Abstract Osteoarthritis (OA) is an inflammatory and progressive joint disease characterized by angiogenesis‐mediated sustained, chronic, low‐grade synovitis. Anti‐angiogenesis emerging as a strategy for attenuating OA progression, but often compromised poor targeted drug delivery immune clearance. Recent studies have identified macrophages formed “protective barrier” in the lining layer (LL) of synovium, which blocked communication cavity sublining (SL) synovium. Inspired natural mimicry, macrophage membrane‐camouflaged explored to avoid Based on single cell RNA sequencing, CD34 + synovial cells are “sentinel cells” synovium angiogenesis. Consequently, antibody‐modified membrane constructed target new Hence, biomimetic multi‐layered nanoparticle (NP) developed that incorporates axitinib‐loaded poly(lactic‐co‐glycolic) acid (PLGA) with antibody modified (Atb@NP@Raw@CD34) specifically deliver axitinib (Atb) SL sustain inhibiting angiogenesis without elimination. It found Atb@NP@Raw@CD34 can pass through “barrier”, targeting cells, continuously releasing Atb anti‐angiogenesis Furthermore, vivo data demonstrated attenuate degeneration In conclusion, local injection presents promising approach clinically impeding progression.
