چکیده
In this issue of Molecular Pharmacology, Meyn et al. (p. 1320) provide the results of the first comprehensive investigation of the expression pattern of the Src family of nonreceptor tyrosine kinases (SFK) in mouse embryonic stem (ES) cells. They found that self-renewing ES cells express seven of the eight mammalian SFK members and that some undergo distinct expression changes during early differentiation events. One of the most dramatic changes was in Hck transcript levels, which decreased almost 30-fold during the first 3 days of embryoid body formation, a culture system model of early embryogenesis and differentiation. Other SFKs, such as Fyn and Src, remain present and active as ES cells differentiate. Of particular interest was the observation that ES cell self-renewal or differentiation can be manipulated through the selective pharmacological inhibition of SFK members. This information should help in the expanding efforts to exploit ES cells for basic and clinical purposes.

متن کاملActive Ageing: Live longer and prosper Realising the benefits of extended healthy life expectancy and ‘disability compression’ in Europe
However, reducing the number of premature deaths and opening the way to active ageing (defined as continuing to live independently as an engaged member of society) is better seen as a success to be celebrated, not a problem to be contained. Loss of a productive social role because of disabling diseases or cognitive decline is not an inevitable consequence of reaching 65, 75 or 80 years of age. ...
متن کاملLive foods in the feeding of aquarium fish larvae
At reproduction centers, using live food is important, especially when it comes to the first feeding of aquarium fish larvae. Live foods commonly used in the aquarium aquaculture industry include rotifers in two sizes, small types with a size of 50-110 microns, and larger types with a size of 100-200 microns, Artemia, and copepods. Fish larvae in marine aquariums primarily consume copepod...
