The present invention pertains to affinity chromatography isolation and purification of extracellular vesicles (EVs). The EVs of the present invention are engineered to enable highly specific binding to e.g. chromatography matrices, which is highly useful for affinity-based isolation and purification of EVs from complex biological fluids such as cell culture medium or biological fluids.

The present invention provides a method of obtaining aggregates containing a rostral hypothalamus tissue and a rostral head ectodermal tissue, a hypophysis precursor tissue and a hypophysis hormone producing cell, by using a serum-free medium (preferably substantially free of growth factor and insulins), forming homogeneous aggregates of stem cells from pluripotent stem cells such as ES cell and the like, which are plated at a high cell concentration, and subjecting the formed aggregates to floating-culture.

Mesenchymal stem cells may be culture for a long period, without using any special apparatus, equipment and the like, in a medium in which seven kinds of nonessential amino acids of glycine, alanine, serine, proline, asparagine, aspartic acid, and glutamic acid are reduced.

Provided is a method for producing a stem cell-derived lacrimal gland tissue, the method comprising isolating SSEA4 and CD104 double positive cells from a self-formed ectodermal autonomous multi-zone (SEAM) cell population derived from pluripotent stem cells and three-dimensionally culturing the isolated cells in a medium with epidermal growth factor (EGF) and a ROCK inhibitor to produce a cell population expressing a lacrimal gland-related protein. The present invention provides a lacrimal gland organoid produced from pluripotent stem cells including iPS cells and thus is very useful for cell-based regenerative therapy for lacrimal gland-related diseases and cell-based research on the diseases.

The present disclosure relates to one or more agents, therapies, treatments, and methods of use of the agents and/or therapies and/or treatments for upregulating production and/or functionality of one or more protein precursors of IDO-1, CTLA-4, PD-1, PD-L1, PD-L2 and INF-y. Embodiments of the present disclosure can be used as a therapy or a treatment for a subject that has a condition whereby the subject's immune system is or is likely to become, dysregulated and where the upregulation of these protein precursors may be of therapeutic benefit.
