Chromogens are substances that have the ability to produce color in a biological or chemical system. They are widely used in various applications, such as staining and detection techniques in biological and medical research, colorimetry in chemical analysis, and dyeing in the textile industry. Chromogens can be natural or synthetic, and their properties and applications vary depending on their chemical structure and physical characteristics. The comparison of the various tendon tissue engineering approaches proposed to date is made, focusing on each of the elements required to obtain structures that allow adequate regeneration of the tendon: growth factors, cells, scaffolds and techniques for scaffold development.
