Final answer:
Regeneration in the mammalian liver is an example of tissue regeneration which is when fully differentiated cells proliferate to become a mass tissue that is equivalent, but not identical, to the lost mass of tissue.
Step-by-step explanation:
Regeneration in the mammalian liver is an example of tissue regeneration, a process where fully differentiated cells proliferate to replace lost tissue. Unlike fragmentation, which can lead to the formation of a new individual, tissue regeneration in mammals typically involves the restoration of the original function of the organ without the creation of a new organism. Stem cell research is essential in understanding how adult stem cells aid in this process, often focusing on their ability to divide and differentiate to renew and repair tissues. The liver has a remarkable capacity for regeneration, which is not an identical replication of the lost tissue but rather a restoration that allows for the continuation of function. The process involves inflammation, tissue repair with fibroblasts depositing collagen, and ultimately, the regeneration of liver cells.
