Embryonic stem (ES) cells provide an invaluable tool for molecular analysis of vertebrate development and a bridge linking genomic manipulations in vitro and functional analysis of target genes in vivo. Work towards fish ES cells so far has focused on zebrafish (Danio renio) and medaka (Oryzias latipes). Here we describe the derivation, pluripotency, differentiation and growth responses of ES cell lines from Nile tilapia (Oreochromis niloticus), a world-wide commercial farmed fish. These cell lines, designated as TES1-3, were initiated from blastomeres of Nile tilapia middle blastula embryos (MBE)...

Meiosis is a central event of sexual reproduction. Like somatic cells, germ cells conduct mitosis to increase their cell number, but unlike somatic cells, germ cells switch their cell division mode from mitosis to meiosis at a certain point in gametogenesis. However, the molecular basis of this switch remains elusive. In this review article, we give an overview of the onset of mammalian meiosis, including our recent finding that MYC Associated Factor X (MAX) prevents ectopic and precocious meiosis in embryonic stem cells (ESCs) and germ cells, respectively...

This study explored the mechanism underlying the stimulation of collagen synthesis and osteoblastic differentiation by insulin-like growth factor 1 (IGF1) in primary mouse osteoblasts. Primary mouse calvarial osteoblasts were cultured and treated with various doses of IGF1 before transfection with siRNA targeting the collagen type I alpha 2 (Col1a2) or La ribonucleoprotein domain family member 6 (Larp6) genes. Alkaline phosphatase (ALP) activity, osteocalcin staining, alizarin red quantification and the expression level of runt-related transcription factor 2 (RUNX2) were performed to assess the differentiation of pre-osteoblasts...

Cell alignment and motility play a critical role in a variety of cell behaviors, including cytoskeleton reorganization, membrane-protein relocation, nuclear gene expression, and extracellular matrix remodeling. Direct current electric field (EF) in vitro can direct many types of cells to align vertically to EF vector. In this work, we investigated the effects of EF stimulation on rat adipose-tissue-derived stromal cells (ADSCs) in 2D-culture on plastic culture dishes and in 3D-culture on various scaffold materials, including collagen hydrogels, chitosan hydrogels and poly(L-lactic acid)/gelatin electrospinning fibers...

REVIEW
Hidehiko Inomata
The concentration gradient of morphogens provides positional information for an embryo and plays a pivotal role in pattern formation of tissues during the developmental processes. Morphogen-dependent pattern formations show robustness despite various perturbations. Although tissues usually grow and dynamically change their size during histogenesis, proper patterns are formed without the influence of size variations. Furthermore, even when the blastula embryo of Xenopus laevis is bisected into dorsal and ventral halves, the dorsal half of the embryo leads to proportionally patterned half-sized embryos...

Cells of our body are constantly exposed to physical forces such as tissue tension. In recent years, it has been shown that such mechanical signals greatly influence a number of cellular processes, including proliferation, differentiation, and migration. Conversely, cells maintain the mechanical properties of tissues by remodeling their own extracellular environment. To date, however, it is unclear about the molecular mechanisms to maintain the mechanical environment ("mechano-homeostasis") in which extracellular mechanical cues are integrated with cell proliferation and differentiation to ensure tissue, organ and body form...

How the shape and size of tissues and organs is regulated during development is a major question in developmental biology. Such regulation relies upon both intrinsic cues (such as signaling networks) and extrinsic inputs (such as from neighboring tissues). Here, we focus on pattern formation and organ development during Drosophila embryogenesis. In particular, we outline the importance of both biochemical and mechanical tissue-tissue interactions in size regulation. We describe how the Drosophila embryo can potentially provide novel insights into how shape and size are regulated during development...

For efficient respiration, tubular airways must be constructed with an optimal diameter and length for the dimensions of the body. In Drosophila, the growth of embryonic tracheal tubules proceeds in two dimensions, by axial elongation and diameter expansion. The growth forces in each dimension are controlled by distinct genetic programs and cellular mechanisms. Recent studies reveal that the apical cortex and the apical extracellular matrix filling the luminal space are essential for the generation, balancing, and equilibrium of these growth forces...

Hiroshi Sasaki
During preimplantation development, mouse embryos form two types of cells, the trophoectoderm (TE) and inner cell mass (ICM), by the early blastocyst stage. This process does not require maternal factors localized in the zygotes, and embryos self-organize at the blastocyst stage through intercellular communications. In terms of the mechanisms of cell fate specification, three historical models have been proposed: the positional model, and the original and newer versions of the polarity model. Recent studies have revealed that the intercellular Hippo signaling pathway plays a central role in the specification of the first cell fates...

REVIEW

Size distribution in a group of differentiated cells often falls into a constant range. However, in vitro and in vivo studies have shown that cells can temporarily change their size in response to their surrounding environment and the stimuli they receive. Thus, there must be a mechanism that normally keeps cell size constant while allowing a shift to an alternative size when necessary. To investigate the molecular basis of mammalian cell size control, we conducted a genetic screen in a human T cell line to identify genes involved in cell size regulation...

The chick embryonic eye is an excellent model for the study of vertebrate organogenesis. Key events in eye development involve thickening, invagination and cytodifferentiation of the lens primordium. While these events occur successively at different developmental stages, the extent to which these events are temporally related is largely unknown. Here we show that the lens invagination is highly sensitive to temperature. Lowering of incubation temperature to 29°C at embryonic day 2 delayed the onset of invagination of the lens, but not thickening and cytodifferentiation, leading to abnormal protrusion of the eye...

Histone variant H2A.Z promotes chromatin accessibility at transcriptional regulatory elements and is developmentally regulated in metazoans. We characterize the transcriptional and post-transcriptional regulation of H2A.Z in the purple sea urchin Strongylocentrotus purpuratus. H2A.Z depletion by antisense translation-blocking morpholino oligonucleotides during early development causes developmental collapse, in agreement with its previously demonstrated general role in transcriptional multipotency. During H2A...

To elucidate the mechanism for embryonic diapause or the breakdown of diapause in Bombyx mori, we biochemically analyzed nitric oxide synthase (NOS) during the embryogenesis of B. mori. The gene expression and enzyme activity of B. mori NOS (BmNOS) were examined in diapause, non-diapause, and HCl-treated diapause eggs. In the case of HCl-treated diapause eggs, the gene expression and enzyme activity of BmNOS were induced by HCl treatment. However, in the case of diapause and non-diapause eggs during embryogenesis, changes in the BmNOS activity and gene expressions did not coincide except 48-60 h after oviposition in diapause eggs...

CDC25B has been demonstrated to activate the complex of CDK1/Cyclin B and trigger mitosis. We have recently demonstrated that p-CDC25B-Ser351 is located at the centrosomes of mouse oocytes and contributes to the release of mouse oocytes from prophase I arrest. But much less is known about CDC25B function at the centrosome in two-cell stage mouse embryos. Here we investigate the effect of CDC25B regulating the microtubules nucleation. Microinjection of anti-CDC25B antibody caused aberrant microtubule nucleation...

A novel method for repair of vascular disease, mechanical damage, and tissue rebuilding is urgently required. Vascular endothelial cells (VECs) play an essential role in vascular rebuilding and vasotransplantation. In the present study, human gingival fibroblasts (HGFs) were cultured and induced into endothelial-like cells in vitro in order to confirm that HGFs with stem cell properties possessed the potential for differentiation into endothelial-like cells. The epithelium was extracted from normal human gingiva consisting of epithelium and connective tissue, which was isolated from patients...

Regeneration of lost organs involves complex processes, including host defense from infection and rebuilding of lost tissues. We previously reported that Xenopus neuronal pentraxin I (xNP1) is expressed preferentially in regenerating Xenopus laevis tadpole tails. To evaluate xNP1 function in tail regeneration, and also in tail development, we analyzed xNP1 expression in tailbud embryos and regenerating/healing tails following tail amputation in the 'regeneration' period, as well as in the 'refractory' period, when tadpoles lose their tail regenerative ability...

In this study, we verified nuclear transport activity of an artificial nuclear localization signal (aNLS) in medaka fish (Oryzias latipes). We generated a transgenic medaka strain expresses the aNLS tagged enhanced green fluorescent protein (EGFP) driven by a medaka beta-actin promoter. The aNLS-EGFP was accumulated in the nuclei of somatic tissues and yolk nuclei of oocytes, but undetectable in the spermatozoa. The fluorescent signal was observed from immediately after fertilization by a maternal contribution...

Follicular atresia, a common process present in all mammals, involves apoptotic and autophagic cell death. However, the participation of paraptosis, a type of caspase-independent cell death, during follicular atresia is unknown. This study found swollen endoplasmic reticulum in the granulosa cells of adult Wistar rats. Calnexin was used as a marker of the endoplasmic reticulum at the ultrastructural and optical levels. The cells with swelling of the endoplasmic reticulum were negative to the TUNEL assay and active caspase-3 immunodetection, indicating that this swelling is not part of any apoptotic or autophagic process...
