We report improved whole-genome shotgun sequences for the genomes of indica and japonica rice, both with multimegabase contiguity, or almost 1,000-fold improvement over the drafts of 2002. Tested against a nonredundant collection of 19,079 full-length cDNAs, 97.7% of the genes are aligned, without fragmentation, to the mapped super-scaffolds of one or the(More)
BACKGROUND Amnestic mild cognitive impairment (aMCI) is thought to be a transitional stage between normal aging and the development of Alzheimer's disease (AD). Recent studies have suggested that the inhalational anesthetic isoflurane can induce caspase activation and apoptosis, increase aggregates of β-amyloid (Aβ) levels, and enhance Aβ aggregation. The(More)
Much research has indicated that the mitogen-activated protein kinase (MAPK)-cAMP response element-binding protein (CREB) signal transduction pathway is involved in the pathophysiological mechanism of depression. But as to the question of which MAPKs are more relevant to stress effects, there is no definite answer. In the present study, 32 male(More)
Interactions between the extracellular matrix (ECM) and epithelial cells are necessary for the proper organization and function of the epithelium. In the present study, we show that human eccrine sweat gland epithelial cells cultured in matrigel, a representation of ECM components, constitute a good model for studying three-dimensional reconstruction, wound(More)
Victims with extensive and deep burns are unable to regenerate eccrine sweat glands. Combining of stem cells and biomimetic ECM to generate cell-based 3D tissues is showing promise for tissue repair and regeneration. We co-cultured BrdU-labeled bone marrow-derived mesenchymal stem cells (BM-MSCs) and eccrine sweat gland cells in Matrigel for 2 weeks in(More)
The rat whisker hair follicle (HF) is a model for studying the reconstruction of the HF or dermal papilla (DP), and involves the Wnt/β-catenin signaling pathway, which is a key pathway in HF development and HF cycling after birth. It has been reported that Wnt/catenin signaling plays an indispensable role in human or rat pelages development and postnatal(More)
Mesenchymal stem cells (MSCs) are multipotent cells with the capacity for self-renewal and differentiation and have a broad tissue distribution. These characteristics make them candidate cells for wound healing and regeneration in a variety of disorders. Endogenous MSCs or exogenously delivered MSCs can traffic and migrate to injured tissue and participate(More)
We have examined the changes of keratins and alpha-SMA at various time points in order to investigate the development and differentiation of eccrine sweat gland cells during the course of three-dimensional (3D) reconstitution. Mixtures of eccrine sweat gland cells and Matrigel were injected subcutaneously into the inguinal regions of nude mice. At 1, 2, 4,(More)
Increasing evidence indicates that maintenance of cell polarity plays a pivotal role in the regulation of glandular homeostasis and function. We examine the markers for polarity at different time points to investigate the formation of cell polarity during 3D reconstitution of eccrine sweat glands. Mixtures of eccrine sweat gland cells and Matrigel were(More)
Although mammals are notoriously poor at regeneration compared with many lower-order species, the hair follicle, particular to mammals, is capable of regeneration following partial amputation. The detailed internal mechanism of this phenomenon is still unclear. Development and regrowth of the hair follicle depends on dermal-epidermal interaction within the(More)
