Figure 2: Number of trials addressing an entity, disease or other condition world-wide (in 2/2014). Clinical studies involving MSC were grouped according to the entity targeted, and 4 disciplines stick out from all studies: studies targeting the central nervous stystem (48 trials), gastrointestinal (52 studies),musculo-skeletal (63 studies) and circulatory/ischemic (55 studes) problems. Most other entities are investigated by 3 or less trials world-wide, presented by the many very narrow slices.
