The invention relates to the use of dextran sulfate, or a pharmaceutically acceptable salt thereof, in modulating leukocyte activation in allogenic CAR-T cell therapy. Dextran sulfate can be used together with allogenic CAR-T cells to achieve an activation pattern similar to what is obtained in autologous CAR-T cells therapy. Hence, dextran sulfate, or the pharmaceutically acceptable salt thereof, is capable of suppressing unspecific leukocyte activation in connection with allogenic CAR-T cell therapy.

Embodiments of the disclosure encompass methods and compositions related to the ability of RNA to enhance therapeutic activity of fibroblasts. In some embodiments, administration of double stranded RNA is performed through providing polyinosinicpolycytidylic acid (poly (I:C)) or a derivative thereof at a concentration sufficient to induce therapeutic properties and/or to augment therapeutic properties onto said fibroblasts. In one embodiment, enhanced therapeutic activity comprises augmentation of fibroblast migratory activity; efficacy for angiogenesis; efficacy for immune modulation; differentiation ability; production of one or more trophic factors; and/or the ability to resist apoptosis.

Compositions comprising a condensed mesenchymal cell body and a hydrogel are provided. The compositions may further include drugs or growth factors. The condensed mesenchymal cell body may include a connective tissue cell, or even a progenitor cell capable of producing connective tissue extracellular matrices such collagen and glycosaminoglycan. Also provided are methods of treating connective tissue defects, cartilage injury, and cartilage degradation.

The present disclosure relates to a composition for increasing the biological activity of stem cells using mixture 4F. Stem cells treated with mixture 4F according to the present disclosure not only acquire undifferentiated characteristics (stemness), but also have the advantage of improving cell proliferative ability and mobility, and thus, after being transplanted into a body, the stem cells can improve cell survival and engraftment and further enhance the ability to regenerate blood vessels and tissues. Accordingly, the stem cells can have various applications in the fields of stem cell differentiation and ischemic disease prevention or treatment.

The present invention relates to a yeast-derived polysaccharide inducing Treg cells and a use thereof and, more particularly, to a polysaccharide comprising mannan and β-glucan, an composition for immunomodulation comprising the polysaccharide as an active ingredient, a pharmaceutical composition or food comprising the polysaccharide as an active ingredient for prevention or treatment of immune disease or inflammatory disease, a method for preparation of regulatory T cells by using the polysaccharide, a cell therapeutic agent comprising the regulatory T cells prepared by the preparation method as an active ingredient, and a treatment method using same. Even at a low dose, the novel polysaccharide according to the present invention allows the production of tolerogenic antigen presenting cells through the β-glucan and mannan structure retained therein, whereby the novel polysaccharide can induce the differentiation or production of antigen-specific regulatory T cells (Treg cells) to modulate the target immune system with low adverse effects. Therefore, MGCP and the Treg cells induced by the polysaccharide are effective for preventing or treating immune disease or inflammatory disease.

Use of Cistanche deserticola polysaccharide (CDP) in promoting the proliferation and differentiation of female germline stem cells (FGSCs) is provided. Specifically, the addition of CDP in an in vitro cultivation system can promote the proliferation and differentiation of FGSCs, and especially can enhance the in vitro directed differentiation of FGSCs into oocytes, which provides a new research reference for studying the generation of oocytes in vivo and in vitro and also brings a new hope for research on physiological infertility.

A method of producing isothiocyanates includes forming, in a semi-solid or solid callus induction medium, compact callus aggregates from cells obtained from explant material of a Brassica oleracea L. plant. The method includes transferring cells from the callus aggregates, e.g. transferring the callus aggregates, to a suspension culture in a liquid medium in a shake flask, the liquid medium containing a plurality of elicitors. The method further involves transferring, after culturing in the shake flask, cells from the suspension culture to a further suspension culture in a bioreactor containing the elicitors. The method includes extracting and/or purifying of at least one isothiocyanate from cells obtained from the bioreactor. The elicitors have chitosan and salicylic acid to increase accumulation of benzyl isothiocyanate or any other isothiocyanate.

Embodiments of the disclosure provide methods and compositions related to improving cardiomyocyte production by exposing starting cells to ETV2 and/or VEGF. The starting cells in specific embodiments are fibroblasts and/or endothelial cells, and following exposure to ETV2 and/or VEGF the resultant cells are exposed to one or more cardiomyocyte transdifferentiation factors, such as GATA4, myocyte enhancer factor-2c (Mef2c), T-box transcription factor 5 (TBX5), or a combination thereof. The produced cardiomyocytes are provided to individuals in need thereof, in particular embodiments.

Methods and compositions for pre-conditioning, transduction and/or hypothermic preservation of vascular cells transduced with nucleic acid constructs for expressing pro-angiogenic factors are provided. Also provided are uses of such cells in therapy.

Disclosures herein are directed to first compositions comprising exosomes and extracellular matrix components and their use thereof. Also described are methods and kits wherein these first compositions are packaged and used with second compositions comprising mesenchymal stem cells. The first and second compositions are derived from the same tissue source using tangential flow filtration.
