| 1 | Fifteen years of preclinical and clinical experiences about biotherapy treatment of lesions induced by accidental irradiation and radiotherapy显示文摘High dose radiation exposures involving medical treatments or accidental irradiation may lead to extended damage to the irradiated tissue. Alleviation or even eradication of irradiation induced adverse events is therefore crucial. Because developments in cell therapy have brought some hope for the treatment of tissues damages induced by irradiation, the Institute for Radiation and Nuclear Safety contributed to establish the clinical guidelines for the management of accidentally irradiated victims and to provide the best supportive care to patients all over the world. In the past 15 years, we contributed to develop and test cell therapy for protection against radiation side effects in several animalmodels, and we proposed mechanisms to explain the benefit brought by this new therapeutic approach. We established the proof of concept that mesenchymal stem cells (MSCs) migrate to damaged tissues in the nonobese diabetic/severe combined immunodeficiency immunotolerant mice model and in non-human primate after radiation exposure. We showed that the intravenous injection of MSCs sustains hematopoiesis after total body irradiation, improves wound healing after radiodermatitis and protects gut function from irradiation damages. Thanks to a tight collaboration with clinicians from several French hospitals, we report successful treatments of therapeutic/accidental radiation damages in several victims with MSC infusions for hematopoiesis correction, radio-induced burns, gastrointestinal disorders and protection homeostatic functions of gut management after radio-therapy. | Alain Chapel Sabine Francois Luc Douay Marc Benderitter Jan Voswinkel | 2013 | World Journal of Stem Cells2013，5，3： | 5 |
| 2 | New insights for pelvic radiation disease treatment:Multipotent stromal cell is a promise mainstay treatment for the restoration of abdominopelvic severe chronic damages induced by radiotherapy显示文摘Radiotherapy may induce irreversible damage on healthy tissues surrounding the tumor. It has been reported that the majority of patients receiving pelvic radiation therapy show early or late tissue reactions of graded severity as radiotherapy affects not only the targeted tumor cells but also the surrounding healthy tissues. The late adverse effects of pelvic radiotherapy concern 5% to 10% of them, which could be life threatening. However, a clear medical consensus concerning the clinical management of such healthy tissue sequelae does not exist. Although no pharmacologic interventions have yet been proven to efficiently mitigate radiotherapy severe side effects, few preclinical researches show the potential of combined and sequential pharmacological treatments to prevent the onset of tissue damage. Our group has demonstrated in preclinical animal models that systemic mesenchymal stromal cell(MSC) injection is a promising approach for the medical management of gastrointestinal disorder after irradiation. We have shown that MSCs migrate to damaged tissues and restore gut functions after irradiation.We carefully studied side effects of stem cell injection for further application in patients. We have shown that clinical status of four patients suffering from severe pelvic side effects resulting from an over-dosage was improved following MSC injection in a compationnal situation. | Alain Chapel Sabine Francois Marc Benderitter Luc Douay Jan Voswinkel | 2013 | World Journal of Stem Cells2013，5，4： | 2 |

| 4 | Amifostine对环磷酰胺衍生物所致正常造血祖/干细胞毒性的保护作用显示文摘为了估价Amifostine(WR-2721)对正常造血干细胞的保护作用,我们用不同剂量的环磷酰胺衍生物(4-HC,ASTA-Z)对13例正常造血干细胞进行了体外处理,并测定其PCM-CFU-GM,5R-CFU-GM和LTO-IC的LD_(95),发现在处理前经过WR-2721孵育的13例中10例LD_(95)明显增加(P<0.05),显示了明确的保护效果,而在9例白血病祖细胞组中,这种保护效果却没有被发现。相反,经过WR-2721孵育9例白血病祖细胞对化疗的敏感性都有不同程度的增加。 | 陈虎 Luc Douay M-C Giarratana N-C Gorin | 1995 | 中国实验血液学杂志1995，3，4： | 0 |
