Adult hippocampal neurogenesis contributes to the hippocampal circuit's role in cognitive functioning. New neurons are generated from hippocampal neural stem cells (NSCs) throughout life, but their generation is substantially diminished in aged animals due to a decrease in NSC proliferation. Because acetylcholine (ACh) is an important neurotransmitter(More)
In the retina, both neurons and glia differentiate from a common progenitor population. CD44 cell surface antigen is a hyaluronic acid receptor expressed on mature Müller glial cells. We found that in the developing mouse retina, expression of CD44 was transiently observed at or around birth in a subpopulation of c-kit-positive retinal progenitor cells.(More)
Adult hippocampal neural stem cells can be activated by hippocampal neural activities. When focal cerebral ischemia, known as middle cerebral artery occlusion (MCAO), occurs, neural stem cells are activated to promote their proliferation. However, the mechanism by which these cells are activated is still unclear. Here, we indicate the involvement of(More)
This paper discusses the internationalization of the X Window System developed by the MIT X consortium. The main purpose is to enable X Window System Release 4 (X11R4) and earlier versions to support Asian languages, primarily Japanese, Chinese, and Korean. Unlike English and other European-based languages, Asian languages involve idiographic character(More)
5'TG3'-interacting factors (TGIFs) function as transcriptional repressors. Defects in TGIFs cause severe abnormalities in the developing brain and face. We found that Tgif2 was highly expressed in the mouse retina at early stages of development and examined its role in retinal development. Knockdown of Tgif2 in retinal explants at E14 using shRNA (sh-Tgif2)(More)
To analyze cell lineage-specific transitions in global transcriptional and epigenetic changes during retinogenesis, we purified retinal cells from normal mice during postnatal development into two fractions, namely, photoreceptors and other retinal cells, based on Cd73 expression, and performed RNA sequencing and ChIP sequencing of H3K27me3 and H3K4me3.(More)
PURPOSE We previously found that Kcnj10, an inwardly-rectifying potassium channel, is a gene expressed in c-kit-positive retinal progenitor cells on P1. The shRNA-mediated screening of the functions of the genes for retinal development in retinal explant culture suggested a role for Kcnj10 in the differentiation of 23Müller glia. In the present study, we(More)
Bone morphogenetic protein (BMP) plays pivotal roles in early retinal development. However, its roles in the late phase of retinal development remain unclear. We found that BMP receptors and ligands were expressed in the postnatal mouse retina. Furthermore, immunostaining revealed that phosphorylated Smads were enriched in various cells types in the inner(More)
The layered multilingual input/output(I/O) sytems we designed, based on typological studies of major-language writing conventions, unifies common features of such conventions to enable international and local utilization. The internationalization layer input module converts keystroke sequences to phonograms and ideograms. The corresponding output module(More)
