Autologous bone marrow stem cell transplantation for the treatment of ulcerative colitis complicated

Hang Xiang,Xiaomei Zhang,Chao Yang,Wenhuan Xu,Xin Ge,Rong Zhang,Ya Qiu,Wanjun Sun,Fan Li,Tianyuan Xiang,Haixu Chen,Zheng Wang,Qiang Zeng

Frontiers of Medicine 2016, Volume 10, Issue 4, Pages 522-526 doi: 10.1007/s11684-016-0485-4

Abstract:

Ulcerative colitis (UC) is a chronic inflammatory bowel disease with continuous or recurrent symptoms. A 42-year-old male patient with intermittent diarrhea accompanied by bloody mucopurulent stools was admitted to our hospital. The diagnosis of UC was confirmed by a combination of laboratory examination, colonoscopy, and histological assay. The patient developed herpes zoster in the hospital, which challenged traditional treatments. Therefore, we performed an autologous bone marrow cells to modulate the immune system with his permission. Autologous bone marrow mononuclear cells were collected and injected locally into the bowel mucosa, and subsequently injected systemically through a peripheral vein. After the patient underwent auto bone marrow mononuclear cells transplantations twice, the patient’s symptoms were alleviated. Furthermore, he recovered from hematochezia, and his hypersensitive C reactive protein decreased. Colonoscopy results showed reduced lesions and decreased areas with bleeding and edema in the sigmoid colon and rectum. No recurrence occurred in the subsequent two years, but long-time monitoring is still necessary for the prophylaxis of colorectal cancer.

Stem cell niches and endogenous electric fields in tissue repair

Li LI, Jianxin JIANG

Frontiers of Medicine 2011, Volume 5, Issue 1, Pages 40-44 doi: 10.1007/s11684-011-0108-z

Abstract:

Adult stem cells are responsible for homeostasis and repair of many tissues.Endogenous adult stem cells reside in certain regions of organs, known as the stem cell niche, whichMany regulatory factors are involved in the stem cell-based repair process, including stem cell nichesHere we briefly review the role of stem cell niches and endogenous electric fields in tissue repair,and hypothesize that endogenous electric fields become part of stem cell niche in the wound site.
