What signals operate in the mammary niche?
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 hematopoietic system and the skin. We attempt to define the mammary stem cell niche functionally, based on the widely used mammary fat pad recon...
متن کاملBalancing signals in the intestinal niche
T he intestinal tract faces an enormous amount of internal and external stress stimuli on a daily basis. In order to cope with these stress factors and prevent potential damage, the entire epithelium is being replaced every five days. The inner layer of the intestine consists of a single epithelial layer that displays extrusions called “villi” and invaginations known as “crypts”. Regeneration a...
متن کاملDouble duty for mammary stem cell niche.
Low-temperature methane reactions Methane is a potential feedstock for more valuable products. The strong carbon-hydrogen bonds of methane can be activated by heterogeneous catalysts but often at temperatures that make it difficult to control reactions selectively. Liang et al. show that methane, adsorbed on the stoichiometric IrO 2 (110) under ultrahigh-vacuum conditions, reacts with exposed i...
متن کاملAt what time scale does the nervous system operate?
A novel statistical strategy, the spike jitter method, was developed to assess temporal structure in spike trains from neuronal ensembles. Its key feature is the introduction of a null hypothesis that assumes a uniform relative likelihood of observing a spike at one temporal location versus another within a small temporal window. We applied the method to simultaneously recorded motor cortical n...
متن کاملWhat influences youth to operate all-terrain vehicles safely?
The operation of all-terrain vehicles (ATVs) by youth has contributed to the incidence of serious and fatal injuries among children. This study explored factors related to the frequency with which youth wore a helmet and refrained from engaging in three risky driving behaviors (driving at risky speeds, on paved roads and on unfamiliar terrain) while operating an ATV. Youth (n = 248) aged 9-14 f...
