Fig. 6From: Functional significance of CD105-positive cells in papillary renal cell carcinomaHanging drop assay of pRCC cell lines. Representative images of aggregates formed by tested cell lines in a hanging drop assay. The HKCSC cell line generated a homogeneous, compact 3D aggregate, while Caki-2, ACHN, and ASE remained loose and were bigger than the structure of HKCSCBack to article page
