Rexeneración

As estrelas de mar rexeneran os seus membros.
Especie de lagarto rexenerando o rabo.

En bioloxía, a rexeneración[1] é o proceso de renovación, restauración, e crecemento que fai aos xenomas, células, organismos, e ecosistemas resilientes a acontecementos ou flutuacións naturais que causan perturbación ou dano.[2] Tódalas especies teñen capacidade de rexeneración, dende as bacterias até os humanos.[3][4] A rexeneración pode ser ora completa[5] onde o novo tecido é o mesmo que o tecido perdido,[5] ora incompleta[6] onde despois do tecido necrótico vén a fibrose.[6] No seu nivel máis elemental, a rexeneración está mediada por procesos moleculares de regulación xénica.[7][8] Porén, a rexeneración en bioloxía adoita facer referencia a procesos morfoxénicos que caracterizan os trazos de plasticidade fenotípica que permiten aos organismos multicelulares reparar e manter a integridade dos seus estados fisiolóxicos e morfolóxicos. Por enriba do nivel xenético, a rexeneración está fundamentalmente regulada por procesos celulares asexuais.[9] A rexeneración é diferente da reprodución. Por examplo, o xénero hydra realiza a rexeneración mais reprodúcese polo método da xemación.

Consultado o 2012-12-07. The new tissue is not the same as the tissue that was lost. After the repair process has been completed, there is a loss in the structure or function of the injured tissue. In this type of repair, it is common that granulation tissue (stromal connective tissue) proliferates to fill the defect created by the necrotic cells. The necrotic cells are then replaced by scar tissue.
