Abstract: Inhibitors of the p27 cyclin dependent kinase inhibitor protein or sequences encoding the protein modulate vertebrate cell cycle progression and increase the proportion of dividing cells to non-dividing cells in a population of treated cells. As the proportion of dividing cells increases, the cell population, e.g., hematopoietic progenitor (stem) cells, is more efficiently used for gene therapy applications.

Abstract: A novel gene, Inhibitor of MyoD Family (I-mf), is provided which encodes novel proteins, I-mfa, I-mfb and I-mfc, involved in regulation of myogenesis during vertebrate development. I-mf is highly expressed in the sclerotome of developing vertebrates and is postulated to play an important role in patterning of the somite and determination sclerotomal cell fate. A unique, C-terminal interactional domain of the I-mf protein mediates physical interactions between I-mfa and members of the MyoD family of transcriptional activators and functions to inhibit transactivation of muscle specific genes by MyoD family members, thereby repressing myogenesis. Further characterization of I-mf activity shows that I-mf associates with MyoD family member proteins and retains them in the cytoplasm by masking their nuclear localization signals.

Abstract: Immortalized human stromal cell lines sustain and expand human hematopoietic precursor cells. The precursor cells are obtained from a blood product and inoculated into a culture medium conditioned by exposure to a human stromal cell line. Preferred human stromal cell lines secrete SCF, LIF, MIP1.alpha., and IL-6, as exemplified by a human stromal cell line designated HS-1. The conditioned culture medium may be supplemented with additional growth factors, such as interleukin-3. After expansion the human hematopoietic precursor cells are harvested and returned to a patient or frozen and stored. The immortalized human stromal cell lines can also be used as feeder layers in ex vivo bone marrow cultures or in colony forming assays.

Abstract: There is disclosed a method for screening for inhibitors of cellular second messenger signaling regulated by lysophosphatidic acid acyl transferase (LPAAT) and phosphatidic acid phosphohydrolase (PAPH), which method comprises contacting target cells or appropriate subcullular elements under appropriate conditions of stimulation with a candidate drug and assessing the levels of the relevant subsets of phosphatidic acid (PA) and diacylglycerol (DAG) in the presence and absence of the candidate drug.

Abstract: This invention includes methods for increasing the efficiency of transduction of cells, including non-dividing cells, by recombinant AAV vectors. The methods utilize agents that alter certain aspects of DNA metabolism, more specifically, that affect DNA synthesis and/or affect repair, that impact on maintenance of chromosomal integrity, and/or that cause damage to the cellular DNA. Agents and vectors can now also be preselected and screened for transducing ability and/or transducing agents for their effect on DNA metabolism. These agents include tritiated nucleotides such as thymidine, gamma irradiation, UV irradiation, cis-platinum, etoposide, hydroxyurea and aphidicolin.

Abstract: A substantially pure epinectin covalently linked glycoprotein complex is disclosed having a ligand portion binding at least to the .alpha..sub.3 .beta..sub.1 integrin receptor for use in modifying cellular adhesion to a substratum. Also disclosed are specific binding partners for epinectin, as exemplified by monoclonal antibody, and .alpha..sub.3 .beta..sub.1 and .alpha..sub.6 .beta..sub.4 integrin receptor peptides for use as inhibitors, antagonists, and agonists of receptor binding to epinectin ligand.

Abstract: Methods for establishing continuous SCF dependent lympho-hematopoietic progenitor cell lines capable of differentiating into erythroid, myeloid, and B lymphocytic lineages, and GM-CSF dependent neutrophil progenitor cell lines capable of differentiating into neutrophils but not into monocytes, mast cells, or basophils, by introducing into bone marrow, fetal spleen, fetal liver, or other hematopoietic myeloid cells nucleic acid encoding a dominant negative suppressor of a retinoic acid receptor-alpha and a selectable marker, and culturing the recombinant cells in culture medium containing SCF or GM-CSF, agents allowing for selective growth of the recombinant cells, and a level of retinoic acid of less than about 10.sup.-8 M to about 10.sup.-9 M in the case of establishing neutrophilic progenitor cell lines. Addition of a retinol compound induces the latter cell line to differentiate into neutrophils.

Abstract: A therapeutic method of modulating the immune response, by administering to a patient an amount of IL-4 effective to promote peripheral blood lymphocyte adhesion to microvascular endothelial cells in lymphoid organs. The IL-4 is preferably coadministered with IL-1.beta..An improved method of screening a cell line for the production of a binding partner that binds with a cell adhesion molecule, by contacting the binding partner with IL4-activated and nonactivated microvascular endothelial cells, and selecting binding partners that bind to the IL4-activated microvascular endothelial cells but not to the nonactivated microvascular endothelial cells. The selected binding partners may thereafter be tested for the ability to block lymphocyte binding to cytokine-activated endothelial cells. The binding partners are preferably also characterized by binding to human VCAM-1 and to IL4- or TNF.alpha.-activated bone marrow stromal cells. A representative embodiment is mAb 6G10 produced by hybridoma ATTC No. HB 10519.

Abstract: The present invention provides a rapid expansion method (termed "REM"), for quickly generating large numbers of T lymphocytes, including cytolytic and helper T lymphocytes. REM involves culturing the T cells in association with a disproportionately large concentration of nondividing feeder cells, preferably .gamma.-irradiated peripheral blood mononuclear cells ("PBMC") present at an excess of at least 40-fold (relative to the number of target T cells), more preferably at an excess of at least about 200-fold. Cultures grown under REM exhibit dramatically enhanced expansion rates that can be even further elevated by the use of appropriate concentrations of an additional feeder cell, an anti-CD3 monoclonal antibody and IL-2, as described herein. Clonal expansions in the range of 500-fold to 3000-fold can be achieved within a single stimulation cycle of about 10-13 days, which is more than 100-fold more efficient than currently employed methods of culturing human T cell clones.
