English: We can study how organs grow and regenerate by dissecting out their cellular components and grow them in vitro, in the lab. The picture shows a specific type of cellular tissue from embryonic salivary glands of mouse, called epithelium, that differentiates into the functioning organ (salivary gland) under certain conditions. In the laboratory, we can dissect out the embryonic organs, culture its separated components, and add growth factors to the culture conditions that will simulate normal growth, stimulate cellular growth and tissue regeneration. The picture is a confocal microscopy image showing cells of the epithelium of an embryonic salivary gland (a marker for these cells is used to label them in blue) and the growing cells (labeled in red/pink) that proliferate in the tip of the tissue, which drives its elongation and further formation of ducts and other specialized tissue structures important for functionality of the organ.
