Each stem cell can only proliferate a certain number of times due to the "Hayflick limit", and therefore uncontrolled proliferation can lead to loss of stem cell populations and premature aging. (news-medical.net)

However, the cell types that somatic stem cells produce are usually restricted to those of the organ in which they sit. (neurosciencenews.com)
