Provided herein are methods for expanding populations of regulatory B cells comprising treating a population of B cells with IL-4 and CD40 ligand. Further provided herein are methods of expanding populations of regulatory T cells comprising expanding a population of T cells under Treg expansion conditions and selecting for CD9.sup.+ Tregs. Also provided herein are methods of treating immune disorders with the regulatory B cells and/or regulatory T cells.

In some embodiments, methods of delivering a therapeutically effective amount of an expanded number of tumor infiltrating lymphocytes obtained from tumor remnants to a patient in need thereof, for the treatment of a cancer, are disclosed.

The present invention discloses a composition comprising extracellular vesicles (EVs) of placenta tissue derived CD106.sup.high CD151.sup.+Nestin.sup.+ mesenchymal stem cells (MSCs). In a first aspect, the invention relates to a particular method to prepare these EVs. In a second aspect, the invention relates to a therapeutic, a diagnostic, a veterinary or a cosmetic composition comprising the extracellular vesicles (EVs) obtained by said particular method. In a third aspect, the invention relates to a composition comprising these EVs, for use as a medicament for treating subjects suffering from an ischemic disease, a disorder of the circulatory system, an immune disease, an organ injury or an organ function failure.

The present invention relates to an accelerated method to generate high yields of type-1 polarizing mRNA loaded dendritic cells for use in immunotherapy, and in particular for use in cancer vaccination.

The present invention provides methods and compositions for Th9-cell mediated cancer therapy.

Disclosed herein are methods of expanding adherent stromal cells, including, inter alia, multi-step methods. Also disclosed are cells produced by the methods, which may be adherent stromal cells, for example placental adherent stromal cells. Further disclosed are pharmaceutical compositions comprising the cells. Additionally, methods of producing and utilizing the compositions, for example for therapeutic uses, are described.

CD206-positive M2 macrophage-targeting exosomes and methods of use thereof are provided. One embodiment provides a CD206-positive M2 macrophage-targeting exosome expressing a CD206 binding peptide and an Fc portion of IgG2b. In some embodiments, the CD206 binding peptide is encoded by a nucleic acid sequence having 95%, 99%, or 100% sequence identity to SEQ ID NO:2 and the IgG2b is encoded by a sequence having 95%, 99%, or 100% sequence identity to SEQ ID NO:6.

Provided by the disclosure are compositions and methods for modulating differentiation of regulatory T cells. In some embodiments, methods include selectively decreasing IL-23R activity and/or IL-23R expression without significantly decreasing IL-12RP activity and/or IL-12RP expression.

The present disclosure provides signal transducer and activator of transcription (STAT)-activated macrophages, compositions comprising STAT-activated macrophages, methods of making STAT-activated macrophages, and methods of treating diseases, e.g., cancer, by administering a therapeutically effective amount of STAT-activated macrophages.

Novel MSC stem-cell culture and therapy methods and culture medium compositions for the purpose of inducing, activating, or priming discrete uniform cell phenotypes to selectively promote or suppress inflammation and immunity, yielding polarized, primed, activated, or induced cells used in cell-based therapy.
