NumberTitleIssue Date
7641897Feeder layer and serum independent embryonic stem cells
Undifferentiated primordial stem cells are manipulated to permit their long term growth in defined media lacking serum and feeder layer cells by shifting the apoptotic balance of the cells, through increasing the activity of Bcl-2 family anti-apoptotic proteins or d...

7618654Mammalian myeloid progenitor cell subsets
A substantially enriched mammalian hematopoietic cell subpopulation is provided, which is characterized by progenitor cell activity for myeloid lineages, but lacking the potential to differentiate into lymphoid lineages. This population is further divided into speci...

7494807Mammalian megakaryocyte progenitor cell
A substantially enriched mammalian hematopoietic cell population is provided, which is characterized as a progenitor cell committed to the megakaryocyte lineage. Methods are provided for the isolation and culture of these cells. The cell enrichment methods employ re...

6465249Use of ଲ-catenin in the expansion of stem and progenitor cells
Mammalian progenitor or stem cells are expanded in vitro by increasing the levels of ଲ-catenin in the cell. The expanded cells substantially maintain their original phenotype including the ability to give rise to multiple types of differentiated cel...
