Application of histochemical stains in anatomical research: A brief overview of the methods

Background In anatomical research, there is often a need to present complex topographical relationships in more detail, under magnification, beyond the scope of gross anatomy. However, more than magnification is often needed to better understand the arrangement of small anatomical structures. Special stains allow for the differentiation of connective tissue stroma and mutual relations between small structures such as blood vessels and nerves. Aim This review presents selected histochemical methods that can be applied in anatomical research. Such a concise outline can be both a compendium of knowledge for beginning researchers and an inspiration for anatomists and clinicians exploring the human body's details. Conclusions The advantage of histochemical staining is its relatively low cost and the large amount of information that can be obtained with their use.
