Beyond mammals: the evolution of chewing and other forms of oropharyngeal food processing in vertebrates

open access: yesBiological Reviews, EarlyView.
ABSTRACT Oropharyngeal food processing exhibits a remarkable diversity among vertebrates, reflecting the evolution of specialised ‘processing centres’ associated with the mandibular, hyoid, and branchial arches. Although studies have detailed various food‐processing strategies and mechanisms across vertebrates, a coherent and comprehensive terminology ...

Dental stem cells: Dentinogenic, osteogenic, and neurogenic differentiation and its clinical cell based therapies

open access: yesIndian Journal of Dental Research, 2012
Each year approximately 400 billion is spent treating Americans suffering some type of tissue loss or end-stage organ failure. This includes millions of dental and oral craniofacial procedure, ranging from tooth restorations to major reconstruction of ...

Reading hominin life history in fossil bones and teeth: methods to test hypotheses regarding its evolution

open access: yesBiological Reviews, EarlyView.
ABSTRACT Human life history is derived compared to that of our closest living relatives, the great apes. It has been suggested that these derived traits are causally related to aspects of our ecology, social behaviour and cognitive abilities. However, resolving this requires that we know the evolutionary trajectory of our distinctive pattern of growth,

Rodent monocyte‐derived macrophages do not express CD163: Comparative analysis using macrophages from living boreoeutherians

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background CD163 is a scavenger receptor predominantly expressed on the surfaces of macrophages in various mammalian species and is a marker of anti‐inflammatory (M2‐like) macrophages. High density of CD163‐positive tumor‐associated macrophages (TAMs) is associated with worse prognosis in various patient tumors.

Combinatorial expression of glial transcription factors induces Schwann cell‐specific gene expression in mouse embryonic fibroblasts

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background Schwann cells provide peripheral nerve trophic support, myelinate axons, and assist in repair. However, Schwann cell repair capacity is limited by chronic injury, disease, and aging. Schwann cell reprogramming is a cellular conversion strategy that could provide a renewable cell supply to repair injured nerves.

Characterization of Neurogenic Potential of Dental Pulp Stem Cells Cultured in Xeno/Serum-Free Condition: In Vitro and In Vivo Assessment

open access: yesStem Cells International, 2016
Neural stem cells (NSCs) have a high potency for differentiation to neurons and glial cells for replacement of damaged cells and paracrine effects for the regeneration and remyelination of host axons.

Decreasing NF-κB expression enhances odontoblastic differentiation and collagen expression in dental pulp stem cells exposed to inflammatory cytokines.

open access: yesPLoS ONE, 2015
Inflammatory response in the dental pulp can alter the collagen matrix formation by dental pulp stem cells and lead to a delay or poor healing of the pulp.

Dental development in the tropical gar (Atractosteus tropicus) and the evolution of vertebrate dentitions

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background Dentitions have diversified enormously during vertebrate evolution, involving reductions, modifications, or allocations to prey seizing and processing regions. A combination of ancient and novel features related to dental and oropharyngeal apparatuses is found in extant lineages of non‐teleost fishes, such as the gars.

The Angiogenic Potential of DPSCs and SCAPs in an In Vivo Model of Dental Pulp Regeneration

open access: yesStem Cells International, 2017
Adequate vascularization, a restricting factor for the survival of engineered tissues, is often promoted by the addition of stem cells or the appropriate angiogenic growth factors.
