The extracellular matrix of structured microbial communities constitutes the framework that holds the component cells together. Although the presence of cell-to-cell interconnecting matrices appears to be a common feature of structured microbial communities, there is a remarkable diversity in the composition of these matrices. Compounds such as polysaccharides, fimbriae, mating pili, and extrac...

objective: to study the effects of different matrices and co-culture systems on cultured limbal stem cells (lscs). materials and methods: limbal explants were co-cultured with limbal fibroblasts (lf) and/or mouse embryonic fibroblasts (mef) on filter inserts coated with amniotic membrane (am), matrigel (mat) and collagen type i (col). results: this study revealed that am facilitated the cell mi...
