FGF7 encodes fibroblast growth factor 7 (FGF-7, keratinocyte growth factor), a paracrine ligand that primarily signals through FGFR2b to regulate epithelial cell proliferation, survival, migration, and differentiation. FGF-7 activity engages canonical receptor tyrosine kinase pathways including RAS–MAPK/ERK, PI3K–AKT, and PLCγ/PKC, shaping tissue repair programs and epithelial–mesenchymal communication. Dysregulated FGF7–FGFR2b signaling has been implicated in abnormal epithelial remodeling and inflammatory microenvironments, and is frequently studied in the context of oncogenic epithelial growth control and stromal–tumor crosstalk. In vitro, FGF7 perturbation is used to interrogate barrier function, wound-healing responses, and growth factor dependency across epithelial lineages.
FGF-7 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the FGF7 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within FGF7. 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 FGF7 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 FGF7-disrupted clones.
