Adipose Mesenchymal Stem Cells (AMSC) for Treatment of Ulcerative Colitis
Ulcerative colitis is a form of inflammatory bowel disease characterized by diffuse inflammation of the colonic mucosa. It affects the rectum and extends proximally along a variable length of the colon. Ulcerative colitis is a chronic condition with a relapsing remitting course. Mesenchymal stem cells (MSCs) are a subset of adult stem cells residing in many tissues, including bone marrow (BM), adipose tissue, umbilical cord blood. Recent experimental findings have shown the ability of MSCs to home to damaged tissues and to produce paracrine factors with anti-inflammatory properties, potentially resulting in reduction of inflammation and functional recovery of the damaged tissues. The purpose of our study is to evaluate safety and efficacy of the intracolonic injection by using a colonoscope of allogeneic adipose MSCs in patients with moderate active ulcerative colitis.
Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms
An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.
An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.
Searching Both is inclusive of interventional and observational studies.

This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.
Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.
Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.
Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.
Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.
