Artificial stem cell niches

Matthias Lütolf

Stem cells are characterized by their dual ability to reproduce themselves (self-renew) and specialize (differentiate), yielding essentially unlimited numbers of daughter cells that can maintain and regenerate tissues. In contrast to their embryonic counte ...

Understanding engraftment of cultured epidermal stem cells

Nicolas Grasset

The epidermis and its appendages protect our body from environmental hazards. Cells generated in the basal layer continuously replace the terminally differentiated keratinocytes that are shed off the epidermal surface. Long-term renewal depends on specific ...

Enhancing the Reliability and Throughput of Neurosphere Culture on Hydrogel Microwell Arrays

Matthias Lütolf, Stefan Kobel, Monika Limacher

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 ...

Control of adult stem cell function by bioengineered artificial niches

Matthias Lütolf

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 ...

Stem cells and their niche: a matter of fate

Olaia Maria Naveiras Torres-Quiroga

Embryonic stem cells provide an in vitro model for developmental biologists to study cell fate decisions during ontogenesis, while somatic stem cells allow physiologists to understand tissue homeostasis in the adult. The behavior of stem cells is dependent ...

c-Myc controls the balance between hematopoietic stem cell self-renewal and differentiation

Anne Wilson

The activity of adult stem cells is essential to replenish mature cells constantly lost due to normal tissue turnover. By a poorly understood mechanism, stem cells are maintained through self-renewal while concomitantly producing differentiated progeny. He ...
