Deadly Beauty - 5 stunning images of malignant tumours



breast cancer

 

Breast Tumor Microenvironment  - This image of a breast cancer tumor and its microenvironment was obtained from a live mouse model using multiphoton microscopy and endogenous fluorescence. That is, the image was obtained without any fluorophores, stains, or dyes, using only the metabolic co-factors of NADH and FAD, which are already inside of cells, along with second harmonic generation to see collagen. This technique has important clinical potential for patients who require label-free imaging, and may lead to more effective diagnoses and treatments. Tumor cells display in cyan, macrophages in red, collagen fibers in green.

colon cancer


Colon Cancer Cells - Human colon cancer cells with the cell nuclei stained red and the protein E-cadherin stained green. E-cadherin is a cell adhesion molecule and its loss signals a process known as the epithelial-mesenchymal transition in which cells a cquire the ability to migrate and become invasive.

pancreatic cancer

 

Mitochondrial Dynamics in Pancreatic Cancer : This image shows mitochondrial staining (red) and nuclear staining (blue) of abnormal pancreatic ducts from a mouse model of human pancreatic ductal carcinoma. Mitochondrial shape changes occur throughout the progression of pancreatic cancer and the machinery that regulates the dynamics of mitochondria may be a promising new therapeutic target in the fight against this disease.

lung cancer

 

Lung Cancer Metastasis : This image shows how lung cancer cells invade surrounding tissues and start to spread (metastasis). These lung cancer cells have a mutation of a gene called LKB1 (in green) that promotes invasion. Actin, a cytoskeletal protein, is in red, and the cell nucleus is blue. These H157 lung cancer cells are expressing a GFP-tagged piece of LKB1 to disrupt its normal function. Spheroids of these cells were embedded in a 3-D collagen matrix with cells invading for 24 hours.
