Future cell-based therapies such as tissue engineering will benefit from a source of autologous pluripotent stem cells. For mesodermal tissue engineering, one such source of cells is the bone marrow stroma. The bone marrow compartment contains several cell populations, including mesenchymal stem cells (MSCs) that are capable of differentiating into(More)
Much of the work conducted on adult stem cells has focused on mesenchymal stem cells (MSCs) found within the bone marrow stroma. Adipose tissue, like bone marrow, is derived from the embryonic mesenchyme and contains a stroma that is easily isolated. Preliminary studies have recently identified a putative stem cell population within the adipose stromal(More)
Rice dwarf virus (RDV), the causal agent of rice dwarf disease, is a member of the genus Phytoreovirus in the family Reoviridae. RDV is a double-shelled virus with a molecular mass of approximately 70 million Dalton. This virus is widely prevalent and is one of the viruses that cause the most economic damage in many Asian countries. The atomic structure of(More)
The rice species Oryza sativa is considered to be a model plant because of its small genome size, extensive genetic map, relative ease of transformation and synteny with other cereal crops. Here we report the essentially complete sequence of chromosome 1, the longest chromosome in the rice genome. We summarize characteristics of the chromosome structure and(More)
Stem cell based therapies for the repair and regeneration of various tissues and organs offer a paradigm shift that may provide alternative therapeutic solutions for a number of diseases. Although embryonic stem cells and induced pluripotent stem cells are theoretically highly beneficial, there are various limitations to their use imposed by cell(More)
BACKGROUND AIMS Transplantation of mesenchymal stromal cells (MSC) derived from bone marrow (BM) or adipose tissue is expected to become a cell therapy for stroke. The present study compared the therapeutic potential of adipose-derived stem cells (ASC) with that of BM-derived stem cells (BMSC) in a murine stroke model. METHODS ASC and BMSC were isolated(More)
The potential use of stem cell-based therapies for the repair and regeneration of various tissues and organs offers a paradigm shift that may provide alternative therapeutic solutions for a number of diseases. The use of either embryonic stem cells (ESCs) or induced pluripotent stem cells in clinical situations is limited due to cell regulations and to(More)
The use of undifferentiated cells for cell-based tissue engineering and regeneration strategies represents a promising approach for skeletal muscle repair. For such strategies to succeed, a readily available source of myogenic precursor cells must be identified. We have previously shown that cells isolated from raw human lipoaspirates, called processed(More)
BACKGROUND & AIMS The role of two forms of cyclooxygenase (COX-1 and COX-2) in gastric mucosal lesions is not well understood. The regulation of both forms of COX and the effect of COX-2 on the repair process of gastric mucosal lesions in mice were investigated. METHODS Gastric mucosal erosions and ulcers were induced experimentally in mice. The level of(More)
A number of surgical techniques have been developed to promote periodontal tissue regeneration. Bone marrow-derived stem cells have also been shown to promote periodontal tissue regeneration. In this study, we sought to determine whether adipose-derived stem cells (ASCs) can promote periodontal tissue regeneration as well. ASCs were isolated from a Wistar(More)
