CD34 and pulmonary fibrosis: In contrast to the earlier result (Fig 4, S1 Table), the 6 mice that survived more than 56 days had significantly increased lung pathology scores compared to control mice with CD34+ cells (Fig 7B, p<0.01, mean±SE;13±1.4) and importantly all 6 mice showed lung fibrosis (Fig 7D) as well as liver fibrosis.
