A hybrid assembly by encapsulation of human cells within mineralised beads for cell therapy.

Background: The design of new technologies for treatment of human disorders such as protein deficiencies is a complex and difficult task. Particularly, the construction of artificial organs, based on the immunoisolation of protein-secreting cells, requires the use of suitable materials which have to be biocompatible with the immunoisolated cells and avoid any inappropriate host response.

Methodology/principal Findings: This work investigates the in vivo behavior of mechanically resistant hybrid beads which can be considered as a model for artificial organ for cell therapy.

Hybrid shell engineering of animal cells for immune protections and regulation of drug delivery: towards the design of "artificial organs".

Background: With the progress in medicine, the average human life expectancy is continuously increasing. At the same time, the number of patients who require full organ transplantations is augmenting. Consequently, new strategies for cell transplantation are the subject of great interest.

Whole-cell based hybrid materials for green energy production, environmental remediation and smart cell-therapy.

This critical review highlights the advances that have been made over recent years in the domain of whole-cell immobilisation and encapsulation for applications relating to the environment and human health, particularly focusing on examples of photosynthetic plant cells, bacteria and algae as well as animal cells. Evidence that encapsulated photosynthetic cells remain active in terms of CO(2) sequestration and biotransformation (solar driven conversion of CO(2) into biofuels, drugs, fine chemicals etc.), coupled with the most recent advances made in the field of cell therapy, reveals the need to develop novel devices based on the preservation of living cells within abiotic porous frameworks.

Encapsulation of cells within silica matrixes: Towards a new advance in the conception of living hybrid materials.

Living cells can be considered as a highly efficient molecular engines spatially enclosed, remaining however fragile. By combining cells with silica materials in an appropriate way, novel living hybrid material technologies can be designed. After showing the real interplay between silica species and living organisms in nature, this featuring article summarizes the considerable progress in cell encapsulation into silica matrixes.
