The putative existence of a cancer stem cell niche consisting of bi-directional stromal and stem cell secreting factors that trigger cancer stem cell growth and proliferation has been hypothesized in the nervous and hematopoietic systems. In light of this theory, it has been proposed that embryonic stem cell microenvironments, upon interactions with cancer(More)
BACKGROUND High proliferative and differentiation capacity renders embryonic stem cells (ESCs) a promising cell source for tissue engineering and cell-based therapies. Harnessing their potential, however, requires well-designed, efficient and reproducible expansion and differentiation protocols as well as avoiding hazardous by-products, such as teratoma(More)
Understanding the genetic and molecular mechanisms of ovarian cancer has been the focus of research efforts working toward the greater goal of improving cancer therapy for patients with residual disease after initial treatment with conventional surgery and neoadjuvant chemotherapy. The focus of this review will be centered on new therapeutic strategies(More)
Derivation of human embryonic stem cell lines has been a remarkable scientific achievement during the last decade. Human embryonic stem cells are regarded as an unlimited cell source for replacement therapy in regenerative medicine. Clearly, the scientific community requires proper derivation, characterization, and registration with the purpose of making(More)
Differentiation therapy pursues the discovery of novel molecules to transform cancer progression into less aggressive phenotypes by mechanisms involving enforced cell transdifferentiation. In this study, we examined the identification of transdifferentiating adipogenic programs in human cancer cell lines (HCCLs). Our findings showed that specific(More)
The stem cell field owes a great deal to the previous work conducted by embryologists and researchers devoted to reproductive medicine. The time is coming when this emerging field will pay off in the reproductive sciences by offering new avenues of understanding gametogenesis and early embryonic development. Human embryonic stem cells are pluripotent cells(More)
OBJECTIVE Compare the efficiency of two vitrification methods for single-blastomere cryopreservation with mouse or human embryos. DESIGN Experimental prospective controlled study. SETTING Research center. PATIENT(S) Human Blastomeres were obtained after biopsy. INTERVENTION(S) Mouse blastomeres were obtained after diluting the zona pellucida of(More)
UNLABELLED Enforced cell transdifferentiation of human cancer cells is a promising alternative to conventional chemotherapy. We previously identified albumin-associated lipid- and, more specifically, saturated fatty acid-induced transdifferentiation programs in human cancer cells (HCCLs). In this study, we further characterized the adipocyte-like cells,(More)
