1. Dental pulp stem cells express proteins involved in the local invasiveness of odontogenic myxoma
Little is known about the histogenesis of the odontogenic myxoma (OM). Dental pulp stem cells could be candidate precursors of OM because both OM and the dental pulp share the same embryological origin: the dental papilla. For the purpose of comparing OM and stem cells, this study analyzed the expression of two proteins related to OM invasiveness (MMP-2 and

3. Testicular morphology and morphometry in mice chronically exposed to arsenic / Morfologia e morfometria testicular de camundongos adultos submetidos à exposição crônica ao arsenato
There is an increasing concern about the potentially harmful effects of several environmental pollutants, as for instance, the inorganic arsenic, one of the main pollutants of the water worldwide. The intoxication by arsenic can be acute or chronic, and lead to a variety of pathologies and impairment of male reproductive system. This work aimed to investigat

4. Obtenção de anticorpos para moleculas de expressão especifica em celulas natural Killer uterinas (NKu) de camundongos
During the pregnancy in the rodents a transient accumulation of natural killer (NK) cells 1s seen In the uterus. These cells found in the uterine environment express the surface antigen common to drculating NK (cNK) cells, but they do not show some cytokine receptors and do not trigger the cytoJytíc activity during normal pregnancy. Such a peculiar behavior

5. A espermiogenese em Boophilus microplus (Canestrini, 1887) (Acari:ixodidae) : aspectos estruturais e ultra-estruturais
The objective of this study was to describe the spermatogenesis of the cattle tick (Boophilus microplus) (Canestrini, 1887), based on histological, histochemical, morphologic and ultrastructural infromation. Spermatogenesis occurs in the testis of ticks which begin their blood repast. The gametic cell lineage is isolated in cysts. Spermiogenesis begins in th

6. Propagation of human parvovirus B19 in primary culture of erythroid lineage cells derived from fetal liver.
Erythroid lineage cells derived from fetal liver were demonstrated to be target cells for human parvovirus B19 infection. B19 virus antigen-positive serum was inoculated into primary cultures containing erythroid lineage cells enriched from fetal liver. The B19 virus antigen was detected on about 5% of cells in the culture by immunofluorescence staining, and

7. Isolation of a DEAD-family protein gene that encodes a murine homolog of Drosophila vasa and its specific expression in germ cell lineage.
In an effort to study the molecular basis of the determination processes of the mammalian germ cell lineage, we have tried to isolate a mouse gene homolog to vasa, which plays an essential role as a maternal determining factor for the formation of Drosophila germ cell precursors. By reverse transcriptase PCRs of mouse primordial germ cell cDNAs using family-

8. The postnatal development of the liver in a marsupial, Didelphis virginiana. 2. Electron microscopy.
The postnatal development of the liver has been examined with the electron microscope in 15 groups of young opossums. At birth, hepatic cells show little organization and large islands of haemopoietic elements occur between clusters of hepatic cells. Hepatocytes appear small and contain an abundance of granular endoplasmic reticulum. The cytoplasm is also ch

9. Segregation During Ascidian Embryogenesis of Egg Cytoplasmic Information for Tissue-Specific Enzyme Development
Cleavage-arrested embryos of the ascidian Ciona intestinalis were able to differentiate two tissue-specific enzymes—muscle acetylcholinesterase (EC 3.1.1.7) and brain pigment cell tyrosinase (EC 1.10.3.1). Cytochalasin B, colchicine, Colcemid, and podophyllotoxin were used as cleavage inhibitors at early embryonic stages up to the 64-cell stage. Only certa

10. Normal development and function of natural killer cells in CD3 epsilon delta 5/delta 5 mutant mice.
The CD3 epsilon polypeptide contributes to the cell surface display as well as to the signal transduction properties of the T-cell antigen receptor complex. Intriguingly, the distribution of CD3 epsilon is not restricted to T cells, since activated mouse, human, and avian natural killer (NK) cells do express intracytoplasmic CD3 epsilon polypeptides. CD3 eps

11. Cellular aging, destabilization, and cancer.
Three major characteristics of aging in animals are a slowdown of cell proliferation, an increase in residual bodies associated with age pigments, and a marked increase in the likelihood of neoplastic transformation. The 28 L subline of the NIH 3T3 line of mouse embryo fibroblasts exhibits all these characteristics when held at confluence for extended period

12. Attenuation of the self-renewal of transit-amplifying osteoblast progenitors in the murine bone marrow by 17β-estradiol
In agreement with evidence that estrogens slow the rate of bone remodeling by suppressing the production of both osteoclasts and osteoblasts, loss of estrogens leads to an increase in the number of osteoclast as well as early osteoblast progenitors (CFU-osteoblasts; CFU-OBs) in the murine bone marrow. Here we show that CFU-OBs are early transit-amplifying pr
