Which of the following cells helps to carry out regeneration?

Regeneration is carried out by specialized cells, which can proliferate at a fast rate. Also, they can form all the different cells that are required to form the body part that the organism needs to regenerate. Broken cells may not proliferate while “all cells” cannot have the above mentioned specialized features. Differentiated cells take up a fixed role and may not be able to produce all the cells required in regeneration.
