Mouse artificial 'embryo' created from stem cells - BioNews


BioNews
The researchers had previously worked on a simpler structure of a mouse embryo consisting of two types of stem cells and a 3D jelly scaffold. In the new study – published in Nature Cell Biology – they used all three types of stem cells: embryonic stem ...

TCR signal strength controls the differentiation of CD4 - Science


Science
T cell differentiation into effector and memory T cell subsets is influenced by T cell receptor (TCR) signals. Snook et al. examine how TCR signals influence CD4+ T cell differentiation using a panel of cloned TCRs that recognize the same MHC II ...

Structure of Memes
Belgium

The main criticism that can be raised against the memetic approach is that memes are difficult to define. What are the elements or units that make up a meme? Does a meme correspond to a complete symphony, or to a symphonic movement, a melody, a musical phrase, or even a single note?
