Document Summary

Salamander questions: regeneration is the restoration or new growth by an organism of organs, tissues, etc. , that been lost, removed or injured. T cells: a totipotent cell has the potential for developing in various, specialized ways in response to internal or external stimuli. A pluripotent cell is capable of differentiating into different types of body cells, and a unipotent cell is capable of developing into only one type of cell or tissues, and totipotent cells are used in regeneration. In salamanders, the regeneration process begins immediately after amputation. After the limb is lost, the epidermis migrates to cover the stump in less than 12 hours, forming a structure called the apical epidermal cap (aec). Over the next few days, there are changes in the stump tissues that result in the formation of a blastema (a mass of dedifferentiated proliferating cells).
