    Cell division is the key to the development of multicellular organisms (including humans), and the dysregulation of this process is the basis of many diseases, including the development and spread of cancer


    The first author of the IRB Barcelona Microtubule Tissue Laboratory, Ricardo Viais, and his leader Jens Lüders, have determined that the protein complex augmin is a key element of stem cell division during embryonic brain development


    In the developing brain of a mouse embryo, when the augmin complex is inactivated, brain development stops, and the embryo dies before birth


    By deleting the p53 gene, cell death caused by the loss of augmin can be prevented


    "Our research may have a profound effect on the proliferation of stem cells during brain development, because cell division is also crucial for cancer cell proliferation, colonization in tissues, and tumor formation



    Augmin deficiency in neural stem cells causes p53-dependent apoptosis and aborts brain development
