A defining feature of vertebrates (craniates) is a pronounced head that is supported and protected by a robust cellular endoskeleton. In the first vertebrates, this skeleton probably consisted of collagenous cellular cartilage, which forms the embryonic skeleton of all vertebrates and the adult skeleton of modern jawless and cartilaginous fish. In the head, most cellular cartilage is derived from a migratory cell population called the neural crest, which arises from the edges of the central… Expand
Somite Compartments in Amphioxus and Its Implications on the Evolution of the Vertebrate Skeletal Tissues
TLDR
The finding of SPARC-expressing skeletal scaffold in amphioxus further supports previous hypothesis regarding SPARC gene family expansion in the elaboration of the vertebrate mineralized skeleton and demonstrates a conserved role for BMP signaling pathway in somite patterning of both Amphioxus and vertebrates. Expand
Tracing the evolutionary origin of vertebrate skeletal tissues: insights from cephalochordate amphioxus.
TLDR
It is proposed that upon the foundation of this collagenous precursor, novel tissue mineralization genes that arose from gene duplications were incorporated into an ancestral mesodermal GRN that makes connective and supporting tissues, leading to the emergence of highly-mineralized skeletal tissues in early vertebrates. Expand
The origin and evolution of vertebrate neural crest cells
TLDR
It is suggested that at least some of the regulatory components of early stages of neural crest development long pre-date vertebrate origins, perhaps dating back to the last common bilaterian ancestor. Expand
Lamprey Lecticans Link New Vertebrate Genes to the Origin and Elaboration of Vertebrate Tissues
TLDR
The phylogeny, genomic arrangement, and expression patterns of all lecticans in the sea lamprey suggest the ancestral pre-duplication lectican had a complex expression pattern, functioned to support mesenchymal histology, and likely played a role in the evolution of vertebrate-specific cell and tissue types. Expand
Lamprey lecticans link new vertebrate genes to the origin and elaboration of vertebrate tissues.
TLDR
The phylogeny, genomic arrangement, and expression patterns of all lecticans in the sea lamprey suggest that the ancestral pre-duplication lectican had a complex expression pattern, functioned to support mesenchymal histology, and likely played a role in the evolution of vertebrate-specific cell and tissue types.

Insights into Neural Crest Evolution
TLDR
DiI-labeling shows that trunk neural crest-derived cells, likely homologous to mammalian Schwann cell precursors, contribute to the lamprey enteric nervous system, potentially representing the most primitive form of neural crest cells contribution to the ENS. Expand
Acquisition of multipotent and migratory neural crest cells in vertebrate evolution.
TLDR
A brief overview of mechanisms that might explain how ancestral NC-like cells acquired the multipotency and migratory capacity seen in vertebrates are provided. Expand
The origin and diversification of the developmental mechanisms that pattern the vertebrate head skeleton.
TLDR
This review surveys what is currently known about the cell biology and gene expression during head development in modern vertebrates, allowing us to better characterize the developmental genetics driving head skeleton formation in the most recent common ancestor of all living vertebrates. Expand
On the evolutionary relationship between chondrocytes and osteoblasts
TLDR
Comparative transcriptomics may revolutionize understanding of not only the clade-specific evolution of skeletal cells, but also the generation of evolutionary novelties, providing a modern paradigm for the evolutionary process. Expand

TLDR
In this review, the history of the study on the evolution of the chordate mesoderm is summarized, followed by a review of the current understanding of genetic mapping on anterior/posterior (A/P) mesodermal patterning between chordates and a direct developing hemichordate (Saccoglossus kowalevskii).

Insights from Amphioxus into the Evolution of Vertebrate Cartilage
TLDR
The results suggest that neural crest-derived cartilage evolved by serial cooption of genes which functioned primitively in mesoderm, and not by single amphioxus orthologs of genes involved in neural crest chondrogenesis. Expand

TLDR
A stepwise model for the evolution of NCCs involving heterotopic and heterochronic activation of ancient ectodermal gene programs and new responsiveness to preexisting inducing signals is proposed in light of the phylogenetic distribution of neural crest‐like cells, the deep homology of developmental gene networks, and the central role of evolutionary loss in deuterostome evolution.

Roles for FGF in lamprey pharyngeal pouch formation and skeletogenesis highlight ancestral functions in the vertebrate head
TLDR
The results suggest that these roles for FGFs arose in the first vertebrates and that the evolution of the jaw and gnathostome cellular cartilage was driven by changes developmentally downstream from pharyngeal FGF signaling. Expand

TLDR
It is proposed that the common ancestors of chordates possessed a genetic regulatory system that was the prototype of chondrogenesis and osteogenesis in vertebrates, resulting in the emergence of cartilage and mineralized bone. Expand
Importance of SoxE in neural crest development and the evolution of the pharynx
TLDR
The results show that chondrogenic function of SoxE regulators can be traced to the lamprey–gnathostome common ancestor and indicate that lamprey SoxE genes might have undergone independent duplication to have distinct functions in mandibular versus caudal branchial arches. Expand
Conservation and elaboration of Hox gene regulation during evolution of the vertebrate head
TLDR
Evidence is presented for the conservation of cis-regulatory mechanisms controlling gene expression in the neural tube for half a billion years of evolution, including a dependence on retinoic acid signalling. Expand
The unusual cartilaginous tissues of jawless craniates, cephalochordates and invertebrates
TLDR
New morphological and biochemical information on the cartilaginous tissues in squid, horseshoe crab and amphioxus reveals the presence of CNBr-insoluble, non-collagenous matrix proteins, potentially extending the jawless craniate family of cartilagenous proteins into the invertebrates. Expand
Fgf signalling is required for formation of cartilage in the head.
TLDR
It is shown that inhibition of FGF receptor activity in the zebrafish embryo following neural crest emigration from the neural tube results in complete absence of neurocranial and pharyngeal cartilages, and this data implicate Fgf3 and FgF8 as key regulators of cartilage formation in the vertebrate head.

TLDR
Results indicate that the pharyngeal endodermal cells are responsible for secretion of the cartilage in hemichordates, whereas in lancelets, all the pharygeal cells surrounding the gill bars, ectodermal, endodmal, and mesodermal may be responsible for cartilage formation. Expand
