Progenitor cells are derived stem cells that have the capability to differentiate into a specific cell types, are self-duplicating within a limited scope, and have the role of epithelium cell maintenance and repair.
Populations of heart (cardiac), lung (pulmonary) and bone marrow derived blood (endothelial) [HLB] progenitor cells become activated by cytokines and growth factors following tissue damage or injury.
Progenitor cells migrate to the target tissue site and begin the process of cell specific differentiation.
