Neurons response in the BDNF gradient and BDNF uniform microfluidic chip. (a) Population view of the neurons in the BDNF gradient microfluidic chip. From ① to ④, the concentration of BDNF concentration is increased, cell numbers increased too. (b) The number of neurons in different regions of BDNF gradient chip. (c) The direction of axon in the gradient microfluidic chip. Most of axons towards the high concentration gradient. (d) The direction of axon in the BDNF uniform microfluidic chip.
