What is Regeneration?
Regeneration refers to the process of tissue renewal, restoration and growth that makes cells, genomes, organisms and ecosystems resilient to natural events that result from perturbations. Furthermore, every species is capable of regeneration, from bacteria to giant elephants. Also, regeneration can be either complete or incomplete type. Complete regeneration occurs when the new tissue is identical to the lost tissue. In contrast, incomplete regeneration is where necrotic tissue is followed by the process of fibrosis. At its most elementary level, regeneration is mediated by molecular processes of gene regulation—morphogenesis, cell proliferation, and cell differentiation.
Hydra and planarian flatworms have long been model organisms for their regenerative abilities that are highly adaptive in nature. When they receive a wound, their cells become activated, resulting in the organ returning to its original position. Furthermore, regeneration of limbs is a common adaptive capacity practiced by metazoan creatures.
Difference Between Fragmentation and Regeneration
Fragmentation and regeneration are two unique processes that enable organisms to multiply and develop in various ways. Fragmentation is a type of asexual reproduction in which an organism divides into fragments, each of which develops into a new, identical individual. Whereas, the process by which an organism grows back missing body parts is called regeneration. This process can happen naturally as an organism grows and develops or in reaction to harm or injury. In this article, we will look into the differences between fragmentation and regeneration in detail.
