Observation of proliferation and attachment of three different cell types on nano-fibrous silk film & scaffold

Attachment and viability of different cell types(fibrioblast, chondrocyte and osteoblast) was observed on two forms of silk (mat & Three-dimensional scaffolds). The osteoblasts behaviors cultured on silk mat were significantly higher than that found on 3-D silk fibroin scaffold (3-D SF scaffold). In the MTT assay, the cell viability of fibroblasts, chondrocyte and osteoblasts seeded on 2-D nanofiber mat was (2-D mat) significantly higher than that found on 3-D SF scaffold. Similar result could be seen from SEM observation and cell attachment study. However, alkaline phosphatase activity was significantly increased on 3-D SF scaffold than on2-D nanofiber.
