You can build stem cell lines that reproduce stem cells. You can also "go backwards" from skin stem cells to fully featured stem cells. https://www.ncbi.nlm.n

They have been reprogrammed through inducing genes and factors to be pluripotent. iPS cells are similar to embryonic stem (ES) cells in many aspects.
