MSC-derived cytokines repair radiation-induced intra-villi microvascular injury.

Microvascular injury initiates the pathogenesis of radiation enteropathy. As previously demonstrated, the secretome from mesenchymal stem cells contains various angiogenic cytokines that exhibited therapeutic potential for ischemic lesions. As such, the present study aimed to investigate whether cytokines derived from mesenchymal stem cells can repair endothelial injuries from irradiated intestine.

The anti-fibrotic effects of mesenchymal stem cells on irradiated lungs via stimulating endogenous secretion of HGF and PGE2.

Radiation-induced pulmonary fibrosis is a common disease and has a poor prognosis owing to the progressive breakdown of gas exchange regions in the lung. Recently, a novel strategy of administering mesenchymal stem cells for pulmonary fibrosis has achieved high therapeutic efficacy. In the present study, we attempted to use human adipose tissue-derived mesenchymal stem cells to prevent disease in Sprague-Dawley rats that received semi-thoracic irradiation (15 Gy).

[A brief report on effect of rhG-CSF in treating leukopenia after radio-and chemo-therapy of patients with breast cancer].

The study was to observe the effect of rhG-CSF (lishengsu) in treating leukopenia caused by radiotherapy and chemotherapy in patients with breast cancer. 100 cases of breast cancer received modified radical mastectomy were randomized into two groups with the same treatment of one cycle chemotherapy using the protocol of CAF at two weeks after the operations and then radiotherapy. The patients in treated group received rhG-CSF 75 micro g per day s.
