Culture insert assembly and system for culture, transfer, and analysis

1. A culture system comprising: a base comprising a multiwell plate; an insert plate comprising a plurality of culture insert assemblies which are integrally formed as part of the insert plate, wherein each culture insert assembly comprises a culture surface element that is removably mounted to a culture insert body; a transfer plate comprised of a plurality of openings for engaging a plurality of culture surface elements for facilitating transfer of culture surface elements between an insert plate and the transfer plate; wherein a culture surface element comprises one or more engagement elements to contact and be receivingly engaged by the transfer plate; and a removable lid.

2. The culture system of claim 1 , wherein the culture insert assemblies of the insert plate correspond in number and spatial arrangement to that of the wells in the multiwell plate.

3. The culture system of claim 1 , wherein each culture surface element comprises a microporous matrix.

4. The culture system of claim 3 , wherein the microporous matrix further comprises one or more culture components.

5. The culture system of claim 1 , wherein the transfer plate lacks a bottom surface covering the plurality of openings.

6. The transfer plate of claim 1 , wherein the culture system lacks a bottom surface covering the plurality of openings.

7. A method for transferring a plurality of culture surface elements, from an insert plate comprising a plurality of culture insert assemblies, to a transfer plate, the method comprising (a) aligning the plurality of culture insert assemblies containing culture components comprised of cultured cells or cultured tissue, of an insert plate comprising a plurality of culture insert assemblies, with corresponding openings of a transfer plate; (b) contacting one or more engagement elements of each culture surface element, of the plurality of culture surface elements, with one or more guiding elements associated with a corresponding opening of a transfer plate, such that the plurality of culture surface elements become removably attached to the transfer plate through engagement of the engagement elements of the culture surface elements, of the plurality of culture surface elements, with the guiding elements of the transfer plate and (c) detaching the plurality of culture surface elements from the culture insert assemblies of the insert plate by disengaging attachment elements of the plurality of culture surface elements from attachment elements of the insert plate, thereby resulting in a transfer plate now comprising a plurality of culture insert assemblies, and the insert plate lacking culture surface elements.

8. The method of claim 7 , wherein a culture surface element further comprises a microporous matrix and one or more culture components.

9. A culture system comprising: a base comprising a multiwell plate; an insert plate comprising a plurality of culture insert assemblies which are integrally formed as part of the insert plate, wherein each culture insert assembly comprises a culture surface element that is removably mounted to a culture insert body through one or more attachment elements of the culture insert body removably fixedly received by one or more attachment elements of a culture surface element, wherein an opening in the insert plate is formed by an opening of a culture insert assembly, and wherein a culture surface element comprises a microporous matrix and one or more engagement elements to contact and be receivingly engaged by a transfer plate; a removable lid; and a transfer plate comprised of a plurality of openings for engaging a plurality of culture surface elements.

10. The culture system of claim 9 , wherein the culture insert assemblies of the insert plate correspond in number and spatial arrangement to that of the wells in the multiwell plate.

11. The culture system of claim 9 , wherein the culture insert assemblies of the insert plate correspond in number and spatial arrangement to that of the plurality or openings of which the transfer plate is comprised.

12. The culture system of claim 9 , wherein the transfer plate lacks a bottom surface covering the plurality of openings.

13. The culture system of claim 9 , wherein the microporous matrix further comprises one or more culture components.

14. A culture system comprising: an insert plate comprising a plurality of culture insert assemblies which are integrally formed as part of the insert plate, wherein an opening in the insert plate is formed by an opening of a culture insert assembly, where a culture insert assembly comprises a culture surface element removably attached to a culture insert body through one or more attachment elements of the culture insert body removably fixedly received by one or more attachment elements of a culture surface element, and wherein a culture surface element comprises a microporous matrix and one or more engagement elements to contact and be receivingly engaged by a transfer plate; and a transfer plate comprised of a plurality of openings corresponding in number and spatial arrangement to that of the plurality of culture insert assemblies of the insert plate, and wherein the transfer plate lacks a bottom surface covering the plurality of openings.

15. The culture system of claim 14 , further comprising one or more of (a) a multiwell plate, and (b) a removable lid.

16. The culture system of claim 14 , wherein the microporous matrix further comprises one or more culture components.

17. A method for transferring a plurality of culture surface elements from a transfer culture assembly to an insert plate; wherein the insert plate comprises a plurality of culture insert bodies, with one or more attachment elements of a culture insert body to be received by one or more attachment elements of a culture surface element; wherein the transfer culture assembly comprises a plurality of culture surface elements removably attached to a transfer plate, the method comprising: (a) spatially aligning the plurality of culture insert bodies of the insert plate with the plurality of culture surface elements removably attached to the transfer plate so that each culture surface element of a plurality of culture surface elements is spatially aligned with a corresponding culture insert body of a plurality of culture insert bodies, (b) contacting one or more attachment elements of each culture surface element of a plurality of culture surface elements with one or more attachment elements of a corresponding, spatially aligned culture insert body of a plurality of culture insert bodies, such that the plurality of culture surface elements become removably attached to the plurality of culture insert bodies through contact and engagement of the respective attachment elements, in forming culture insert assemblies, and (c) detaching the culture surface elements from the transfer culture assembly in disengaging the culture surface elements from the transfer plate; thereby transferring a plurality of culture surface elements from the transfer culture assembly to the insert plate.
