Activation1

  • Competition may block skin repair by preventing functional epidermal cells from expanding

    Where this hypothesis actsBasal keratinocytes competing with damaged neighboring cells in ageing epidermis

    What is proposedRestore competition that permits functionally competent keratinocytes to expand

    With whatNot stated in the record

    HowNot stated in the record

    Possible resultPossible epidermal renewal, followed by delayed dermal recovery and normalization across all five domains
