According to the cancer stem cell hypothesis tumors are maintained by a cancer stem cell
population which is able to initiate and maintain tumors. Tumor‐initiating stem cells display …

The renal cell carcinomas (RCC) denote a diverse set of neoplasias with unique genetic and
histological features. The RCCs emanate from the renal tubule, a highly heterogeneous …

Cancer stem cells (CSCs), isolated in renal carcinomas, exhibit tumor-initiating capabilities
and pluripotency. No specific CSC markers have been identified so far; therefore, their …

The purpose of the present study was to search for the presence of a tumor‐initiating stem
cell population in renal carcinomas. Based on the recent identification of mesenchymal stem …

The term “cancer stem cell”(CSC) refers to a cancer cell with the following features:
clonogenic ability, the expression of stem cell markers, differentiation into cells of different …

In the present study, we tested the hypothesis that resident progenitor cells may contribute to
tumor vascularization and growth. CD133+ cells were isolated from 30 human renal …

Recently, several studies have investigated the presence of cancer stem cells in kidney
cancer, performed characterization, and compared their profile with the normal stem cell …

In recent years, cancer stem cells (CSCs)/tumor initiating cells (TICs) have been identified
inside different tumors. However, currently used anti-cancer therapies are mostly directed …

Renal cell carcinoma (RCC) is a major neoplasm with high incidence in western countries.
Tumors are heterogeneous and are composed of differentiated cancer cells, stromal cells …

There is evolving evidence for the so-called cancer stem cell (CSC) hypothesis, which holds
that intra-tumoral heterogeneity in urologic malignancies is hierarchical and that not all cells …
