Filter by:In this study, researchers want to determine the safety of MSCs that a patient can tolerate without causing side effects. Moreover researchers will also be looking at the function of the knee over time, which may give them some insight on the usefulness of MSCs as a treatment option.
To investigate the feasibility and short term safety issues of treatment of knee osteoarthritis with intra-articular injection with the stromal vascular fraction of abdominal adipose tissue (SVF) harvested and prepared using the Lipogems System. Hereby we wish to pave the road for a high quality randomized controlled trial investigating effectiveness of treatment of knee osteoarthritis with SVF looking at patient reported outcome, function, homeostasis of the joint and cartilage regeneration.
To evaluate the role of allogeneic mesenchymal stem cells for treatment of perianal fistulizing Crohn disease. Twenty (20) Crohn's disease patients with complex or multiple perianal or rectovaginal fistulas will be included and will be scheduled to undergo peri-fistula injections after meeting all inclusion/exclusion criteria's at baseline. Following the Pilot Phase of four (4) subjects, sixteen (16) subjects are scheduled to undergo perianal injections and after meeting all inclusion/exclusion criteria's, will be evaluated at baseline.
Background: - Cancer stem cells in breast cancer have been identified as a small population of tumor cells whose self-renewal mechanism is highly deregulated. This deregulation seems to be necessary for cancer to develop. - These cells can be identified by certain surface markers that overlap with markers associated with normal embryonic stem cells. Objective: To isolate tumor stem cells using the same methods generally used to isolate human embryonic stem cells. Eligibility: - Tissue samples will be obtained from the human cooperative network. - Samples will include normal tissues from individuals who have no opportunistic diseases and from individuals with cancer. Design: Breast cancer stem cells will be isolated, grown in the laboratory and characterized.
This study is designed for the collection of stem cells from the bloodstream for use in research studies. These cells will be studied to determine if they have unique features particular to the donor that may or may not affect their use for developing new treatments. Volunteers with or without a blood disease may be eligible to donate stem cells for this study. Women who are pregnant or breastfeeding may not enroll. Donors are evaluated with a medical history and physical examination, blood tests and an ultrasound examination of the spleen. They then undergo stem cell mobilization and apheresis as follows: Donors are given injections of a hormone called G-CSF every day for 5 days to stimulate release of stem cells from the bone marrow into the bloodstream for collection. On the day of the last injection, donors undergo apheresis to obtain white cells and stem cells. For this procedure, blood is withdrawn through a catheter (plastic tube) placed in a vein and directed into a machine where the white cells and stem cells are separated from the rest of the blood by a spinning process. These cells are extracted and collected in a bag inside the machine, and the rest of the blood is returned to the donor through a second catheter in a vein in the other arm. The procedure takes 4 to 5 hours.
