Abstract: Embodied herein are methods of reprogramming somatic cells or tissue stem cells to a more multipotent state or even a pluripotent state, the methods do not involve gene transfer of master transcription factor genes/proteins. The methods are also useful for rapid and efficient cloning of induced pluripotent stem cells after gene transfer of master transcription factor genes/proteins.

Abstract: This invention provides methods of determining the number and percent of tissue specific stem cells (TSSCs) in a sample of cells, a population of cells or a sample of tissue. The methods rely on detecting the pattern-specific asymmetric localization of asymmetric self-renewal associated (ASRA) proteins or cell cycle specific proteins (CSSP) in cell undergoing asymmetrical self-renewal, which is a characteristic of TSSCs. The methods can be applied to any situations in which the percent of TSSC is desired such as laboratory research on adult stem cells, in drug development tests, prognostic indicator and therapeutic index, as a diagnostic and prognostic indicator and in monitoring TSSC expansion, e.g., in cell manufacturing processes.

Abstract: A homogenous sample of identical bispecific antibody determinants, each determinant being composed of two L-H half-molecules linked by disulfide bonds, each L-H half-molecule being specific for a different antigenic determinant and including at least the F(ab') portion of a monoclonal IgG antibody. The bispecific antibody determinants are useful, e.g., in the formation of multilamellar assemblies and in enzymatic assays.

Abstract: Toxicity of asbestos is reduced by treating it with non-mutagenic non-toxic hydroxamic acid iron-chelating agents.
