Chitosan, a natural biopolymer derived from chitin, is considered a promising scaffold material for bone tissue engineering. The ability of chitosan to promote the osteogenic differentiation of dental pulp stromal/stem cells (DPSCs) is unknown. We have evaluated the potential of chitosan to induce the osteogenic differentiation of macaque DPSCs in(More)
The mouse has been used extensively as a model for radiobiological studies. In particular, the cellular compartments of the intestinal villi have been examined, in an effort to gain an understanding of the gastrointestinal disturbances which follow radiotherapy of the abdomen. The response of the blood vessels has been, however, largely neglected. This(More)
Disturbances of gastrointestinal function are an important limiting factor in radiotherapy of the abdominal and pelvic regions. The pathogenesis of radiation induced intestinal dysfunction is not completely understood, although the intestinal mucosa has been shown to respond to irradiation by a progressive reduction in villous size. Since blood vessels in(More)
The internal structure of the mouse jejunal villus was examined from apex to base in transverse serial sections. The villi were arbitrarily divided into apical (1-160 microns), middle (161-320 microns) and basal (321-480 microns) thirds. Histological and ultrastructural morphometry was performed on villous epithelium, stroma, blood vessels and lacteals at(More)
This study set out to compare the growth patterns and morphological characteristics of human fallopian tube epithelial cells isolated: (1) mechanically; and (2) enzymatically. Cells were cultured in medium supplemented with fetal bovine serum and antibiotics and their epithelial nature was established by immunocytochemistry for cytokeratins. Primary(More)
Crypts of Lieberkuhn are radiosensitive: the technique of crypt counting is an established method of assessing radiation induced changes in the small intestine. However, there has been little work done on the surface contours of the crypts, as they open into the intervillous cleft. The current paper describes the structure of control mouse crypt mouths as(More)
Objective: The purpose of this investigation was to determine the effect of chitosan on osteoclast cells by observing cell viability, bone resorption, and radical oxygen species (ROS) production. Methods: Osteoclast cells were obtained from the primary culture of bone marrow mouse. The osteoclast cells were identified by tartrate-resistant acid phosphatase(More)
In 1986, the National Nuclear Energy Agency (Batan) in Jakarta started the research and development for the setting up of a tissue bank (Batan Research Tissue Bank/BRTB) by preserving fresh amnion or fetal membranes by lyophilisation and then sterilising by gamma irradiation. During the period of 1990 and 2000, three more tissue banks were set up, i.e.,(More)
