Doing so will ensure that sustainable access to adequate quantities of safe and useable water will serve as a foundation for water security.
The isolation of tissue-specific stem cells for expansion in vitro and transplantation back into the patient in an allogeneic manner is an ideal strategy, from the viewpoint of industry-based, sustainable supply of large quantities of affordable, quality-controlled cells.
