In March of 2013, an online early edition of the Proceedings of the National Academy of Sciences reported that newly discovered stem cells from human breast tissue are more genetically stable than the human induced pluripoint stem cells (hiPS cells) currently being developed. In addition to avoiding the issue of using embryonic stem cells, these newly discovered cells are limited in how often they can reproduce, making them less likely to form cancers. The cells were first discovered by UC San Francisco researchers in women undergoing breast reductions. They have since found the cells in tissue from more than 60 women, and further investigation is underway.
