Cas9 Stable Cell Line - MC3T3-E1 Subclone 14

The MC3T3-E1 subclone 14 cell line is an osteogenic progenitor mouse cell line derived from the skull of newborn mice. It is a well-established in vitro model for studying osteoblast differentiation, bone formation, and mineralization. This subclone exhibits high alkaline phosphatase activity and strong mineralization capacity under osteogenic culture conditions. The Cas9 Stable Cell Line - MC3T3-E1 Subclone 14 is a genetically engineered variant in which the CRISPR-associated protein 9 (Cas9) endonuclease is stably integrated into the genome. This modification allows for precise, efficient, and programmable genome editing without transient transfection, providing a stable platform for gene knockout, knock-in, and functional genomics studies. This cell line maintains stable Cas9 expression during passage culture and retains its unique osteogenic differentiation potential, making it ideal for longitudinal studies in bone biology.

The Cas9 Stable Cell Line - MC3T3-E1 Subclone 14 has significantly accelerated research on bone development and diseases. Researchers have used this cell line to study gene function in osteogenic processes by constructing targeted mutations in key regulatory factors such as the Runx2, Osterix, and BMP signaling pathways. Its applications extend to osteoporosis drug screening, where gene-edited clones can help evaluate treatment efficacy by mimicking disease-related mutations. Stable Cas9 expression also facilitates high-throughput CRISPR screening to identify novel genes involved in mineralization, matrix deposition, or osteoclast signaling crosstalk. Furthermore, this cell line can be used to study the mechanisms of bone metastasis in cancer research, allowing for precise editing of oncogenes/tumor suppressor genes in an osteogenic environment.
