Cover image: Differentiation of oil-producing sebocyte cells. GLI1, a transcription factor important for hair follicle development, is shown in green, and DNA is visualized in blue. GLI1 is found in the cytoplasm in differentiated sebocytes but is localized to both cytoplasm and nucleus in undifferentiated sebocyte precursors.
