Breathing in water 2021/2022

Histology is the branch of biology that studies the anatomy of biological tissues. It is through comparative studies of healthy and pathological tissues that we can arrive at a series of diagnoses. For better microscopic visualization of tissue and cell structures, most of which are colorless, they need to be stained. The most commonly used staining technique uses the hematoxylin and eosin dyes, allowing various components of the cells and the extracellular matrix to be defined quite well. In this collection, BREATHE IN WATER, we have created fun patterns based on images of histological sections of Sparus aurata (commonly known as sea bream) gills, stained with hematoxylin and eosin. The gills are respiratory organs where gas exchange takes place between the water and the blood or lymph of aquatic animals, allowing them to BREATHE IN THE WATER.
