CD34 and dermatitis: We depleted Lin− cells of CD127+ and NK1.1+ cells to exclude any possible influence from innate like lymphoid (ILL) cells with immune suppressive function33, 34 and isolated Sca-1-positive cells from these Lin−CD127−NK1.1− cells to enrich the Sca-1+CD34−/+Lin− long term/short term HSCs35 for transplantation into dermatitis mice (Fig. S6a, Supplementary).
