A method for culturing primary gynecological tumor cells and culture medium used therein. The method includes using mild cell dissociation reagents to treat a gynecological solid tumor tissue, to ensure the vitality of tumor cells in the tissue to the greatest extent; preparing a special serum-free medium, and using a suspension culture system to culture solid tumor cells derived from a gynecological tumor in vitro to ensure the normal expansion of tumor cells and eliminate interference from normal cells to the greatest extent. The primary gynecological tumor cell culture obtained by the method of the present invention can be used for various cell-based in vitro experiments, second-generation sequencing, construction of animal models, construction of cell lines and the like. It is foreseeable that this culture method has broad application prospects in the fields of gynecological tumor research and clinical diagnosis and treatment.

The invention relates to the use of matrix cells for obtaining a micro hair follicle and to the use thereof for evaluating the effect of cosmetic, pharmaceutical or dermatological products and also for the prophylactic or therapeutic treatment of a state of reduced pilosity.

The present invention provides a method for producing a unilocular adipocyte including inducing differentiation into unilocular adipocytes of mesenchymal cells having differentiation potency into adipocytes by culturing the mesenchymal cells in suspension in a liquid medium composition capable of culturing cells or tissues in suspension, wherein the liquid medium composition contains a polymer compound having an anionic functional group that binds via a divalent metal cation to form a structure capable of suspending cells or tissues, and the method wherein the polymer compound is polysaccharide, preferably polysaccharide containing a glucuronic acid moiety, more preferably deacylated gellan gum, diutan gum or xanthan gum or a salt thereof.

A method of obtaining 3D cell structures including differentiated human hepatic cells. The method includes: a first step of culturing stem cell-derived or immortalized human hepatic progenitors in a non-adherent culture vessel, preferably a low or ultra-low attachment culture vessel; a second step of transferring the stem cell-derived or immortalized human hepatic progenitors to a culture medium including methacrylated gelatin (GelMa), thereby embedding the stem cell-derived or immortalized human hepatic progenitors in a GelMa matrix; and a third step of covering the GelMa matrix with culture medium and culturing the stem cell-derived or immortalized human hepatic progenitors embedded in the GelMa matrix, thereby obtaining 3D cell structures including differentiated human hepatic cells. Also, methods for engineering an artificial liver model or an artificial liver organ, and for assessing in vitro the metabolism, toxicity and/or therapeutic effects of a compound.

Provided are populations of cells enriched for MSC-derived cells that are: CD90.sup.+; CD105.sup.+; CD45.sup.−; as well as TIMP-1 secretion high, and MMP13 gene expression low. Such populations of cells are useful as medicaments in contexts where it is desired to make use of the trophic or immunosuppressive therapeutic effects of MSCs, but to avoid activity associated with the capacity of MSCs to undergo phenotypic differentiation. Populations of cells of the invention are useful in the treatment of a condition selected from the group consisting of: osteoarthritis; myocardial infarction; meniscus cartilage injury (such as torn meniscus); ligament injury (such as torn ligament); injuries to the skin; and soft tissue injury. They may also be used in treatment of a disease selected from the group consisting of: haematological disease; graft-versus-host disease; and inflammatory disease.

Disclosed is a method for culturing urine-derived kidney stem cells, which belongs to the field of cell biology. The method comprises the following steps: isolating cells from the urine, and then culturing the cells with a culture medium of urine-derived kidney stem cells on feeder cells to obtain the urine-derived kidney stem cells, wherein the feeder cells are fibroblasts, and the culture medium of urine-derived kidney stem cells contains 200-300 mL of DMEM medium, 200-300 mL of F12 medium, 20-70 mL of fetal bovine serum, 0.2-2 mM of L-glutamine, 1-14 ng/mL of insulin, 0.1-1 ng/mL of epidermal growth factor, 5-30 μg/mL of adenine, and 2-20 μg/mL of hydrocortisone. By using the method, kidney stem cells with high proliferation capacity and specificity can be obtained and applied, and thus the regenerative outcome of the kidney tissue after injury can be improved.

Embodiments of the disclosure provide methods and compositions that facilitate cancer treatment including at least because they concern therapies that circumvent the tumor microenvironment. In specific embodiments, compositions are utilized for therapy that utilize NK cells that are protected from the direct inhibition of their activity (using TGF-beta inhibitors) and/or that are indirectly protected from TGF-beta (using integrin inhibitors). In specific embodiments, the NK cells have deficient expression and/or activity for TGF-beta Receptor 2 and/or glucocorticoid receptor.

This disclosure relates to endothelial and smooth muscle like vascular tissue produced from urine cells. In certain embodiments, the disclosure relates to methods of producing endothelial and smooth muscle like vascular tissue by exposing urine derived cells with ETV2 in a first growth media under conditions such that the cells are modified to form a pool of cells expressing increased levels of endothelium surface markers and thereafter exposing the pool of cells to a second growth media under conditions such that the cells are modified to form tissue containing cells expressing increased levels of smooth muscle surface markers in addition to the endothelium surface markers. In certain embodiments, the disclosure relates to using cells and tissues reported herein for the treatment of vascular, cardiac, and wound healing indications.

The present invention relates to methods for developing engineered T-cells for immunotherapy and more specifically to methods for modifying T-cells by inactivating at immune checkpoint genes, preferably at least two selected from different pathways, to increase T-cell immune activity This method involves the use of specific rare cutting endonucleases, in particular TALE-nucleases (TAL effector endonuclease) and polynucleotides encoding such polypeptides, to precisely target a selection of key genes in T-cells, which are available from donors or from culture of primary cells. The invention opens the way to highly efficient adoptive immunotherapy strategies for treating cancer and viral infections.

This invention pertains to a novel population of lymphocytes, methods for producing these, and their use in the treatment of diseases.
