Fig. 4From: Senescence of bone marrow-derived mesenchymal stem cells from patients with idiopathic pulmonary fibrosisIPF B-MSC migration is impaired. Cell migration was determined by creating a wound gap and the progression of wound closure was photographed using an inverted microscope. Idiopathic pulmonary fibrosis (IPF) and age-matched (Old) B-MSCs were incubated in growth medium with or without 1% IPF serum (n = 3) for 48 hBack to article page
