The invention provides methods of making immune effector cells (e.g., T cells, NK cells) that can be engineered to express a chimeric antigen receptor (CAR), and compositions and reaction mixtures comprising the same.

A method of preparing a bone graft. An osteoconductive matrix is placed in a receptacle. Bone marrow aspirate is provided that includes plasma, progenitor cells, hematopoietic cells, endothelial cells, red blood cells, white blood cells, platelets, bone, cartilage, thrombus or combinations thereof. The bone marrow aspirate is passed through the receptacle. At least a portion of bone marrow aspirate is retained in the receptacle. The portion of the bone marrow aspirate retained in the receptacle becomes associated with the osteoconductive matrix to form the bone graft.

The present invention relates to a novel method for isolating and culturing dermal papilla cells. Particularly, in the isolation and culture method of the present invention, by culturing dermal papilla tissue isolated from the scalp under hypoxic conditions, dermal papilla cells separated from the dermal papilla tissue are rapidly attached to a culture plate, thus having the effect of shortening the period of establishing (harvesting) dermal papilla cells, and the isolated and cultured dermal papilla cells have immunocompatibility, and thus can be effectively used for the allogeneic transplantation of dermal papilla cells.

A method is disclosed for modifying a sheet-shaped cell culture containing at least two types of cells. The method includes soaking the sheet-shaped cell culture in a low nutrient isotonic solution; and changing a content ratio of the at least two cell types constituting the sheet-shaped cell culture.

The present invention is directed to the use of microfluidics in the preparation of cells and compositions for therapeutic uses.

The present invention is directed to methods and compositions regarding the preparation of an cell concentrate, such as, for example, an osteogenic cell concentrate, from a physiological solution, such as bone marrow aspirate, blood, or a mixture thereof. In specific embodiments, the invention provides methods and compositions utilizing two physiological solution-processing techniques, particularly in a point of care environment, wherein centrifugation is not employed.

The present invention relates to the use of a combination of: (i)a macromolecular erythrocyte sedimentation enhancer, and (ii) dimethyl sulphoxide (DMSO), dimethylglycine (DMG) and/or valine; to recover non-erythrocyte blood cells from a blood cell-containing sample and/or to prime non-erythrocyte blood cells to protect their integrity in subsequent cryopreservation step(s).

The invention features methods for separating cells from a sample (e.g., separating fetal red blood cells from maternal blood). The method begins with the introduction of a sample including cells into one or more microfluidic channels. In one embodiment, the device includes at least two processing steps. For example, a mixture of cells is introduced into a microfluidic channel that selectively allows the passage of a desired type of cell, and the population of cells enriched in the desired type is then introduced into a second microfluidic channel that allows the passage of the desired cell to produce a population of cells further enriched in the desired type. The selection of cells is based on a property of the cells in the mixture, for example, size, shape, deformability, surface characteristics (e.g., cell surface receptors or antigens and membrane permeability), or intracellular properties (e.g., expression of a particular enzyme).

The present disclosure discloses pharmaceutical compositions comprising hematopoietic stem cells (HSC) cells, NK cells, and T cells individually, having positive and negative surface markers and pharmaceutically acceptable excipients. The present disclosure further relates to the method for preparing the composition thereof. The present disclosure also provides a method of treating a subject comprising the use of any of said compositions in treating diseases selected from the group consisting of graft versus host disease, malignant disease, and non-malignant disease.

Methods and compositions for promoting donor-specific tolerance and immunocompetence to a recipient of a solid organ transplant, by implanting an allogeneic solid organ in a recipient in need of a solid organ transplant and further comprising surgical implantation of a tissue-engineered allogeneic cultured postnatal thymus tissue product in the recipient of a solid organ from a donor.
