Resumen
El carcinoma de células renales (CCR) constituye el cáncer urológico más letal, representa el 2-3% de todos
los tumores y es la lesión sólida más frecuente en el riñón adulto. Dentro del grupo heterogéneo que engloba el
CCR un 70-80% de éstos incluye el Carcinoma Renal de Células Claras (CRCC). Reciente evidencia sugiere
que muchas enfermedades malignas son impulsadas por un fracción celular que muestra propiedades de
células madre en las denominadas células madre cancerígenas (CSC). Para lograr la identificación de esta
subpoblación celular se ha desarrollado una metodología fenotípica alternativa basada en la formación de
esferas in vitro. En este estudio, cómo análisis preliminar, se seleccionaron varias líneas celulares de RCC
(Caki-2, Caki-1 y ACHN) y células renales de origen embrionario (HEK-293) fueron empleadas como linea
celular control. En ésta última mencionada, se formaron estructuras 3D exitosamente con aumento progresivo
de tamaño durante todo el tiempo de ensayo pero de las tres líneas tumorales renales ensayadas (Caki-1, Caki-
2 y ACHN), solo Caki-1 pudo formar esferas 3D estables, aunque sin crecimiento tridimensional a largo plazo.

Renal cell carcinoma (RCC) is the most lethal urological cancer, representing 2-3% of the total of tumours and is the most common solid injury in the adult kidney. Within the heterogeneous group that includes RCC, 70- 80% of these involve the Renal Carcinoma of Clear Cells (CRCC). Recent findings suggest that many malignancies are driven by a cellular compartment that displays stem cell properties called cancer stem cells (CSCs). To achieve the identification of this cellular subpopulation an alternative phenotypic methodology based on the formation of in vitro spheres has been developed. In this study, as a preliminary analysis, several RCC cell lines (Caki-2, Caki-1 and ACHN) were selected and the control was from embryonic kidney cells (HEK-293) were performed as a control cell line. HEK-293 cell line formed 3D structures successfully with progressive increase in size during the entire experimental time and what concerns to the three renal tumour lines tested (Caki-1, Caki-2 and ACHN), although only Caki-1 could form stable 3D spheres, it was without long-term threedimensional growth.
