The CAM assay is a good animal model for vascular tissue engineering. I think the shell membrane maybe a good material for cornea tissue engineering.

Thanks for the answer. Its known that - formally speaking: parts of living animals are the best 'materials' in many biological application. What I share is an idea of using cheap (1EUR/3eggs) material commonly available instead of  use expensive laboratory equipment for making PCLC (or similar) base, eg. for cell cultures tests.

What application do you have in mind? Egg protiens are widely used in vaccines and are not an immunological problem for *most* people: also, if they are being used to make a scaffold for in vitro tissue engineering with the idea that the scaffold will mostly be replaced by the cells' own by the time of implantation, the potential problem will be reduced. Handling the protein with reliably, reproducible results may be more difficult than with synthetic fibres, though, and for any real tissue engineering the main cost is not the fibles (it's mainly in all of the safety and quality assurance infrastructure).

I was thinking about using them as compatibilizers between material and tissue; for  tissue culture on any molded shapes. etc. The structure is similar to made from 'plastics'. It is only idea, because I didn't find any information of using parts of egg instead of materials made in laboratories.

Your idea to use the egg membrane as a cheap biopolymeric material for interphase "implant - biotissues" is seemed valuable. This fresh  reference may be useful  for your research: Pillai M. et al. Egg Shell Membrane – a Potential Natural Scaffold for Human Meniscal Tissue Engineering: An In Vitro Study // RSC Advances, 2015, 5, P. 76019-76025. 

Thanks! Good to know that others had similar idea
