On a cellular level, increased staining of the hematopoietic stem cell marker c-KIT (Bakry et al., 2014) and heat shock protein 70 (Lee et al., 2013) has been observed in both keloids and their surrounding normal skin, while keratinocytes and fibroblasts from the surrounding normal skin shared the abnormal expression of many of the same genes in keloid-derived keratinocytes and fibroblasts (Hahn et al., 2013). Here, KIT is linked to keloid.
