PROGENITOR CELL POPULATIONS, EXPANSION THEREOF, AND GROWTH OF NON-HEMATOPOIETIC CELL TYPES AND TISSUES THEREFROM

摘要

Described is a method of expanding human progenitor cells by suspension culturing under non-static conditions. The culturing method provides a three - dimensional space for the rapid expansion of desirable progenitors. By this method, a new compartment of multipotential progenitor cells has been identified, which give rise under differentiation conditions to progeny including osteoblasts, chondrocytes, myoblasts, adipocytes, and other non- hematopoietic cell types. Their use in cell and tissue-based engineering is described.
