From: Asymmetric Sensory-Motor Regeneration of Transected Peripheral Nerves Using Molecular Guidance Cues

Diffusion of PLGA microparticles loaded with NTF and BSA over a 30 day time period. At Day 1 there is a burst release followed by a gradient formation in the subsequent days. The top compartment represents PTN-MP release and BSA-MP release in the bottom compartment. Arrow heads indicate the approximate position of nerve regeneration.
