Methods, compositions and cells are provided that identify and isolate a population of adult non-embryonic progenitor cells having multilineage potential, physical diameters of about 2 m to about 8 m in size or about 4 m to about 6 m, and expressing at least one of the stem cell associated genes among Oct-4, KLF-4, Nanog, Sox-2, Rex-1, GDF-3 or Stella. Methods are also provided that identify and isolate populations, which are subsets or subpopulations of progenitor adult stem cells within the population of the adult stem cells which is a heterogeneous population, the methods including contacting the adult stem cells with a ligand specific for at least one of: CD99, tetraspan, ICAM4, full-length MUC1, and truncated MUC1 receptor, in which a presence of a surface protein on the cells that bind to the ligand identifies the population which is the subset of the differentiated progenitor adult stem cells.

The present disclosure relates to compositions, constructs and vectors for reprogramming cells into plasmacytoid dendritic cells or interferon type I-producing cells, methods and uses thereof. The present disclosure relates to the development of methods for making plasmacytoid dendritic cells or interferon type I-producing cells that promote antiviral and anti-tumoral immune responses from differentiated, multipotent or pluripotent stem cells by introducing and expressing isolated/synthetic transcription factors. More particularly, the disclosure provides methods for obtain plasmacytoid dendritic cells or interferon type I-producing cells by direct cellular reprogramming with the surprisingly use of combinations of specific transcription factors.
