Figure 4

Confocal laser microscopic images of primary human chondrocyte cell attachment, growth and proliferation on individual 3D meniscus silk scaffolds layers in chondrogenic medium. Initial cell attachment on day 1 (a, b, c) and confluent cell covering scaffold pores on day 28 (d, e, f). Close up images showing cell alignment and spreading within pores and laminas (g, h, i). First/top scaffold layer is represented by (a, d, g); second/middle layer (b, e, h) and third/bottom layer (c, f, i). Scale bar represents 300 microns.
