Embodiments relate to novel compositions and methods for treating solid tumors. Other embodiments relate to generating T cells able to home to and treat solid tumors. In accordance with these embodiments, T-cells expressing at least one C-X-C Motif Chemokine Receptor (CXCR) and chimeric antigen receptors (CARs) able to bind to B7H3 are disclosed. In certain embodiments, the present disclosure provides for polynucleotides and vectors encoding a CAR and a CXCR together or in separate constructs, where the CAR binds to B7H3 in solid tumor cells, other tumors, or malignancies. In other embodiments, methods of making T cells expressing a CAR that binds to B7H3 and expressing one or more CXCR are provided. In some embodiments, methods of preventing, treating, or ameliorating tumors or malignancies in a subject are disclosed including administering a composition of T cells expressing at least one CXCR and CARs that bind to B7H3.

Provided is a method for producing an economical bovine serum composition containing many factors useful for cell proliferation. The method includes a step of performing an anticoagulation treatment of bovine whole blood with an anticoagulant, a step of obtaining a buffy coat and a fraction with a heavier specific gravity than that of the buffy coat from the anticoagulated whole blood, and a step of promoting and activating an interaction between the obtained leukocytes and platelets at a given temperature for not less than a given time to cause secretion or release of a humoral factor from the leukocytes and/or platelets and performing a recoagulation treatment of blood components including the humoral factor with a re-coagulating agent.

The present invention relates to an in vitro culture of haematopoietic cells, wherein the haematopoietic cells differentiate to form granulocytes characterised by the ability to kill cancer cells. The invention also relates to the granulocytes, methods for identifying the haematopoietic cells and granulocytes, compositions and kits comprising the same, as well as uses of the same for treating cancer.

The invention relates to methods for generating multipotent mammary stem cells from isolated and cultured human breast luminal cells. The method comprises the steps: 1. isolating and growing normal differentiated cells in vitro; 2. treating the differentiated cells with either a conditioned medium from active fibroblasts or cytokine. The invention also relates to multipotent mammary stem cells, cultures of the multipotent stem cells, differentiated cells, tissues, organs derived from the culture multipotent stem cells isolated by the methods disclosed and therapeutic and other uses for those cells thereof.

Provided herein are stimulated placental stem cells and methods of treating individuals having diseases or disorders of the circulatory system using stimulated placental cells. The invention also provides methods of inducing angiogenesis using such stimulated cells or populations of cells comprising such stimulated cells.

The invention relates to methods for generating multipotent mammary stem cells from isolated and cultured human breast luminal cells.

The invention relates to methods for generating multipotent mammary stem cells from isolated and cultured human breast luminal cells. The method comprises the steps: 1. isolating and growing normal differentiated cells in vitro; 2. treating the differentiated cells with either a conditioned medium from active fibroblasts or cytokine. The invention also relates to multipotent mammary stem cells, cultures of the multipotent stern cells, differentiated cells, tissues, organs derived from the culture multipotent stem cells isolated by the methods disclosed and therapeutic and other uses for those cells thereof.

The present invention is drawn, in part, to biocompatible compositions comprising a biocompatible polymer matrix and conditioned cell medium comprising i) a cell culture medium and ii) one or more agents synthesized by and secreted from one or more cells cultured in the cell culture medium, as well as therapeutic uses thereof, particularly in modulating bone and/or gum tissue growth.

A method for producing mature chondrocytes suitable for transplantation includes a cartilage culture step for culturing a cartilage using a first culture medium to give mature chondrocytes, wherein the first culture medium contains hydrocortisone and FGF-2. The cartilage is an auricular cartilage. The culturing step includes a step of culturing the cells under an environment of 2% or more and 15% or less of carbonic acid gas and 1% or more and 10% or less of oxygen gas against air.
