Do you remember the alarm about the cancer risks of CRISPR? According to a study published in Cell Stem Cell by Italian researchers, the DNA-damage response is not such a big problem in edited cells. At least not in hematopoietic stem cells edited with highly specific nucleases. Continue reading
Single-gender worlds will remain a sci-fi fantasy. Gay and lesbian couples won’t become parents this way for the foreseeable future. This kind of manipulation is just too risky for humans. But unisexually reproducing mice are an impressive accomplishment, and CRISPR stands out again as a powerful research tool, opening up brand new possibilities for the study of genomic imprinting. For further details, please see the STAT News article about the Cell Stem Cell paper by Zhi-Kun Li.
There is hardly any day without CRISPR news. February starts with researchers correcting abnormalities associated with Duchenne muscular dystrophy (Science Advances) and performing allele-specific editing in blind mice (bioRxiv, forthcoming in The CRISPR Journal). A repechage from January also: how to get pluripotent stem cells by CRISPRing just one gene (Cell Stem Cell).
