Stem Cell Therapy

Human umbilical cord blood mesenchymal stem cells can inhibit the proliferation and apoptosis of acute leukemia cells and increase the number of G0/G1 phase cells in leukemic cells. The AMD3100 can decrease the expression of surface CXCR4 protein in leukemia cells, G-CSF can decrease expression of total CXCR4 protein as well as membrane CXCR4 protein. Both of them can block the CXCL12/CXCR4 signal axis, weakening the relationship between leukemia cells and microenvironment. And on the basic of HUCMSC influenced leukemia cells’ growth and proliferation, the cell viability will be weakened, its apoptosis will be promoted, and the percentage of G0/G1 phase cells in leukemia cells will be decreased.

A 71 year-old female patient complained of an abdominal incisional hernia, complicated by enterocutaneous fistula, four-months following laparostomy. Contrast enhanced computed tomography showed an incisional hernia defect of 15.5×20cm, with a subcutaneous abscess and an intestinal loop adherent to the anterior abdominal wall, with a concomitant enterocutaneous fistula. Surgery involved abdominal wall standardized technique closure, with in addition platelet-rich plasma and bone marrow-derived mesenchymal stromal cells implanted on a biological mesh. Two years follow up showed no recurrences of incisional hernia. DISCUSSION: Coating surgical meshes with patient’s own cells may improve biocompatibility, by reducing inflammation and adhesion formation. Moreover, platelet-rich plasma is a good source of growth factors for wound healing, as well as a good medium for bone marrow multinucleate cells introduction into fascial repair.


Intraarticular injection of autologous PRP in combination with transplantation of autologous ADSCs by local adherent technique enhances the quality of cartilage defect repair with better results in comparison with microfracture surgery in a rabbit model.
