Method for the preparation of in vitro-derived human neutrophil precursor cells
Patent Number: 5700691This patent teaches how to differentiate hematopoietic stem cells into a type of stem cell that is committed to the neutrophil lineage. These "committed" stem cells may be administered into a neutropenic patient until endogenous neutrophils rebound.

Tissue-engineered bone repair using cultured periosteal cells
Patent Number: 5700289This patent teaches that in some situations, cells from the periosteum can be grown and used as a "stem cell like" population for the treatment of bone defects.

Submucosa as a growth substrate for islet cells
Patent Number: 5695998This patent teaches that submucosa matrix proteins are useful for expanding islet cells in vitro. This technology may allow the use of pancreatic stem cells to generate large amounts of islets for treatment of patients with Type 1 diabetes.

Growth of pancreatic islet cells
Patent Number: 5681587This patent teaches how to expand islets as much as 1000 fold !! This is performed through culture of islet stem cells in laminin 5, and other substrates derived from cell lines that are provided in the patent. This patent may be useful to stem cell companies that are currently generating islets from of a variety of stem cell sources.

Method for producing a highly enriched population of hematopoietic stem cells
Patent Number: 5681559This patent teaches the extraction of hematopoietic stem cells from fetal sources. It may be that these stem cells have more potent repopulating activity as compared to stem cells from sources.

In vitro differentiation of CD34.sup.+ progenitor cells into T lymphocytes
Patent Number: 5677139This patent teaches how to generate T cells from hematopoietic stem cells in vitro. T cells may be used for immune stimulation, or in some other cases may be used for generation of T suppressor cells. If nuclear transfer can be performed in the starting population of cells, then patient-specific T cells may be generated.
