The efficiency of spermatogenesis and the support capacity of Sertoli cells in Characiformes
(2017-11-01)
This stereological analysis of the types of germ cells and the number of Sertoli cells per cyst in Astyanax altiparanae testes during spermatogenesis is the first such report in Characiformes. Testes of 25 male A. altiparanae ...
Interstitial and Langerhans' dendritic cells in chronic periodontitis and gingivitis
(Sociedade Brasileira de Pesquisa Odontológica, 2008)
The aim of the present study was to compare quantitatively the distribution of dendritic cell subpopulations in chronic periodontitis and gingivitis. Fourteen biopsies from patients with chronic periodontitis and fifteen ...
Human mesenchymal stromal cells in adhesion to cell-derived extracellular matrix and titanium: Comparative kinome profile analysis
(2019-03-01)
The extracellular matrix (ECM) physically supports cells and influences stem cell behaviour, modulating kinase-mediated signalling cascades. Cell-derived ECMs have emerged in bone regeneration as they reproduce physiological ...
Effect of air-powder system on titanium surface on fibroblast adhesion and morphology.
(2003-08-07)
PURPOSE: To evaluate the number and morphology of fibroblasts grown on machined titanium healing abutments treated with an airpowder system. MATERIALS AND METHODS: Twenty-six abutments were assigned to two experimental ...
Implant surface features as key role on cell behavior
(2022-01-01)
It has been recognized that physical and chemical properties of biomaterial surfaces mediate the quality of extracellular matrix (ECM) that may affect cell behaviors. In nature, ECM is a heterogeneous three-dimensional ...
Normal skin of HIV-infected individuals contains increased numbers of dermal CD8 T cells and normal numbers of Langerhans cells
(Associação Brasileira de Divulgação Científica, 2004)
Immunophenotypic characterization and distribution of dendritic cells in odontogenic cystic lesions
(Wiley-blackwellHobokenEUA, 2013)
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 ...
