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.

Described herein are methods for the preparation of stable semi-mature tolerogenic dendritic cells and compositions comprising such stable semi-mature tolerogenic dendritic cells. The stable semi-mature tolerogenic dendritic cells described herein and compositions thereof can be used for the establishment of immune tolerance when treating an autoimmune disease, graft rejection and/or graft-versus-host disease.

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.

Disclosed herein is a different and novel approach to cancer vaccines using a subject's own dendritic cells (DC's) and macrophages (Mphs) in combination to present cancer antigens to the immune system. Further disclosed are methods of producing monocyte-derived autologous DCs and Mphs loaded ex vivo with particular whole irradiated cancer cells which generates optimally activated immunostimulatory antigen-presenting cells (APCs) as a superior method for stimulating robust and long-lasting immunity to a particular cancer in vivo as compared with more traditional vaccination methods. Compositions, methods of use and methods for preparation of these DC's and Mphs with cancer cells are also disclosed herein.

Compositions, methods of treatment for liver disease such as liver fibrosis, compositions, and methods for the manufacture thereof, comprising a plurality of macrophages derived from human induced pluripotent stem cells (iPSCs), wherein the macrophages are polarized to a pro-inflammatory M1 phenotype and/or an anti-inflammatory M2 phenotype. Administration reduces fibrogenic gene expression and liver disease associated histological markers. The M1 macrophages express elevated CD80, TNF-? and IL-6. The M2 macrophages express elevated CD206, CCL17, and CCL22.

Disclosed are methods of preparing an isolated population of dendritic cells, isolated populations of dendritic cells prepared by the methods, and pharmaceutical compositions comprising the isolated population of dendritic cells. Also disclosed are methods of treating or preventing cancer using the isolated population of dendritic cells or pharmaceutical compositions.

The present invention discloses the preparation of placenta tissue derived CD106.sup.high CD151+Nestin+ mesenchymal stem cells (MSCs). In a first aspect, the invention relates to a particular method to prepare these cells at industrial scale and the cell population generated thereby. In a second aspect, the invention relates to a cell culture obtained by said particular method, containing placental CD106.sup.high CD151+Nestin+ MSCs expressing the vascular cell adhesion molecule 1 (VCAM-1) marker. The present application shows that said placental CD106.sup.high CD151+Nestin+ MSCs are capable of inducing angiogenesis in vitro and in vivo. The herein presented results also show that administering said placental CD106.sup.high CD151+Nestin+ MSCs to individuals suffering from an ischemic disease or from a disorder of the circulatory system results in a detectable improvement of one or more symptoms of said disease or disorder. Therefore, in a third aspect, the invention relates to placental CD 106.sup.high CD151+Nestin+ MSCs 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 disclosure discloses a kind of new NKT-like cell subpopulation, a therapeutical composition comprising the NKT-like cell subpopulation, and the medical use thereof. The disclosure also provides a preparation method of the NKT-like cell subpopulation. The disclosed NKT-like cell subpopulation has a strong antitumor effect, and can be adoptive transferred into a subject to treat the tumor in the subject after in vitro cultured and amplified.

The invention generally features compositions and methods for expanding long term hematopoietic stem cells (HSCs) in a population of cells. In particular, the invention relates to a method of expanding long term HSCs by culturing an initial population of HSCs with macrophages that promote self-renewal of long term HSCs. The expanded cell population provides a source of cells for therapeutic treatments utilizing HSC transplantation.

This disclosure relates to the combination of soluble ?-glucan and immune suppression-relieving agents that affect the tumor microenvironment. Soluble ?-glucan promotes an immunostimulatory environment, which allows enhanced effectiveness of anti-angiogenics, checkpoint inhibitors including non-tumor targeting antibodies.
