity of specific molecules and biological processes that influence tumor behaviour and/or response to therapy. 

In this list, we pay homage to 9 of the most incredible images we’ve seen from the field of cancer research.

In this image from a genetically engineered mouse model, lung cancer driven by the Kras oncogene shows up in purple. As a key driver in many types of cancer, the Kras gene makes a promising target for new cancer therapies. 

2. HeLa cells

HeLa (cancer) cells captured at 300x magnification with 2-photon fluorescence. Stained with the actin binding toxin phalloidin (red), microtubules (cyan) and cell nuclei (blue) and taken on a Nikon RTS2000MP custom laser scanning microscope.

3. Hurricane in a Cell

This image shows a polyploid giant cancer cell (PGCC) from triple-negative breast cancer. PGCCs, a subtype of cancer cell, appear in a variety of solid tumors and appear to help the tumor invade surrounding tissues and migrate to other areas of the body (metastasis). Researchers would like to better understand how PGCCs form and function with the goal of improving treatments. Actin is red; mitochondria are green; nuclear DNA is blue.

4. Neuroblastoma bone marrow metastatic neutrospheres

5. A developing mouse mammary gland

The image shows a section of a developing wildtype mouse mammary gland immunostained for vimentin (red), beta-catenin (green) and DNA (blue). This is an example of a control image for experiments demonstrating the functions of the Elf5 protein. 

6. A blood vessel in a melanoma

Colour-enhanced, freeze-fracture scanning electron micrograph of a blood vessel that has grown into a melanoma and is providing nourishment to it. Numerous red blood cells (coloured red) and three white blood cells (coloured yellow) can be seen within the blood vessel (coloured yellow/green). This is surrounded by the melanoma (coloured brown) which is from mouse skin. Horizontal width of image is approximately 230 micrometres.

7. Where tumor cells enter the bloodstream

On the left, stained red blood vessels weave between florescent green tumor cells. On the right, the researchers have mapped exactly where tumor cells (white) have entered blood vessels. The image shows that more cells enter blood vessels in the tumor's core than its invasive border.  Maximum projection images of individual microtumors and tumor-adjacent areas were prepared from z stacks acquired with a confocal Zeiss microscope at 20× or 40×. The z stacks were stitched and rendered 3D to outline and mask the volume of signals for total vasculature and tumor cells.

8. Treating triple negative breast cancer

This image shows a triple-negative breast cancer cell undergoing retraction and apoptosis (cell death) after treatment with a combination of the chemotherapy drug cisplatin and a mitochondrial division inhibitor drug called mdivi-1. Actin in red; mitochondria in green; nuclei in blue. Understanding how drugs work at the molecular level contributes to better cancer treatments.

9.  Tracking the Sox10 gene

Organoids are miniature versions of organs grown in the lab. Organoid culture systems offer a powerful platform for the development of targeted therapies and precision medicine by letting scientists easily create genetic or environmental changes (difficult or impossible in animal models or human patients) to identify networks of genes that control cellular behaviors that give way to tumors. This image shows an organoid that was grown from a single mammary stem cell. Researchers used this system to demonstrate how a single critical gene, called Sox10 (in blue), controls whether cells turn into dangerous mini "factories", rapidly churning out more copies and variants of themselves. The Sox10 gene allows cells to migrate and to take on characteristics of other cells (plasticity). In cancer cells, these features lead to metastasis and drug resistance. Inner keratin-8+ luminal cells (in green) are surrounded by peripheral keratin-14+ basal cells (in red).
