An image of the tissue distribution of specific mRNAs, proteins, enzymes, or antigens is conveniently obtained by "printing" the cut surface of a tissue section onto a suitable substrate film and developing the film with appropriate reagents. It is also possible to localize metabolites by tissue printing. Most plant tissues leave a physical print/impression with detailed anatomical information. Epidermal surfaces of growing organs can be printed without damaging the organ. We provide this review to encourage further use and further development of these convenient and helpful procedures.
