Core Tip

Core Tip: Bone marrow (BM) suppression is one of the most common side effects of radiotherapy and the primary cause of death following exposure to irradiation. Although adipose tissue-derived stromal cell transplantation has emerged as a new treatment for BM suppression, the therapeutic effects are not proven conclusively. Our study showed that multiple transplantations of the adipose-derived mesenchymal stromal cells (ADSCs) delayed repopulation of BM hematopoietic stem cells. The administration of an optimal amount of ADSCs can improve survival rates following whole-body irradiation.
