These cells are biological raw materials, capable of continuous division and differentiation into any type of cell needed. Turritopsis dohrnii is a species of small jellyfish. When threatened by environmental stress or injured, they can revert to their infancy and start over again. They undergo a process called cellular transdifferentiation by which one type of cell is converted into another.
