The intranasal use of bFGF nanoliposomes was explored for functional recovery in rodent cerebral ischemia model [13,33]; platelet-membrane-cloaked nanocarriers were used to delivery bFGF that promoted angiogenesis and neurogenesis and neurobehavioral recovery [34]; biodegradable polyglycolic acid sheets releasing bFGF was revealed to promote angiogenesis and activated NPCs in mice [16]. The gene discussed is FGF2; the disease is brain ischemia.
