Type VII collagen (Col7) is a major component of the anchoring fibrils at the dermoepidermal junction. Adipose-derived stem cells (ADSCs) are a cell population highly useful in regenerative medicine because of their ease of isolation and their potential for multilineage differentiation. Based on the observations that K14 was expressed in undifferentiated ADSCs and the expression was downregulated after differentiation into adipocytes, we speculated that ADSCs are keratinocyte stem/progenitor cells. ADSCs were co-cultured with fibroblasts on type IV collagen in a medium containing all-trans retinoic acid and bone morphogenetic protein 4. At day 14 of culture in keratinocyte serum-free medium, the cells were harvested and subjected to immunofluorescence, flow cytometry, real-time PCR, and western blotting. Approximately, 45% of ADSCs were immunostained positively for anti-human cytokeratin 10, and approximately 80% were stained positively for Col7. Flow cytometry, real-time PCR, and western blotting also confirmed that differentiated ADSCs expressed higher levels of Col7. These findings support the therapeutic potential of ADSCs, not only for wound healing, but also for the correction of Col7 deficiencies.
