  • Publication number: 20210348123
    Abstract: Described herein are cells, cell culture methods, and cell culture media compositions useful for producing and maintaining iPSC-derided cell lines that are of higher purity and maintain cell type integrity better than current iPSC-derived cell lines. Also disclosed are methods of using the described cells and media, such as therapeutic methods of use for the described cells. The described cells include iPSC-derived mesodermal precursor cells (MPC), which itself may differentiate into at least four different cell types. When cultured under appropriate conditions, the mesodermal precursor cells can be used to produce hematopoietic stem cells (HSC), mesenchymal stem cells (MSC), smooth muscle cells (SMC), or unlimited functional endothelial cells (UFEC). One characteristic that makes the described cells desirable is that they can be maintained in culture for a number of days, or passages, without changing phenotype through differentiation.

  • Publication number: 20070166290
    Abstract: A glial precursor cell population from mammalian central nervous system has been isolated. These A2B5+ E-NCAM? glial-restricted precursor (GRP) cells are capable of differentiating into oligodendrocytes, A2B5+ process-bearing astrocytes, and A2B5? fibroblast-like astrocytes, but not into neurons. GRP cells can be maintained by regeneration in culture. GRP cells differ from oligodendrocyte-type-2 astrocyte (O-2A) progenitor cells in growth factor requirements, morphology, and progeny. Methods of use of GRP cells are also disclosed.
