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 optima 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.
