Abstract:
1. A fibrous network-hydrogel composition for use in tissue engineering comprising a matrix including a fibrous polymer network formed of at least one of an electrospun degradable polymer, an electrospun nondegradable polymer or a combination thereof, wherein the degradable polymer is poly L-lactic acid (PLLA), wherein the electrospun fibers have an average diameter between about 2 μm and about 7 μm and are coated with sodium cellulose sulfate (NaCS) wherein the sodium cellulose sulfate is ionically crosslinked onto the fibers, forms a hydrogel, and occupies at least a portion of the interstices between the fibers.
