Selfrenewing
Self-renewing describes the ability of a system to regenerate or replenish its own functional capacity, often without external replacement. In biology, the term is most closely associated with stem cells, which can divide to produce more stem cells while also generating specialized cells. This balance—self-renewal through symmetric divisions or maintenance of the stem cell pool via asymmetric divisions—is essential for tissue development, growth, and repair, and it depends on a supportive niche and signaling networks.
In multicellular organisms, self-renewal allows tissues such as blood, skin, and the intestinal lining to maintain
In plants, self-renewing tissues are found in meristems, such as the shoot and root apical meristems, which
Beyond biology, the term is used in materials science and sustainability to describe processes or systems capable
