Evolutionary Loss of Animal Regeneration: Pattern and Process

Bridges between Evolutionary Pattern and Process

Uc Pinna and Sallcs ask lor clarification on how cladistic analysis tests adaptational hypotheses de Pinna and Sallcs. 1990; Coddington, 1988 . They also [joint out that an alternative optimization exists lor character 3 in my 19881 fig. 2. Ynp. OK, I'll admit it. All readers of the previous paper are hereby instructed to believe that a new laxon has been discovered, identical to taxon D except...

Hair loss and regeneration performed on animal models

Research in the field of reversal hair loss remains a challenging subject. As Minoxidil 2% or 5% and Finasteride are so far the only FDA approved topical treatments for inducing hair regrowth, research is necessary in order to improve therapeutical approach in alopecia. In vitro studies have focused on cultures of a cell type - dermal papilla or organ culture of isolated cell follicles. In vivo...

Complexity, pattern, and evolutionary trade-offs in animal aggregation.

One of the most striking patterns in biology is the formation of animal aggregations. Classically, aggregation has been viewed as an evolutionarily advantageous state, in which members derive the benefits of protection, mate choice, and centralized information, balanced by the costs of limiting resources. Consisting of individual members, aggregations nevertheless function as an integrated whol...

Retrotransposons in animal regeneration

Research on the involvement of retroelements in developmental processes has been gaining momentum recently; however, most of the studies published so far have been focused on embryonic development. This commentary presents two recent papers, which document significant changes in transcriptional activity of retroelements in two different model systems, salamander limb regeneration and regenerati...
