Mouse Sp7 encodes osterix (OSX), a zinc-finger transcription factor that is essential for osteoblast lineage commitment and maturation downstream of BMP and Wnt/β-catenin signaling. OSX coordinates transcriptional programs controlling extracellular matrix deposition and mineralization, including regulation of genes such as Bglap, Col1a1, and Alpl. In bone development and remodeling, Sp7 activity integrates cues from osteogenic progenitors to drive differentiation while modulating interactions with RUNX2-dependent pathways. Dysregulated Sp7/OSX function is linked to impaired ossification and skeletal phenotypes, making it relevant for studies of bone biology, fracture repair, and osteogenesis-related disorders.
OSX Double Nickase Plasmid (m) consists of a matched pair of plasmids engineered for high-specificity editing of the Sp7 locus in mouse cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within Sp7. When directed to adjacent sites on opposite DNA strands, the two nickases generate offset single-strand nicks that together produce a staggered double-strand break, requiring coordinated on-target activity from both guides. The resulting DNA break is resolved by endogenous cellular repair pathways, most commonly through non-homologous end joining (NHEJ), leading to insertions or deletions that disrupt Sp7 function. By requiring dual sgRNA engagement at the target locus, the double nicking approach enhances editing specificity and provides a complementary CRISPR strategy for applications where additional control over targeting precision is desired.
To support efficient identification of edited cells, one plasmid encodes GFP for fluorescent visualization of transfected populations, while the companion plasmid carries a puromycin resistance gene for antibiotic selection. Together, these features support efficient enrichment of co-transfected populations and simplify the validation of Sp7-disrupted clones.
