Mature Mediastinal Teratoma [PDF]

Journal of Clinical and Diagnostic Research, 2015
A teratoma is a tumour with tissue or organ components resembling normal derivatives of more than one germ layer. We present a case of mediastinal mature teratoma as they have a low incidence rate.

Feedback Regulation of Signaling Pathways for Precise Pre-Placodal Ectoderm Formation in Vertebrate Embryos

Journal of Developmental Biology, 2022
Intracellular signaling pathways are essential to establish embryonic patterning, including embryonic axis formation. Ectodermal patterning is also governed by a series of morphogens.

AP-2α and AP-2β cooperatively function in the craniofacial surface ectoderm to regulate chromatin and gene expression dynamics during facial development

eLife, 2022
The facial surface ectoderm is essential for normal development of the underlying cranial neural crest cell populations, providing signals that direct appropriate growth, patterning, and morphogenesis.

An Alternative Splicing Program for Mouse Craniofacial Development

Frontiers in Physiology, 2020
Alternative splicing acts as a fundamental mechanism to increase the number of functional transcripts that can be derived from the genome – and its appropriate regulation is required to direct normal development, differentiation, and physiology, in many ...

Signalling pathway crosstalk stimulated by L-proline drives mouse embryonic stem cells to primitive-ectoderm-like cells

, 2023
The amino acid L-proline exhibits novel growth factor-like properties during development - from improving blastocyst development to driving neurogenesis in vitro. Addition of 400 µM L-proline to self-renewal medium drives naïve mouse embryonic stem cells

Hypohidrotic Ectodermal Dysplasia [PDF]

Medical Journal Armed Forces India, 2015
Ectodermal dysplasias are a heterogeneous group of disorders characterized by developmental dystrophies of ectodermal structures. These tissues include the skin, hair, nails, eccrine glands and teeth.1 Hypohydrotic Ectodermal Dysplasia is the most common type and is usually inherited as an X-linked recessive trait.

Genome-Wide Epigenetic Characterization of Tissues from Three Germ Layers Isolated from Sheep Fetuses

Frontiers in Genetics, 2017
DNA methylation of regulatory and growth-related genes contributes to fetal programming which is important for maintaining the correct development of three germ layers of the embryo that develope into different tissues and organs, and which persists into

Oral and Palatal Dentition of Axolotl Arises From a Common Tooth-Competent Zone Along the Ecto-Endodermal Boundary

Frontiers in Cell and Developmental Biology, 2021
Vertebrate dentitions arise at various places within the oropharyngeal cavity including the jaws, the palate, or the pharynx. These dentitions develop in a highly organized way, where new tooth germs are progressively added adjacent to the initiator ...
