Embryonic stem (ES) cells represent a unique cellular model to recapitulate in vitro early steps of embryonic development and an unlimited cellular source in therapy for many diseases, as well as targets for drug discovery and toxicology screens. Although ...
Hair follicles are cutaneous structures characteristic of mammals. These sensitive organs cycle and contain multipotent epithelial stem cells which are implicated in hair growth and hair cycle. A single whisker follicle of the rat hosts up to 1500 stem cel ...
Continuous turnover of epithelia is ensured by the extensive self-renewal capacity of tissue-specific stem cells. Similarly, epithelial tumour maintenance relies on cancer stem cells (CSCs), which co-opt stem cell properties. For most tumours, the cellular ...
Blood stem cells, also termed hematopoietic stem cells (HSC), are used clinically to treat numerous blood cancers. However, due to the low numbers of HSCs that can be isolated from the bone marrow of donors, broad application of this treatment is severely ...

Stem cells are characterized by their dual ability to self- renew and differentiate, yielding essentially unlimited numbers of progeny that can replenish tissues with either high turnover such as blood and skin or contribute to the regeneration of organs w ...
The neurosphere assay is the standard retrospective assay to test the self-renewal capability and multipotency of neural stem cells (NSC) in vitro. However, it has recently become clear that not all neurospheres are derived from a NSC and that on conventio ...
The formation of scar tissue due to dedifferentiation of smooth muscle cells (SMCs) is one of the major issues faced when engineering bladder tissue. Furthermore, cell sources for regenerating the SMC layer are also limiting. Here we explore if human mesen ...
Adult stem cells reside in a specialized microenvironment, the niche, which controls their behavior. As mammary stem cells, and consequently their niches, are still poorly defined, we look at better-characterized adult mammalian stem cell niches in the hem ...
Adult stem cells represent only a minor proportion of a given tissue and are difficult to amplify in vitro without affecting their biological properties. To circumvent this problem, we used a transgenic/lentiviral based approach to isolate and characterize ...
The epithelial-mesenchymal transition (EMT) is a key developmental program that is often activated during cancer invasion and metastasis. We here report that the induction of an EMT in immortalized human mammary epithelial cells (HMLEs) results in the acqu ...
