Abstract: The invention described herein is directed to compositions and methods for inducing red blood cell (RBC) differentiation. Additionally, provided herein are methods of treating a subject in need thereof by administering the induced RBC described herein.

Abstract: The present invention provides for compositions and methods for modulating tissue growth using tissue growth modulators, which are agents that either enhance or inhibit tissue growth as desired by a particular indication by modulating the PG or Wnt signaling pathways, or employing modulators of both PG and Wnt signaling pathways for a synergistic effect or highly selective effect.

Abstract: The present invention provides for compositions and methods for modulating hematopoetic stem cell populations by using HCS modulators, which are agents that either increase HSC numbers or decrease HSC numbers as desired by a particular indication. For example, HSC modulators found to increase HSC numbers include prostaglandin E2 (PGE2) and agents that stimulate the PGE2 pathway. Conversely, HSC modulators that prevent PGE2 synthesis decrease HSC numbers. HCS modulators may be used in vitro, in vivo, or ex vivo.

Abstract: Described herein are methods, compositions and kits related to manipulating hematopoietic stem cells (HSC) and more particularly to methods, compositions and kits related to increasing the number of hematopoietic stem cells in vitro, ex vivo and/or in vivo. Also described are methods, compositions and kits related to making an expanded population of HSC and methods, compositions and kits related to using the expanded population of HSC. For example, HSC growth may be enhanced by contacting the nascent stem cells or HSC with an agent that stimulates the nitric oxide signaling pathway.
