Advances in the Study of Pluripotent Stem Cells in Livestock

Cell Proliferation, EarlyView.
Livestock pluripotent stem cells include embryonic stem cells (ESCs) isolated from the inner cell mass of blastocysts and induced pluripotent stem cells (iPSCs) derived from somatic cell reprogramming. They hold significant potential for applications in livestock breed improvement, rapid propagation, human disease modelling and human organ ...

Direct comparison of distinct naive pluripotent states in human embryonic stem cells [PDF]

, 2017
Until recently, human embryonic stem cells (hESCs) were shown to exist in a state of primed pluripotency, while mouse embryonic stem cells (mESCs) display a naive or primed pluripotent state.

Hypertranscription of rDNA Responsible for Nucleolar Remodelling is a Doorman for Acquiring Pluripotency

Cell Proliferation, EarlyView.
Active nucleoli have the capability to release perinuclear heterochromatin, which is a novel event of iPSC reprogramming. ABSTRACT Ribosome biogenesis occurs within the nucleolus, with the initial step being the transcription of ribosomal DNA (rDNA). Although rDNA transcription is limited in somatic cells, it is more active in stem cells. Nevertheless,

Competence, specification and commitment in otic placode induction [PDF]

, 2000
The inner ear is induced from cranial ectoderm adjacent to the hindbrain. Despite almost a century of study, the molecular mechanisms of inner ear induction remain obscure. We have identified four genes expressed very early in the anlage of the inner ear,

Cell Movement patterns during gastrulation in the chick are controlled by positive and negative chemotaxis mediated by FGF4 and FGF8 [PDF]

, 2002
During gastrulation in amniotes, epiblast cells ingress through the primitive streak and migrate away to form endodermal, mesodermal, and extraembryonic structures.

Epigenetic control of cell identities from epiblast to gastrulation

The FEBS Journal, EarlyView.
In this review, we present and contextualize current knowledge about the roles of epigenetic modifiers during the development of mouse epiblast to gastrulation stage. The epigenetic regulation of enhancer and promoter elements by DNA methylation, histone modifications, and chromatin accessibility in concert with lineage‐specific transcription factors ...

Reviewing the benefits and clinical outcomes of oral fibroblasts over mesenchymal stem cells for repairing periodontal defects during or after orthodontic tooth movement

Periodontology 2000, EarlyView.
Abstract Orthodontic therapy applies forces to teeth, causing an inflammatory reaction in the periodontal ligament. This is repaired by remodeling of the periodontium, allowing tooth displacement. Although orthodontic therapy is mostly initiated during childhood and adolescence, the number of adults seeking this treatment is increasing as our society's

X-chromosome inactivation mosaicism in the three germ layers and the germ line of the mouse embryo [PDF]

, 1982
Electrophoretic variant forms of the X-linked enzyme phosphoglycerate kinase (PGK-1, E.C.2, 7, 2, 3) have been used to examine X-chromosome mosaicism in tissues from 121/2-day post coitum heterozygous female mouse embryos.

Germ cell and other tumors in individuals with differences in sex development

CA: A Cancer Journal for Clinicians, EarlyView.
Abstract Approximately one in 3500 to one in 5100 live‐born infants have atypical external genital development, known as differences in sex development (DSD). In 2005, an expert consensus conference thoroughly reviewed aspects of health care for individuals with DSD.

Remarks on taxonomy of some species of Elytrigia S.L. (Triticeae) in the light of embryo morphology

Acta Societatis Botanicorum Poloniae, 2014
Embryos of 21 accessions of the genus Elytrigia s.l. were studied. Characters of scutellum, coleoptile, coleorhiza and epiblast were taken into consideration. Correlation of characters proves an independence of epiblast organogenesis.
