It has been reported that fibroin from A. mylitta and A. pernyi silks had better cell attachment and growth than B. mori silk [3] and [17]. In addition to using natural fibroin from mulberry and non-mulberry silks, fibroin protein from the glands of B. mori and A. mylitta silkworms has also been studied for potential tissue engineering applications [14]. Although sericin in silk is generally considered to be cytotoxic, it has recently been reported that sericin can promote proliferation of cells in serum-free media and is suitable for biomedical and biotechnological applications [18]. Studies have also been done to understand the potential of using spider silks for medical applications [6] and [7]. Both regenerated and recombinant spider silk has been developed for various applications [7] and [19].
