Cas9 Stable Cell Line - Hs 865.Sk

The Hs 865.Sk-Cas9 stable cell line is a specialized human genetic model established by integrating the Cas9 nuclease into the human Hs 865.Sk cell line. Hs 865.Sk is a fibroblast-like cell line derived from normal human skin, providing a standardized model for studying human skin biology and wound healing. Unlike transformed cancer cell lines, these cells represent the physiological state of normal human fibroblasts, characterized by good adherence and stable growth in vitro. Constitutive expression of Cas9 in this cell line provides an efficient and reproducible platform for CRISPR-mediated gene editing, ensuring consistent editing capabilities across all cells. This stabilization system enables precise gene manipulation of normal human cell models, making it a powerful tool for functional genomics and exploring non-malignant tissue and cellular responses.

The primary applications of the Hs 865.Sk-Cas9 stable cell line are in the study of skin physiology, aging, and tissue repair mechanisms. Researchers utilize this system for CRISPR screening to identify genes involved in collagen synthesis, skin inflammation, and aging cellular pathways. The Hs 865.Sk-Cas9 strain is particularly well-suited for constructing gene-targeted knockout models associated with skin diseases, enabling scientists to study the molecular mechanisms of various skin conditions in a human context. Furthermore, it serves as a reliable platform for evaluating the toxicity of cosmetic ingredients and drugs to human skin and for studying the interactions between fibroblasts and other skin components. Its well-defined normal state and stable Cas9 expression make it an indispensable resource for basic dermatology research and the development of novel therapies for skin diseases.
