Quick answer

Adult stem cells are found in many organs, including bone marrow, skin, gut, skeletal muscle, brain and the rim of the cornea. Mesenchymal stromal cells can also be isolated from fat tissue, umbilical cord Wharton's jelly and dental pulp. The cells usually sit in a specialised microenvironment, or niche, which controls when they divide and when they produce mature cells.

Answer

Tissue locations are described by the National Academies report [1] and by reviews [2][3]. Limbal stem cells sit at the edge of the cornea [10].
