Brief Summary:
Interstitial lung diseases (ILD) are a group of diseases affecting the lung interstitium. The lung scarring that occurs in ILD is often irreversible with only mitigating therapy available so far. This study intends to carry out an open, single-armed, phase I/II clinical trial to investigate whether lung stem cells can regenerate damaged lung tissue. During the treatment, lung stem cells will be isolated from patients' own bronchi and expanded in vitro. After careful characterization, cultured cells will be injected directly into the lesion by fiberoptic bronchoscopy. The safety and efficacy of the treatment will be monitored by measuring the key clinical indicators.

Arm Intervention/treatment
Experimental: lung stem cells
Patients will receive 10^6 (1 million)/Kg/person cells of clinical grade lung stem cells (LSCs)injected into lung via fiberoptic bronchoscopy.
Biological: Lung stem cells

Primary Outcome Measures :
  1. Increase of diffusing capacity of the lung for carbon monoxide (DLCO) [ Time Frame: 3~48 weeks ]

Secondary Outcome Measures :
  1. Increase of total lung capacity (TLC) [ Time Frame: 3~48 weeks ]
  2. Increase in 6 minute walk distance (6MWD) [ Time Frame: 3~48 weeks ]
  3. Life quality: assessed by St. George respiratory questionnaire (SGRQ) [ Time Frame: 3~48 weeks ]
