a Morphology of PLCL scaffold and PLCL scaffold modified with poly-l-lysine and HA by scanning electron microscopy (SB: scaffold blank; SP: PLCL-poly-l-lysine; S1L: PLCL-poly-l-lysine/HA-PLCL-poly-l-lysine). b Global structure of the multi-layer braided scaffold. The six different constitutive layers, made of 16 fibers/layer, are represented with different colors
