The present invention provides improved methods for expanding TILs and producing therapeutic populations of TILs, including novel methods for selecting TILs responsive to a mutant polypeptide expressed by cancer cells and not expressed in normal tissue.

Described herein are cellular scaffolds comprising a cell reservoir, a guide attached to the cell reservoir constructed from one or more biodegradable polymers, and a population of folliculo-genic cells. The cellular scaffolds are useful in growing hair.

This method for producing a cell cluster group comprises: a step for putting, into a well, a cell suspension obtained by suspending dispersed cells in a medium, using a cell incubator which includes the well and two or more recesses formed in the bottom of the well and in which the area of an opening of each recess in plan view is at most 1 mm.sup.2; a step for centrifuging the cell incubator; and a step for culturing the dispersed cells in the recesses.

Embodiments of the present disclosure generally relate to compositions comprising hydrogel-encapsulated/dispersed beta cells, compositions comprising hydrogel-encapsulated/dispersed beta-cell spheroids, processes for forming such compositions, and uses of the compositions. In an embodiment, a composition is provided that includes a first component comprising a hydrogel, the hydrogel comprising, in polymerized form, one or more photoreactive monomers and a thiol linker. The composition further comprises a second component comprising a plurality of beta cells dispersed or encapsulated within the hydrogel.

The present invention relates to methods for the specific separation of target cells from a biological sample, comprising specific binding of the target cells to phase-change hydrogel compositions and separation of respective cell-hydrogel complexes by counter-current centrifugation.

A flowable birth tissue composition fabricated from birth tissue is provided. Methods of processing a mammal's placental tissue to form a flowable birth tissue composition are provided. Various methods of treatment and uses are also provided.

A temperature-sensitive cell culture composition is provided. The temperature-sensitive cell culture composition includes a hydrogel, a cellulose, a gelatin and a collagen. Based on 1 part by weight of the collagen, a content of the hydrogel is between 0.03 parts by weight and 60 parts by weight, a content of the cellulose is between 150 parts by weight and 360 parts by weight, and a content of the gelatin is between 21 parts by weight and 12 parts by weight. In addition, a method for using the temperature-sensitive cell culture composition, a method for forming the temperature-sensitive cell culture composition, and a use of the temperature-sensitive cell culture composition are also provided.

The present disclosure provides a method of fabricating curvature-defined (C-D) or shape-defined (S-D) concave and convex polydimethylsiloxane (PDMS) surfaces and a method of fabricating C-D or S-D convex and concave gel surfaces for use in cell and tissue culturing and in other surface and interface applications, and provides a method of using C-D or S-D convex and concave surfaces with varying curvatures to direct cell attachment, spreading, and migration.
