The present invention relates to a method for isolating and/or identifying stem cells having adipocytic, chondrocytic and pancreatic differentiation potential, wherein an antibody is used that binds to the antigen TNAP, alone or in combination with an antibody that binds to the cell surface antigen CD56. The invention also relates to stem cells isolated by the method according to the invention for treating defects or damages or diseases in bone or cartilage of a patient in need thereof.

Isolation and/or identification of stem cells having adipocytic, chondrocytic and pancreatic differentiation potential

The present invention relates to anti-FLT3 antibodies with a modified Fc region comprising the amino acid substitutions 239D and 332E to enhance antibody-dependent cell cytotoxicity (ADCC) of these antibodies. The invention further relates to pharmaceutical compositions containing these antibodies, nucleic acids encoding these antibodies as well as methods of using such antibodies.

Anti-FLT3 antibodies

Monoclonal antibodies, or fragments thereof, are used for isolating and/or identifying at least one cell population. The cell population can include any of the following types of cells: haematopoietic stem cells, neuronal stem cells, neuronal progenitor cells, mesenchymal stem cells and mesenchymal progenitor cells. The antibodies, or fragments thereof, bind to an antigen which is the same as that bound by an antibody which is produced by the hybridoma cell lines CUB1, CUB2, CUB3 and CUB4, which were deposited in the DSMZ under the numbers DSM ACC2569, DSM ACC2566 and DSM ACC2565, on 14 Aug. 2002, and DSM ACC2551, on 12 Jul. 2002.

Antibodies for identifying and/or isolating at least one cell population

The present invention relates to a monoclonal antibody or fragment thereof, which binds specifically and/or selectively to human receptors of the Frizzled (FZD) family. It further relates to a hybridoma cell that produces the antibody according to the invention. Another object of the present invention is a method for the detection and/or isolation of receptors of the FZD family or homologs or fragments thereof in a biological sample and a method for the identification and/or isolation of biological material comprising or expressing receptors of the FZD family or homologs or fragments thereof. The invention further relates to the use of the antibody according to the invention or fragments thereof for the specific and/or selective detection and/or isolation of receptors of the FZD family, a composition comprising the monoclonal antibody according to the invention or fragments thereof, and a kit comprising the monoclonal antibody according to the invention or fragments thereof.

Monoclonal antibody against frizzled receptor 4

The invention relates to monoclonal antibodies, or fragments thereof, for isolating and/or identifying at least one cell population which is selected from the group comprising haematopoietic stem cells, neuronal stem cells, neuronal progenitor cells, mesenchymal stem cells and mesenchymal progenitor cells. The antibodies, or fragments thereof, bind to an antigen which is the same as that bound by an antibody which is produced by the hybridoma cell lines CUB1, CUB2, CUB3 and CUB4, which were deposited in the DSMZ under the numbers DSM ACC2569, DSM ACC2566 and DSM ACC2565, on Aug, 14, 2002, and DSM ACC2551, on Dec. 7, 2002.

Antibodies for identifying and/or isolating at least one cell population which is selected from the group comprising haematopoietic stem cells, neuronal stem cells, neuronal precursor cells, mesenchymal stem cells and mesenchymal precursor cells

The present invention relates to mono clonal antibodies or fragments thereof for isolating and/or identifying neural progenitor cells. The antibodies or fragments thereof bind to an identical antigen as an antibody which is produced by the hybridoma cell lines W4A5, W8C3 and 57D2 deposited on Aug. 14, 2002, at the Deutsche Sammlung von Mikroorganismen und Zellkulturen (DSMZ) under the numbers DSM ACC2571, DSM ACC2570 and DSM ACC2568.
