A three-dimensional (3-D) culture “Petri-dish” for research in regenerative medicine, biotechnology and clinical translation is described. This 3-D perfusion culture dish is to advance in vitro culture tools from static 2-D to dynamic 3-D perfusion culture. Interwoven hollow fiber capillary membranes divide the “Petri-dish” culture space into a controllable 3-D pattern of different compartments, serving the functions of the organ's larger vasculature. These physically active scaffolds, which can be suitable for cell adhesion or cell aggregate immobilization, offer a supply of cells with high-performance mass exchange including gas supply and under perfusion conditions. In contrast to static and discontinuous medium supply, a dynamic culture can be achieved with continuous or alternating medium supply and integral oxygenation. They provide a more physiologic supply in the cell macro environment, including homeostasis of oxygen, pH, nutrition, soluble factors, and gradients of metabolites for the cells. Also, medium perfusion can be achieved. Consequently the invention was made for cultures at tissue density, especially stem cells and support cells, which strive to create their own stem cell niche.

A two-mode therapeutic mattress system is provided, including a non-powered air mattress, a pressure dispersion cushion, and a selectively operable air diffusion coverlet in a common modular assembly for improved medical management of skin care. The non-powered air mattress includes longitudinal air cylinders providing a static air support system inflated to predetermined pressure. The longitudinal air cylinders are in pressure communication with elasticized reservoirs, in that the air level in the elasticized reservoirs dynamically reacts to changes in pressure in the longitudinal air cylinders, for example upon receipt of a patient upon the mattress system. The pressure dispersion cushion facilitates pressure relief with a number of lateral and longitudinal cuts resulting in a plurality of separate upright support cells, the size and construction of which may vary over the surface of the pressure dispersion cushion so as to provide selective support characteristics. The air diffusion coverlet contains a plurality of air pockets. The air diffusion coverlet operates in two modes: a “therapy mode” such that compressed air from an air compressor is pumped to the air diffusion coverlet, and an “off” mode in which the air pockets collapse to provide a suitable and relatively smooth bedding component to the therapeutic mattress system. The non-powered air mattress, pressure dispersion cushion, and selectively operable air diffusion coverlet cooperate to provide a single product that addresses localized pressure, maceration, shear stress, and dynamic changes in a patient's condition during the course of time.
