Human umbilical cord mesenchymal stem cells exhibit the potential to differentiate into mature cells typical of several tissues, which have been confirmed in in vivo and in vitro experiments.~To investigate the effects of hUC-MSC treatment for Pneumoconiosis, 10 patients with Pneumoconiosis will be enrolled and receive 4 times of hUC-MSC transplantation.
The purpose of this study is to evaluate the safety and efficacy of human umbilical cord mesenchymal stem cell(hUC-MSC) for Pneumoconiosis.
