Human PDGFB encodes platelet-derived growth factor subunit B (PDGF-B), a secreted dimeric growth factor that signals primarily through PDGFRβ to regulate pericyte recruitment, vascular maturation, and mesenchymal cell proliferation and migration. PDGF-B activates canonical receptor tyrosine kinase pathways including PI3K–AKT, RAS–MAPK, and PLCγ–PKC, linking extracellular cues to cytoskeletal remodeling and survival programs. In normal physiology, PDGF-B is central to wound repair, extracellular matrix dynamics, and tissue remodeling in stromal compartments. Dysregulated PDGFB/PDGFR signaling is implicated in aberrant angiogenesis, fibrotic remodeling, and oncogenic stromal interactions, making PDGF-B a frequent focus in mechanistic studies of microenvironment-driven disease processes.
PDGF-B Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the PDGFB locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within PDGFB. 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 PDGFB 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 PDGFB-disrupted clones.
