Planarians are a group of flatworms. Some planarian species have remarkable regenerative
abilities, which involve abundant pluripotent adult stem cells. This makes these worms a …

INTRODUCTION Understanding the differentiation of stem cells into the vast amount of cell
types that form the human body is a central problem of basic and medical science. The …

Planarians have a long history in the fields of developmental and regenerative biology.
These animals have also sparked interest in neuroscience due to their neuroanatomy …

Comparing newly obtained and previously known nucleotide and amino-acid sequences
underpins modern biological research. BLAST is a well-established tool for such …

The planarian Schmidtea mediterranea is an important model for stem cell research and
regeneration, but adequate genome resources for this species have been lacking. Here we …

Flatworms (Platyhelminthes) are a basally branching phylum that harbours a wealth of
fascinating biology, including planarians with their astonishing regenerative abilities and the …

Regenerative abilities vary dramatically across animals. Even amongst planarian flatworms,
well-known for complete regeneration from tiny body fragments, some species have …

RNA viruses are the only known RNA-protein (RNP) entities capable of autonomous
replication (albeit within a permissive host environment). A 33.5 kilobase (kb) nidovirus has …

The sexual strain of the planarian Schmidtea mediterranea, indigenous to Tunisia and
several Mediterranean islands, is a hermaphrodite,. Here we isolate individual …

Planarian flatworms maintain their body plan in the face of constant internal turnover and
can regenerate from arbitrary tissue fragments. Both phenomena require self-maintaining …
