Overview of stem cell sources used in animal experiments. Arrows, including number of studies, indicate the connection between different stem cell sources and LSCD animal models that they have been transplanted to. HFSCs, hair follicle-derived stem cells; MSCs, mesenchymal stem cells; SCs, stem cells; IDPDSCs, immature dental pulp stem cells; OFSCs, orbital fat-derived stem cells; UCSCs, umbilical cord stem cells.
