What is electrospinning?
Electrospinning is a technique used to produce fibers from polymer solutions by applying a high voltage to create a charged jet that solidifies into fibers.
What is poly(glycerol-dodecanoate)?
Poly(glycerol-dodecanoate) is a biodegradable polymer that can be used to create scaffolds for cell culture and tissue engineering applications.
How do the fibers support cell growth?
The fibers provide a scaffold that mimics the extracellular matrix, allowing cells to attach, survive, and differentiate.
What types of cells were used in this study?
Mouse embryonic stem cells were used to evaluate the fiber scaffolds' ability to support cell growth and differentiation.
What are the potential applications of these fibers?
