Generating Skin-Derived Precursor-Like Cells From Human-Induced Pluripotent Stem Cell-Derived Skin Organoids.

Skin-derived precursor (SKPs) cells are multipotent stem cells found in the dermis that contribute to wound healing and induce hair follicle neogenesis when transplanted. The clinical application of adult human SKPs, however, is hindered by their loss of potency after in vitro expansion. To overcome this challenge, we aimed to isolate SKPs from human-induced pluripotent stem cell-derived skin organoids (SKOs), to enable mass production of these cells for therapeutics.

Development of Physiologically Relevant Skin Organoids from Human Induced Pluripotent Stem Cells.

The development of skin organs for studying developmental pathways, modeling diseases, or regenerative medicine purposes is a major endeavor in the field. Human induced pluripotent stem cells (hiPSCs) are successfully used to derive skin cells, but the field is still far from meeting the goal of creating skin containing appendages, such as hair follicles and sweat glands. Here, the goal is to generate skin organoids (SKOs) from human skin fibroblast or placental CD34+ cell-derived hiPSCs.
