Regenerate to “Rejuvenate”: Insights From Adult Resident Stem Cells of Aged Flatworms and Mice
Resident stem cells from aged planaria and murine skeletal muscle possess some inherent abilities to mitigate signs of aging after tissue regeneration. ABSTRACT Adult resident stem cells are capable of regenerating tissues that manifest signs of “rejuvenation” in flatworms and mice of older ages.

Hedgehog signaling regulates gene expression in planarian glia
Hedgehog signaling is critical for vertebrate central nervous system (CNS) development, but its role in CNS biology in other organisms is poorly characterized. In the planarian Schmidtea mediterranea, hedgehog (hh) is expressed in medial cephalic ganglia

The pioneer factor Smed-gata456-1 is required for gut cell differentiation and maintenance in planarians [PDF]
How adult stem cells differentiate into different cell types remains one of the most intriguing questions in regenerative medicine. Pioneer factors are transcription factors that can bind to and open chromatin, and are among the first elements involved ...

Reduced Adult Neurogenesis in Humans Results From a Tradeoff Rather Than Direct Negative Selection
Embryonic radial glia (RG) generate neurons, glial cells, and later adult neural stem cells, which sustain adult neurogenesis (top, left to right). Human‐specific genetic modifications (blue arrow), selected to boost early RG neurogenic activity, may lead to premature RG exhaustion and reduced adult neurogenesis in the human brain (bottom).

Schmidtea mediterranea phylogeography: an old species surviving on a few Mediterranean islands? [PDF]
Background: Schmidtea mediterranea (Platyhelminthes, Tricladida, Continenticola) is found in scattered localities on a few islands and in coastal areas of the western Mediterranean. Although S.

Stem cells and fluid flow drive cyst formation in an invertebrate excretory organ.
Cystic kidney diseases (CKDs) affect millions of people worldwide. The defining pathological features are fluid-filled cysts developing from nephric tubules due to defective flow sensing, cell proliferation and differentiation.

DNA damage and tissue repair: What we can learn from planaria. [PDF]
Faithful renewal of aging and damaged tissues is central to organismal lifespan. Stem cells (SCs) generate the cellular progeny that replenish adult tissues across the body but this task becomes increasingly compromised over time. The age related decline
