摘要:
The present invention provides methods of producing a surface with enhanced cell-adhesive properties comprising applying a stress to a polymeric matrix. The strained matrix is then modified by grafting a self-assembled monolayer onto the strained matrix, with the self-assembled monolayer comprising at least one exposed functional group. At least one cell-adhesive molecule can then be coupled to the at least one exposed functional group on the self-assembled monolayer to produce a surface with enhanced cell-adhesive properties.
摘要:
The present invention relates to cell adhesion promoting (“CAP”) peptide combinations that promote cell attachment or cell adhesion to culture surfaces that are otherwise cell adhesion resistant “CAR”. The invention provides combination of peptides that, when covalently coupled to a CAR layer such as hyaluronic acid that has been created on a polystyrene surface, promote cell attachment, growth differentiation, and execution of other desired cellular functions in culture.

摘要:
An automated system and method for identifying agents capable of eliciting a phenotypic change in a cell-type. The method includes the steps of providing a statistical design including generic factor names, factor levels and experimental runs, and utilizing a software program to generate a computer representation of the statistical design by automatically mapping the identities of the agents to the generic factor names, concentrations or amounts of the agents to the factor levels, and the locations of the receptacles to the experimental runs. The method also includes placing different mixtures of single agents, such as peptones, into receptacles in the array based on the computer representation of the statistical design, contacting the placed mixtures with cells, acquiring experimental data from the contacted cells, and utilizing a processor including an algorithm for comparing the acquired data with the statistical design to identify peptone combinations and concentrations that optimize cell culture conditions.

摘要:
The current invention relates to methods of producing a surface with enhanced cell-adhesive properties comprising treating a pre-formed surface such that at least one intermediate reactive group is exposed on the surface. The exposed intermediate reactive group is then reacted to create a self-assembled monolayer, comprising at least one reactive group. The self-assembled monolayer is created non-mechanically. The reactive group is then coupled to at least one cell-adhesive molecule. The current invention also relates to cell culture devices comprising at least one oxygen-sensing compound and a cell-adhesive molecule.
