BIOCOMPATIBLE TRANSPARENT SHEET, METHOD OF PRODUCING THE SAME AND CELL SHEET

摘要

It is intended to provide a biocompatible transparent sheet which is highly capable of absorbing a biocompatible or biologically-relevant substance and usable as a novel biological material, enables real-time observation of the proliferation and differentiation of living cells and so on and has sufficient flexibility and softness. This biocompatible transparent sheet is produced by forming a biocompatible ceramic film (2) by, for example, the laser ablation method on a base material (1) being soluble in a solvent (11) in which the biocompatible ceramic is insoluble, dipping the base material (1) having the film formed thereon in the solvent (11) to thereby dissolve the base material (1) and then drying the film (2) thus separated. By seeding and growing cells on the surface of this biocompatible transparent sheet (2) having sufficient flexibility and softness, it is possible to construct a cell sheet which can be directly transplanted into an affected part.
