title: Keratinocytes form multi-cell clusters in the absence of cell division or collagen synthesis; tunicamycin interferes with cell cluster formation.
abstract: Cultivated human keratinocytes attach to substrate, spread, move, and collide forming multicell clusters in the absence of cell division and collagen synthesis. Tunicamycin profoundly retards the formation of keratinocyte clusters.
