Methods are disclosed for forming bone and/or cartilage in an avian subject. The methods include administering to the avian subject a therapeutically effective amount of a composition comprising avian mesenchymal stem cells and a hydrogel that supports the differentiation of the avian mesenchymal stem cells into cells of an osteogenic and/or condrogenic lineage. In some embodiments, methods are disclosed for repairing a bone defect and preventing infection, such as that associated bone fracture, in an avian subject. The methods include administering locally to the bone defect a composition comprising a therapeutically effective amount of avian mesenchymal stem cells and a hydrogel, such as a methacrylated gelatin hydrogel.
The disclosure provides compositions and methods for treating diseases associated with expression of CD33. The disclosure also relates to chimeric antigen receptor (CAR) specific to CD33, vectors encoding the same, and recombinant T cells comprising the CD33 CAR. The disclosure also includes methods of administering a genetically modified T cell expressing a CAR that comprises a CD33 binding domain.
Invented are non-peptide TPO mimetics. Also invented are novel processes and intermediates used in the preparation of the presently invented compounds. Also invented is a method of treating thrombocytopenia, in a mammal, including a human, in need thereof which comprises administering to such mammal an effective amount of a selected benzimidazole derivative.
A trap vector containing a loxP sequence composed of inverted repeat sequence 1, a spacer sequence and inverted repeat sequence 2 in this order, the loxP sequence being a mutant loxP wherein a part of the inverted repeat sequence 1 or 2 is mutated.
The invention relates to methods and compositions useful for altering and assessing melanocyte stem cell self-maintenance. Loss of such self-maintenance results in loss of melanocyte stem cells and loss of natural pigmentation of hair (e.g., graying hair). Methods for identifying candidate agents to inhibit melanocyte stem cell loss and to treat subjects with loss of natural hair pigment are also provided.
Antibodies that bind to polypeptides and peptides comprising the sequence of zalpha11 Ligand as shown in SEQ ID NO: 2 are described. The antibodies may bind the full length sequence of 162 amino acid residues or a fragment thereof, including a mature polypeptide of 131 amino acid residues and smaller polypeptide and peptide sequences. The antibodies may include antibodies that are polyclonal, monoclonal, murine, humanized or neutralizing. Methods for producing the antibodies are also described.
PURPOSE: A composition for induction of movement of mesenchyme stem cell, and its inducing method are provided to make acquisition of the mesenchyme stem cell, thereby facilitating the picking. CONSTITUTION: A composition for induction of movement of mesenchyme stem cell comprises a colony stimulating factor (CSF) as an active ingredient. The colony stimulating factor comprises: GM-CSF (granulocyte macrophage-colony stimulating growth factor) and one or more than one selected from a group comprising G-CSF (granulocyte-colony stimulating growth factor). The mesenchyme stem cell exists in the bone marrow. The induction of movement method to the peripheral blood of the mesenchyme stem cell comprises the following steps. A step of multiplying the mesenchyme stem cell it processes the colony stimulating factor. The above-mentioned proliferated mesenchyme stem cell the step of moving to peripheral blood is included.
Previous methods for culturing human embryonic stem cells have required either fibroblast feeder cells or a medium which has been exposed to fibroblast feeder cells in order to maintain the stem cells in an undifferentiated state. It has now been found that if high levels of fibroblast growth factor are used in a medium with gamma amino butyric acid, pipecholic acid, lithium and lipids, the stem cells will remain undifferentiated indefinitely through multiple passages, even without feeder cells or conditioned medium. A humanized matrix of human proteins can be used as a basement matrix to culture the cells. New lines of human embryonic stem cells made using these culture conditions, the medium and the matrix, will never have been exposed to animal cells, animal products, feeder cells or conditioned medium.
