FIG. 2.

In vitro iPSC viability in fibrinogen. (A) iPSCs were kept in culture for 72 h in fibrinogen, fibrin, and medium. Living cells are marked in green, whereas red spots show dead cell colonies. The area of fibrinogen-cultured cells showed good cell survival (B) with small dead areas (C). (D) The cell proliferation assay also showed strong proliferation rates in the fibrinogen group. Differences between both groups were not considered significant. Color images available online at www.liebertpub.com/tea
