Scaffolds, stem cells, and tissue engineering: A potent combination!

Stem cells, either from embryonic or adult sources, have demonstrated the potential to differentiate into a wide range of tissues depending on culture conditions. This makes them prime candidates for use in tissue engineering applications. Current technology allows us to process biocompatible and biodegradable polymers into three-dimensional (3D) configurations, either as solid porous scaffolds or hydrogels, with controlled macro and/or micro spatial geometry and surface chemistry. Such control provides us with the ability to present highly controlled microenvironments to a chosen cell type. However, the precise microenvironments required for optimal expansion and/or differentiation of stem cells are only now being elucidated, and hence the controlled use of stem cells in tissue engineering remains a very young field. We present here a brief review of the current literature detailing interactions between stem cells and 3D scaffolds of varying morphology and chemical properties, concluding with remaining challenges for those interested in tissue engineering using tailored scaffolds and stem cells.

Campfire culture and computer culture: Museums of the present

In Australia indigenous peoples have never had a treaty with the dominant cultures; and their on-going marginalisation is some testimony to this. However, they have not languished entirely in a policy free environment: media is one area where some policy advances have been made; but media policy development has experienced a number of problems. It has tended to be monolithic in a situation demanding multi and complex treatments. And funding, as always, never seems sufficient to meet those multi and complex needs. This paper examines a small remote community on the island of Milingimbi off the northern coast of Arnhem Land in Australia's far north. People in East Arnhem Land refer to themselves collectively as Yolngu. This community is not typical of many documented cases of media relations between indigenous and non-indigenous peoples; however, the fact that it tends to overturn much of the conventional scholarship surrounding indigenous peoples and the media, helps shed new light on the inadequacy of not only monolithic media policy, but the inadequacy of media-only approaches to policy. Arguably, the significance of the media in Milingimbi is part of a 'triangulated' relationship between indigenous and dominant cultures. That triangulation also involves appropriate forms of government and education, which coupled with appropriate media appear to offer new ways of seeing self-government alongside relative cultural and economic autonomy.
