Fate bias during neural regeneration adjusts dynamically without recapitulating developmental fate progression

Fate Decisions during Neural Crest Ontogeny

Cell fate determination during tooth development and regeneration.

Teeth arise from sequential and reciprocal interactions between the oral epithelium and the underlying cranial neural crest-derived mesenchyme. Their formation involves a precisely orchestrated series of molecular and morphogenetic events, and gives us the opportunity to discover and understand the nature of the signals that direct cell fates and patterning. For that reason, it is important to ...

Transcriptional reversion of cardiac myocyte fate during mammalian cardiac regeneration.

RATIONALE Neonatal mice have the capacity to regenerate their hearts in response to injury, but this potential is lost after the first week of life. The transcriptional changes that underpin mammalian cardiac regeneration have not been fully characterized at the molecular level. OBJECTIVE The objectives of our study were to determine whether myocytes revert the transcriptional phenotype to a ...

Fate predetermination of cardiac myocytes during zebrafish heart regeneration

Adult zebrafish have the remarkable ability to regenerate their heart upon injury, a process that involves limited dedifferentiation and proliferation of spared cardiomyocytes (CMs), and migration of their progeny. During regeneration, proliferating CMs are detected throughout the myocardium, including areas distant to the injury site, but whether all of them are able to contribute to the regen...

molecular interactions of lncrnas: cellular fate determination and tissue regeneration

lncrnas (long non-coding rnas) are responsible to control the degradation process, rna stability, orchestration, inhibition, transcription and histone modification etc. these rnas have been termed as the key agents of several mechanisms such as development, organogenesis and regeneration of damaged tissues etc. they interact with a number of partner molecules either protein, rnas or dnas and co...
