Apparatus for applying stress to cell cultures
First Claim
1. An apparatus for applying stress to cell cultures comprising:
- at least one cell culture plate having one or more wells thereon, with each of said wells having a substantially planar base formed at least partially of an elastomeric membrane made of a biocompatible polyorganosiloxane composition, with said elastomeric membrane having an upper surface treated to permit cell growth and attachment thereto by means of the incorporation at said upper surface of a substance selected from the group consisting of an amine, a carboxylic acid, or elemental carbon, and vacuum means for controlling subjecting said elastomeric membrane to the pulling force of a vaccum.

Abstract
A polyorganosiloxane composition having a biocompatible surface thereon is disclosed. The biocompatible surface results from the derivatization, or amination, of the surface intended for cell contact. More specifically, the present invention is a polyorganosiloxane composition in which the surface is either treated with a primary amine and optional peptide or the surface is cocured with a primary amine-containing silane or siloxane. The aminated polyorganosiloxane has utility as a cell culture substrate or in a variety of artificial organ applications such as breast implants, synthetic blood vessels, joints, tendons and heart valves. A vacuum apparatus for use with specialized cell culture plates incorporating the biocompatible polyorganosiloxane composition is also disclosed.
