Figure 1. Engineering the Stem Cell Niche. The ability to assembly natural and manmade components into idealized biosynthetic 3D architectures requires a detailed understanding of the environment, along with the technology and expertise to manipulate them. This multiscale and multi-expertise approach is expected to lead to unprecedented breakthroughs in tissue engineering and biofabrication that benefit human health for an improved quality of life.

In search of the Holy Grail: Engineering the stem cell niche

There is no other biomedical frontier that offers the stunning potential of human pluripotent stem cells and their progenitors in therapeutic applications to ease human suffering or in their ability to provide insights into development and diseases. Cell plasticity for reprogramming has revealed new opportunities in cell-based therapies and informed on lineage specification. What precisely defines each stem cell type or its transit amplifying progenitors that will lead to differentiated adult tissues is still being determined. Challenges remain in cell expansion, directed differentiation and environmental regulation of pluri- and multi-potent cells that avoid unwanted outcomes in transplantation therapies. Traditional culturing methods are giving way to a revolution in tissue engineering and biofabrication. The key to success is a multidisciplinary partnership of biologists, engineers, material scientists and clinicians. This strategy brings together cutting edge technologies and diverse expertise to bridge nano- to micro- to macroscale communication networks. Here, we discuss prominent technologies being applied to engineer the stem cell and tissue niche in vitro for the construction of 3D tissue architectures with integrated vascular networks.

Combining perspectives: Multiscale integration of Stem Cell research

Issue 6 2009, Past issues / 12 December 2009 /

The promise of stem cell-based therapy is predicated on harnessing the plasticity of stem cell phenotypes to repair or replace damaged tissues. As technologies for detecting, isolating, modifying, and tracking stem cells improve, the very definition of what constitutes a stem cell is now an open question. Addressing this fundamental problem has triggered an explosion […]
