          Abstract

          Resumen El esmalte dental, tejido más duro del cuerpo humano, es formado por medio de la diferenciación de células epiteliales conocidas como ameloblastos. Recientemente, las células epiteliales dentales de incisivo de rata han sido utilizadas como modelo celular de eventos fisiopatológicos durante la formación del esmalte dental. Sin embargo, en función de los eventos estudiados es meritorio comprender su comportamiento, particularmente cuando la concentración del Suero Fetal Bovino (SFB) varia. El propósito de este trabajo es evaluar el impacto de la concentración del SFB sobre el crecimiento, proliferación y supervivencia de las células epiteliales dentales. Células epiteliales dentales fueron cultivadas en DMEM/F12, en presencia y ausencia de SFB. Observaciones morfológicas e inmunohistoquímicos de la actina, vimentina y fibronectina fueron realizados. Los resultados permitieron constatar que la ausencia de SFB afectó negativamente la proliferación de las células epiteliales dentales, pero mantuvo una expresión óptima de la actina y vimentina. Se identificó una alteración en la expresión de la fibronectina en las células tratadas en ausencia de SFB. En conclusión, la carencia de SFB disminuyo drásticamente la supervivencia, proliferación y expresión de la fibronectina en las células epiteliales dentales de rata.

          Abstract Dental enamel, the hardest tissue in the human body is formed by the differentiation of epithelial cells known as ameloblasts. Recently rat incisor dental epithelial cells have been used as a cellular model of pathophysiological events during tooth enamel formation. However depending on the events studied, it is necessary to understand the behavior of these cells, particularly when the concentration of Bovine Fetal Serum (FBS) varies. The purpose of this work is to evaluate the impact of FBS concentration on the growth, proliferation, and survival of dental epithelial cells. Dental epithelial cells were cultured in DMEM/F12 culture medium in the absence and presence of 10% FBS. Morphological and immunohistochemical observations of actin, vimentin, and fibronectin were performed. The results confirm that the absence of FBS negatively affected the proliferation of dental epithelial cells but maintained an optimal expression of actin and vimentin. An alteration in the expression of fibronectin in the cells treated in the absence of FBS was identified. In conclusion, the lack of FBS dramatically decreased the survival, proliferation, and expression of fibronectin in rat dental epithelial cells.

          Optimization of chemically defined cell culture media--replacing fetal bovine serum in mammalian in vitro methods.

          Quality assurance is becoming increasingly important. Good laboratory practice (GLP) and good manufacturing practice (GMP) are now established standards. The biomedical field aims at an increasing reliance on the use of in vitro methods. Cell and tissue culture methods are generally fast, cheap, reproducible and reduce the use of experimental animals. Good cell culture practice (GCCP) is an attempt to develop a common standard for in vitro methods. The implementation of the use of chemically defined media is part of the GCCP. This will decrease the dependence on animal serum, a supplement with an undefined and variable composition. Defined media supplements are commercially available for some cell types. However, information on the formulation by the companies is often limited and such supplements can therefore not be regarded as completely defined. The development of defined media is difficult and often takes place in isolation. A workshop was organised in 2009 in Copenhagen to discuss strategies to improve the development and use of serum-free defined media. In this report, the results from the meeting are discussed and the formulation of a basic serum-free medium is suggested. Furthermore, recommendations are provided to improve information exchange on newly developed serum-free media. Copyright 2010 Elsevier Ltd. All rights reserved.

              Dynamic regulation of the structure and functions of integrin adhesions.

              Integrin-mediated cell adhesions to the extracellular matrix (ECM) contribute to tissue morphogenesis and coherence and provide cells with vital environmental cues. These apparently static structures display remarkable plasticity and dynamic properties: they exist in multiple, interconvertible forms that are constantly remodeled in response to changes in ECM properties, cytoskeletal organization, cell migration, and signaling processes. Thus, integrin-mediated environmental sensing enables cells to adapt to chemical and physical properties of the surrounding matrix by modulating their proliferation, differentiation, and survival. This intriguing interplay between the apparently robust structure of matrix adhesions and their highly dynamic properties is the focus of this article. Copyright © 2013 Elsevier Inc.
