Cells derived from postpartum placenta and methods for their isolation are provided by the invention. The invention further provides cultures and compositions of the placenta-derived cells. The placenta-derived cells of the invention have a plethora of uses, including but not limited to research, diagnostic, and therapeutic applications.

A biological catalyst for the regeneration of tissues, obtainable directly from an adipose starting material, includes adipose material in liquid solution in a quantity of between 1.0 and 1.5 grams per millilitre of adipose starting material, in which a quantity of between 2 and 30 milligrams of proteins is present, said proteins comprising at least: from 0 to 60 picograms of PDGF, from 300 to 1300 picograms of VEGF, from 10 to 100 picograms of TGFb1, from 3000 to 7500 picograms of FGFb, from 400 to 4000 picograms of IL-1 RA. The biological catalyst is obtained from a method including at least the steps of collecting an adipose starting material; centrifuging the adipose material, to separate the collected material at least into an oily fraction, an aqueous fraction and a cellular fraction; removing the surface oily fraction; collecting the aqueous fraction and the cellular fraction, in which the above-mentioned proteins are found.

The present invention relates to a pharmaceutical composition for preventing or treating chronic pulmonary disease, a pharmaceutical formulation containing the same, and a method for preparing the same, the composition comprising as an active ingredient an exosome derived from thrombin-treated stem cells. The therapeutic agent is advantageous in that since the therapeutic agent is a cell-free preparation, the risk of carcinogenesis is low and there is no problem of transplant rejection reaction, and furthermore, there is no possibility of causing the occlusion of the microvascular system upon systemic administration, and since the therapeutic agent is a non-cell separating material, it is possible to develop a pharmaceutical agent as an off-the-shelf product, thereby reducing the manufacturing cost, and the therapeutic agent has an excellent therapeutic effect for chronic pulmonary disease with a low concentration of exosome by virtue of the thrombin treatment effect.

Disclosed herein are methods of treating a subject exhibiting a solid tumor that expresses Glypican-3 (GPC3). The methods typically utilize g GPC3 chimeric antigen receptor immunoresponsive cells to a subject in need thereof to effect killing of tumor cells.

The invention provides an agent for preventing or treating a condition characterised by the presence of unwanted cells, the agent comprising: (i) a targeting moiety that is capable of targeting to the unwanted cells; and (ii) a T cell antigen, wherein the T cell antigen can be released from the targeting moiety by selective cleavage of a cleavage site in the agent in the vicinity of the unwanted cells.

The present invention relates to compositions and methods variously useful in treating cancer, inhibiting graft rejection, and treating autoimmune disease. The compositions and methods include those in which macrophages are conditioned to down regulate or upregulate the expression or activity of SIRP? or its interaction with CD47.

In the present invention, it was discovered that when vascular endothelial cells are co-cultured with mesenchymal stem cells, an improvement is brought about in the niche activity of mesenchymal stem cells and the self-renewal of hematopoietic or neural stem cells and particularly that the niche activity and the self-renewal of hematopoietic or neural stem cells can easily be controlled by regulating the stimulus (cytokines, etc.) of vascular endothelial cells to the mesenchymal stem cells. Therefore, the present invention can not only improve the self-renewal of stem cells, but also easily control it as needed, and thus is expected to expand the usefulness of mesenchymal stem cell-based cell therapy.
