Electrospun nanofibrous scaffolds
are one of the most extensively
used proven candidates for scaffold-based tissue engineering applications
due to their excellent nanoscale architecture and tailorable nature.
Despite the advantages of electrospun scaffolds, drawbacks such as
low mechanical strength and densely packed nanofibers lead to decreased
cell infiltration, preventing diffusion of nutrients and gases. To
overcome these shortfalls, nanofiber yarns formed by directly twisting
thousands of electrospun nanofibers are considered as building blocks
for scaffold fabrication with an appropriate mechanical strength and
porosity to enhance cell infiltration. The study illustrates a unique
and feasible method to synthesize electrospun nanofiber yarns by using
modified collector electrospinning and the yarns were weaved to form
a fabric-like scaffold. α-Mangostin, a plant-based bioactive
compound with cardioprotective, anti-inflammatory and antioxidant
properties was incorporated into the woven scaffold to evaluate its
efficacy as a cardiac patch. Results showed that modification in the
scaffold architecture from spun nanofibers to nanofiber yarns led
to increase in hydrophilicityleading to enhanced protein adsorption,
degradation, cell proliferation, spreading, and infiltration. Here,
we report the fabrication of a 3D woven polymer nanofibrous yarn scaffold
coated with α-mangostin for cardiac patch applications. Results
from the study showed that the scaffold favored stem cell proliferation
and supported the functionality of cardiac cells. These fabricated
3D woven scaffolds showed improved angiogenesis and increased tissue
compatibility in vivo, showing prospects for the
use of a woven scaffold as an ideal template for cardiac tissue engineering
applications.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
