4 de oct. de 2018 · Planarians are flatworms capable of dramatic feats of regeneration, which have been studied for over two centuries. Recent findings identify key cellular and molecular principles underlying these feats.
10 de jul. de 2022 · Recent studies have shown that planaria can regenerate all tissue parts. Various signalling pathways and molecular mechanisms play important roles in the regeneration process of planarians. It is these organized specific regulation that enables planarians to accurately regenerate appropriate tissues after injury.
La regeneración en planarias son metazoos bilaterados acelomados cuya asombrosa capacidad regenerativa ha sido ampliamente investigada debido a sus potenciales aplicaciones clínicas y biotecnológicas. 1 La regeneración de las planarias es básicamente epimórfica ya que depende de la proliferación de los neoblastos (células madre ...
9 de nov. de 2012 · A single pluripotent adult stem cell type (“neoblast”) gives rise to the entire range of cell types and organs in the planarian body plan, including a brain, digestive-, excretory-, sensory- and reproductive systems. Neoblasts are abundantly present throughout the mesenchyme and divide continuously.
19 de oct. de 2023 · Regenerative abilities vary dramatically across animals. Even amongst planarian flatworms, well-known for complete regeneration from tiny body fragments, some species have restricted...

Planarian regeneration involves the generation of new tissue at the wound site via cell proliferation (blastema formation), and the remodeling of pre-existing tissues to restore symmetry and proportion (morphallaxis).
