International Journal of Bioprinting Skin bioprinting: Keratinocytes and stem cells

Figure 9. Size and cell distribution of the bioprinted constructs. (A) Area of biofabricated cell-laden and cell-free constructs composed of alginate (Alg)/
hyaluronic acid (HA)/gelatin (Gel) or gelatin methacryloyl (GelMA). Data represented as mean ± standard deviation (n = 3); * p ≤ 0.05. (B) HaCaTs and
adipose-derived stem cells (ADSCs) bioprinted in Alg/HA/Gel and Alg/HA/fibrin (Fib); HaCaTs are stained with DiI (pink) and ADSCs are stained with
Oregon green (yellow) before the printing process. Scale bar: 2 mm.

Figure 10. Combined metabolic activity of cells within the bioprinted constructs and at the well bottom on days 1, 7, and 14 (n = 3). Data are represented
as mean ± standard deviation; *p ≤ 0.05. Abbreviations: ADSC, adipose-derived stem cell; Alg, alginate; Gel, gelatin; GelMA, gelatin methacryloyl; HA,
hyaluronic acid.
