Humans4
- It is estimated that up to 90% of cancers in humans originate in epithelial tissue, and the cells within such tumors are known to survive and divide even when they are no longer attached to the extracellular matrix. (elifesciences.org)
- There are now two ways to create new mammalian life, including humans. (cbc-network.org)

Genomic2
- BML mutations thus result in defects in DNA repair and genomic instability in the somatic cells, predisposing the patients to cancer development. (medscape.com)
- The overall result of the genomic instability in the proliferating cells is a high risk of malignancy, reduced fertility or infertility, B- and T-cell immunodeficiencies, and cutaneous manifestations, including photosensitivity, poikiloderma, and telangiectatic erythema. (medscape.com)
Physiologic1

Membrane1
- Following attachment to the host cell membrane, entry of the viral nucleic acid was thought to occur one of two ways: via the formation of a pore in the plasma membrane through which the RNA is then "injected" into the host cell cytoplasm, or via virus uptake by receptor-mediated endocytosis. (wikipedia.org)
Manipulation2
- Here, we establish a method to enable clonal isolation, selection, and expansion of properly edited cells, using OptoElectroPositioning technology for single-cell manipulation on a nanofluidic device. (nature.com)
- Therefore, the development of a method that allows screening of edited cells and minimizes cell manipulation and hands-on culturing would constitute a significant addition to the current genome engineering toolbox. (nature.com)
