Overview of the characteristics of the tissue samples used for the construction of the SE. All the skin models were constructed using donor-matched keratinocytes and fibroblasts; note that each tissue donor is followed by the co-cultured monocyte donor below so that each table row represents the combination of donors used per co-culture

NA not applicable, Donor age in years (yrs), Nskin normal skin, Kscar keloid scar, N mono normal monocytes, Ks mono keloid monocytes

^aThe only SE and mono from the same donor
