Muscle stem cells (MuSCs) have long been considered to be potential therapeutic vehicles for diseases of muscle such as muscular dystrophies. A recent study published in Cell Research by Fu et al. reveals that recapitulating in vitro the in vivo microenvironment of MuSCs that occurs during muscle regeneration might be a major step towards translation.
Killing cancer cells can have undesired side effects. Upon drug treatment, drug-sensitive cancer cells secrete an array of growth factors that stimulate the proliferation and dissemination of drug-resistant cells in the population.
The role neutrophils play in cancer is a matter of debate as both pro- and anti-tumor functions have been documented. In a recent publication in Nature, Coffelt et al. identify a new mechanism where neutrophils and T cells cooperate to generate metastasis-supporting immune suppression.
Mosaic mutations and off-target effects caused by CRISPR/Cas9 have led to concerns about the efficiency and specificity of this new technique in non-human primates and other large animals. Here we discuss recent findings from primate embryos, with a focus on the technical issues CRISPR/Cas9 faces before producing non-human primate models of human diseases.
The extent to which DNA repair machinery facilitates gene activation remains poorly appreciated. A new study published in Cell Research reports a novel function of H2AX, a substrate of ATM and known DNA damage marker, in transcriptional initiation.
