Provided herein are methods for the prevention and treatment of an abnormal tissue condition in the liver (e.g., liver cancer) of a subject, based on the administration of an inhibitor of a G protein-coupled estrogen receptor 1 (GPER1).

Estrogen sensing through GPER1 regulates normal and malignant liver growth

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.

Method to enhance tissue regeneration

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 E(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.

Methods for promoting HSC engraftment

Methods for promoting HSC self-renewal
