Background:

Retinal degenerative diseases cause irreversible vision loss due to retinal cell death.
Cell-replacement therapy using retinal progenitor cells (RPCs) is a potential treatment strategy.
Biodegradable polymer scaffolds are crucial for supporting transplanted retinal cells.

Purpose of the Study:

To design and fabricate a novel electrospun poly(ϵ-caprolactone) (PCL) scaffold for retinal cell transplantation.
To evaluate the scaffold's suitability for supporting retinal progenitor cell adhesion, proliferation, and differentiation in vitro.
To assess the scaffold's ability to facilitate RPC migration into host retinal tissue.

Main Methods:

Fabrication of an ultra-thin electrospun PCL scaffold with controlled microscale fiber diameters and porosity.
In vitro assessment of mouse RPC adhesion, proliferation, and differentiation on the PCL scaffold.
In vitro evaluation of RPC migration into mouse retinal explants cultured on the scaffold.

Main Results:

The electrospun PCL scaffold demonstrated microscale fiber diameters and appropriate porosity.
The scaffold supported robust proliferation, adhesion, and differentiation of mouse RPCs in vitro.
RPCs successfully migrated from the PCL scaffold into mouse retinal explants.

Conclusions:

The novel electrospun PCL scaffold is biocompatible and supports key cellular functions necessary for retinal regeneration.
PCL scaffolds show significant potential as substrates for cell transplantation in retinal regenerative research.
This study provides a promising foundation for developing PCL-based therapies for vision-threatening retinal diseases.
