A necessidade atual em se continuar a pesquisar com células-tronco embrionárias
Embryonic stem cells are pluripotent and able to generate all cell types of the body, being the most promising cells to the study for regenerative medicine. Following the differentiation path, there are adult stem cells, ...
Multiple cytogenetic clones in a basal cell carcinoma
Chromosome analysis of short-term culture of a basal cell carcinoma showed five clonal chromosome abnormalities, t(9;14)(q12 or q13;p11), del(1)(q23 or q25), trisomy 5, trisomy 7, and monosomy X. In addition, several ...

Morpho-functional study of human luteal cell subpopulations
(Oxford University Press, 1994)
It has been reported that the mammalian corpus luteum is composed mainly of two subpopulations of luteal cells (large and small) of different morphology and function. The aims of this study were first to characterize ...
Lack of genotoxicity of formocresol, paramonochlorophenol, and calcium hydroxide on mammalian cells by comet assay
Formocresol, paramonochlorophenol, and calcium hydroxide are widely used in dentistry because of their antibacterial activities in root canal disinfection. However, the results of genotoxicity studies using these materials ...
Translocation (4;14) and concomitant inv(14) in a basal cell carcinoma
Chromosome analysis of short-term cultures from a basal cell carcinoma was performed. The analyzed karyotypes showed a pseudodiploid clone characterized by a der(4)t(4;14)(p14;p11) and a concomitant inversion of the same ...
Renal interstitial foam cells are macrophages
Immunohistochemical studies on renal biopsies from eight patients with various types of glomerulonephritis showed that the interstitial foam cells belonged to the monocyte-macrophage lineage. There was a strong association ...
