An Efficient Biosynthetic System for Developing Functional Silk Fibroin-Based Biomaterials.

Long historical evolution and domestication endow silkworms with the super ability to synthesize and secrete massive silk proteins using silk glands. The major component of this secretion consists of silk fibroin, considered a promising biomaterial for tissue repairs and engineering. To further expand the utility of this unique protein, there is a continuing need for silk fibroin functionalization.

Large-scale and cost-effective production of recombinant human serum albumin (rHSA) in transgenic Bombyx mori cocoons.

HSA is considered a versatile natural cargo carrier with multiple bio-functions and applications. However, insufficient supply of HSA has limited widespread use. Although various recombinant expression systems had been applied to produce the rHSA to overcome the limited resource, cost-effective and large scale production of rHSA remains a challenge.
