SINAIS PARÁCRINOS DE CÉLULAS ALIMENTADORAS MESENQUIMAIS E REGULAÇÃO DA EXPANSÃO E DIFERENCIAÇÃO DE PROGENITORES HEPÁTICOS USANDO OS MESMOS

摘要

A method is provided for controlling the survival, proliferation, and/or differentiation of hepatic progenitors in vitro by using specific types of mesenchymal feeder cells or one of more of the paracrine signals produced by those feeders.
