Washington June 7 (IANS): Researchers have shown that cell therapy may be used in liver disease to regenerate liver cells says a study. Investigators discovered that a human embryonic stem cell can be differentiated into a previously unknown liver progenitor cell an early offspring of a stem cell and produce mature and functional liver cells reports Science Daily. ‘The discovery of the novel progenitor represents a fundamental advance in this field and potentially to the liver regeneration field using cell therapy’ said the study's senior author Valerie Gouon-Evans PharmD Ph.D. assistant professor in the Department of Developmental and Regenerative Biology Black
