Of note, we recently observed that LMSCs from severe COPD patients express lower levels of hepatocyte growth factor (HGF) and fibroblast growth factor (FGF)10 [10], which both play critical roles in distal lung repair processes [17,18,19,20], compared to those obtained from non-COPD lung tissue [10]. The gene discussed is HGF; the disease is chronic obstructive pulmonary disease.
