Electrospun core-shell nanofibers with encapsulated enamel matrix derivative for guided periodontal tissue regeneration.

The osteogenic effect of a composite electrospun core-shell nanofiber membrane encapsulated with Emdogain (EMD) was evaluated. The membrane was developed through coaxial electrospinning using polycaprolactone as the shell and polyethylene glycol as the core. The effects of the membrane on the osteogenic differentiation of periodontal ligament stem cells (PDLSCs) were examined using Alizarin Red S staining and qRT-PCR.
