Figure 1From: Identification of p63+ keratinocyte progenitor cells in circulation and their matrix-directed differentiation to epithelial cellsRepresentative phase-contrast micrographs of cells on fibrinogen composite (FC) matrix. (A) Cells on the day of seeding; (B) on day 4 of seeding; (C) on day 8; (D) on day 12; (E, F), on day 15. A through E are at low magnification (scale bar, 200 μm), and F is at higher magnification (scale bar, 50 μm).Back to article page
