These papers have discussed the behavior of Hydro gel which is a type of material having a component liquid component and a solid. Structurally, it is composed of a matrix chain polymers and inflated by a large amount of water or fluid organic. Hydro gels are insoluble network of hydrophilic polymers that are capable of absorbing water and biological fluids. Basis for the creation of hydro gels can serve a number of water-soluble substances, most hydro gels composed of artificially synthesized polymers, proteins and natural molecules. Paper has shown the spatial structure of hydro gels is the result of cross-linking of polymers, which form as a result of an insoluble structure in the surrounding solution. Water content and elasticity of hydro gels are similar to biological tissues, allowing them broad biomedical application. Some other authors suggest that a simple hydro gel can provide an environment that is sufficient for the formation of primary cells. Since then, the biomedical applications of hydrogels greatly expanded to include a dressing for wounds, drug delivery systems to the site of action, the system for dialysis, artificial skin and tissue engineering.

Aspects of Organism

Structural similarities hydro gels and human extracellular matrix such as; extracellular matrix - ECM hydro gels can be applied as a framework for cell tissue engineering. One of the reparative cells, which can form a functional matrix. These papers give an idea that a suitable framework for transplantation and stem, bioactive molecules such as; cytokines and growth factors that will support the desired tissue and control its formation. If regeneration of organs and tissues component data can be used alone or in combination with each other.

Method for measuring properties

The four criteria for building Wycherley hydro gels are comparable with the principles of the framework for cell tissue engineering. The framework must be biologically compatible and transform its shape and structure necessary for integration into the fabric. Hydro gels show close interaction with tissues with low adhesion, as well as hydro gels cause minimal immune response. Therefore, the framework must be able to enter a cell and promote their proliferation without damaging the cell or component output. From the papers we may get ideas that it is necessary for the frame as it is constant for the diffusion of nutrients and metabolites between cells and their local environment. Hydro gels have two additional advantages for tissue engineering (Clarke et al, 1975, pp. 358-368). First, as a substance with potentially minimally invasive, they harden insitu within the defective area of the body, thus avoiding open surgery for implantation. Hydro gels can be sewn under the influence of mild conditions so that the encapsulated cells undergoing physical and chemical changes that cause gelatin. Second, the framework must be capable of biodegradation after cellular component proliferates in soft tissue, and this property have certain hydro gels. The destruction of the time-frame enhances the constructed spatial control tissue.
