In planarians, they stick around into adulthood, where they become known as adult pluripotent stem cells or neoblasts. Scientists believe these neoblasts hold the secret to regeneration.

For instance, mortalin was shown to be constitutively expressed in planarian neoblasts, and its experimental silencing resulted in inability to regenerate and maintain the normal cell turnover (Conte et al., 2009).

Gut regeneration in holothurians: a snapshot of recent developments

In uninjured planaria, neoblasts are distributed throughout the parenchyma (mesenchyme), and only mitotic cells serve as the source of replacement cells during tissue renewal (Newmark, 2007).

Histological investigations have suggested that the remarkable size of these hyperplasic ovaries versus normal ovaries is due to a greater proliferation of neoblasts transforming into oogonia (Gremigni and Banchetti, 1972; Benazzi, 1974).

Dynamics of cytokine-like activity in the hyperplasic ovary of ex-fissiparous planarians

The epithelium is disordered, with most gonial cells (or neoblasts) and scarce sperm cells in the tubule lumen.

The ability to follow individual neoblasts opens the door to uncovering the molecular cues that help planarian stem cells navigate to the site of injury and ultimately may allow scientists to provide therapeutic stem cells with guideposts to their correct destination.

Tracking regenerative stem cells in the flatworm

Scattered within the planarian body, neoblasts apparently remain in an unspecialized, stem cell state, which enables them to differentiate into any cell type.

This amazing plasticity relies on the presence of a population of adult pluripotent stem cell, the neoblasts, which are able to become any type of cell.
