The present application provides methods and processes for making and using a fibronectin composition, as well as methods for treating ocular conditions and/or disorders with the cellular fibronectin composition described herein.

It is an object of the present invention to provide, for instance, a method for evaluating a function, such as transforming potential, of multiple different genes of interest, and a method capable of evaluating drug sensitivity of a subject having each gene of interest. The present invention relates to, for instance, a method for evaluating multiple different genes of interest, comprising the steps of: integrating, into host cell genomic DNA, polynucleotides each comprising a tag sequence and a gene of interest or a fragment thereof linked to the tag sequence; mixing a plurality of different host cells having the different polynucleotides integrated therein; culturing the mixed host cells; extracting the genomic DNA from the cultured host cells; quantifying each of the polynucleotides in the extracted genomic DNA based on the tag sequence; and determining a relative cell count of each of the host cells having the respective polynucleotides after the culturing, based on the quantified values for the polynucleotides.

Provided are methods and compositions to target delivery of cells to a tissue lesion, thereby treating the lesion. For example, biotinylated antibodies with affinity to a lesion epitope are administered at the lesion. Reparative cells including avidin and biotin are then administered at the lesion. The reparative cells are targeted to the lesion via avidin-biotin bridges to the antibodies, with additional cells recruited to the lesion via cell-to-cell avidin-biotin bridges. In certain examples, antibody-reparative cell complexes are formed by mixing the biotinylated antibodies with the reparative cells including avidin and biotin. The complexes are then administered at the lesion. In other examples, multivalent antibodies are used to target reparative cells to the lesion, such as by binding an epitope at the lesion and an epitope present on the reparative cell. In other examples, the antibodies are chemically linked to a reparative cell or to a nanosome containing a therapeutic agent.
