Regenerating the central nervous system: how easy for planarians!

Francesc Cebrià
Development Genes and Evolution
2007

The regenerative capabilities of freshwater planarians (Platyhelminthes) are very difficult to match. A fragment as tiny as 1/279th of the planarian body is able to regenerate a whole animal within… (More)

The BMP pathway is essential for re-specification and maintenance of the dorsoventral axis in regenerating and intact planarians.

2007

The bone morphogenetic protein (BMP) pathway has been shown to play an important role in the establishment of the dorsoventral axis during development in both vertebrate and invertebrate species. In… (More)

Planarian homologs of netrin and netrin receptor are required for proper regeneration of the central nervous system and the maintenance of nervous system architecture.

Conserved axon guidance mechanisms are essential for proper wiring of the nervous system during embryogenesis; however, the functions of these cues in adults and during regeneration remain poorly… (More)

The study of planarian regeneration may help us to understand how we can rebuild organs and tissues after injury, disease or ageing. The robust regenerative abilities of planarians are based upon a… (More)

Origin and evolutionary process of the CNS elucidated by comparative genomics analysis of planarian ESTs.

2003

Among the bilateral animals, a centralized nervous system is found in both the deuterostome and protostome. To address the question of whether the CNS was derived from a common ancestor of… (More)

Gradients in planarian regeneration and homeostasis.

Teresa Adell, Francesc Cebrià, Emili Saló
Cold Spring Harbor perspectives in biology
2010

Planarian regeneration was one of the first models in which the gradient concept was developed. Morphological studies based on the analysis of the regeneration rates of planarian fragments from… (More)

Regeneration and maintenance of the planarian midline is regulated by a slit orthologue.

Francesc Cebrià, Tingxia Guo, Jessica Jopek, Phillip A Newmark
Developmental biology
2007

Several families of evolutionarily conserved axon guidance cues orchestrate the precise wiring of the nervous system during embryonic development. The remarkable plasticity of freshwater planarians… (More)

Morphogenesis defects are associated with abnormal nervous system regeneration following roboA RNAi in planarians.

The process by which the proper pattern is restored to newly formed tissues during metazoan regeneration remains an open question. Here, we provide evidence that the nervous system plays a role in… (More)

The expression of neural-specific genes reveals the structural and molecular complexity of the planarian central nervous system

Francesc Cebrià, Tomomi Kudome, +4 authors Kiyokazu Agata
Mechanisms of Development
2002

Planarians are attractive animals in which various questions related to the central nervous system (CNS) can be addressed, such as its origin and evolution, its degree of functional conservation… (More)

Dissecting planarian central nervous system regeneration by the expression of neural-specific genes.

Development, growth & differentiation
2002

The planarian central nervous system (CNS) can be used as a model for studying neural regeneration in higher organisms. Despite its simple structure, recent studies have shown that the planarian CNS… (More)
