Prospects for the Use of Induced Pluripotent Stem Cells in Animal Conservation and Environmental Protection

Summary

Stem cells are unique cell populations able to copy themselves exactly as well as specialize into new cell types. Stem cells isolated from early stages of embryo development are pluripotent, i.e., can be differentiated into multiple different cell types. In addition, scientists have found a way of reverting specialized cells from an adult into an embryonic‐like state. These cells, that are as effective as cells isolated from early embryos, are termed induced pluripotent stem cells (iPSCs). The potency of iPSC technology is recently being employed by researchers aimed at helping wildlife and environmental conservation efforts. Ambitious attempts using iPSCs are being made to preserve endangered animals as well as reanimate extinct species, merging science fiction with reality. Other research to sustain natural resources and promote animal welfare are exploring iPSCs for laboratory grown animal products without harm to animals offering unorthodox options for creating meat, leather, and fur. There is great potential in iPSC technology and what can be achieved in consumerism, animal welfare, and environmental protection and conservation. Here, we discuss current research in the field of iPSCs and how these research groups are attempting to achieve their goals. S tem C ells T ranslational M edicine 2019;8:7–13
