The present invention relates to a method of patterning and chopping 3D organoids prepared from human pluripotent stem cells, culturing the stem cells or progenitor cells, and inducing the differentiation thereof to obtain a large amount of finally differentiated cells. Compared to cells differentiated by a conventional differentiation method, the cells obtained in a large amount exhibit remarkably superior effects in terms of reproducibility, stability, and functionality, and thus are expected to be very useful for cell therapeutic agents or for the screening of therapeutic drugs.

Provided are a novel compound having CDK8 and/or CDK19 inhibitory activity, and a production method for Tregs. The treatment of T cells with a CDK8 and/or CDK19 inhibitor induces Foxp3 in the T cells. Foxp3.sup.+ T cells can be induced by treating Foxp3.sup.− T cells with the CDK8 and/or CDK19 inhibitor in vitro. Thus, Tregs can be induced.

The present invention provides methods for preselecting TILs based on PD-1 expression, as well as methods for expanding those preselected PD-1 positive TILs in order to produce therapeutic populations of TILs with enhanced tumor-specific killing capacity (e.g., enhanced cytotoxicity).

Relapse in adoptive cell transfer of CAR-T cells is often the result of CAR-T cells disappearance. Disclosed herein a method for enhancing CAR-T cell therapy in a subject, comprising administering to a subject undergoing adoptive cell transfer of therapeutic CAR-T cells an Akt inhibitor in an amount effective to increase the persistence of the CAR-T cells. As a consequence, a subject treated with a combination of CAR-T cells and an Akt inhibitor is less likely to relapse. Therefore, also disclosed herein is a method for treating a subject, comprising adoptively transferring to the subject an effective amount of a composition comprising a CAR-T cell, and administering to the subject an Akt inhibitor in an amount effective to increase the persistence of the CAR-T cells.

Compositions and methods for inducing pluripotent stem cells into retinal ganglion cells for administration to a subject for treating progressive optic neuropathies, thereby alleviating symptoms of such disorders including glaucoma.

The present application discloses a cell culture media for growth, maintenance and induction of reversion to a less mature state of a cell comprising a MUC1* activating ligand.

The invention relates to differentiation methods for progenitor cells, e.g. mammalian epithelial stem cells, differentiation media for use in said methods, organoids and cells obtainable by said methods and uses, including therapeutic uses, thereof.

Cranial placodes are embryonic structures essential for sensory and endocrine organ development. The efficient derivation of cranial placodes from human pluripotent stem cells is disclosed where the timed removal of the BMP inhibitor Noggin, a component of the dual-SMAD inhibition strategy of neural induction, triggers placode induction at the expense of CNS fates. Further fate specification at the pre-placode stage enables the selective generation of placode-derived trigeminal ganglia capable of in vivo engraftment, mature lens fibers and anterior pituitary hormone-producing cells that upon transplantation produce hormones including, but not limited to, human growth hormone and adrenocortiocotropic hormone in vivo. Alternatively, anterior pituitary hormone-producing cells are generated in cell culture systems in vitro.

The present invention provides for identification and use of small molecules to induce pluripotency in mammalian cells as well as other methods of inducing pluripotency.

The technology relates in part to methods and compositions for ex vivo proliferation and expansion of epithelial cells.
