Figure Lengend Snippet: Culturing human embryonic stem cells in ColTubes. (A) Phase-contrast images of H9 hESCs cultured in ColTubes at days 0, 1, 3, 5, and 7. (B) Live/Dead staining of H9 cells inside the tubes and released from the tubes on day 7. (C) Flow cytometry analysis shows that 99.6% of cells harvested on day 7 are Calcein AM-positive (live cells). (D) Flow cytometry analysis confirms that majority cells on day 7 express pluripotency markers OCT4 and Nanog.

Article Snippet: For a typical cell culture, H9 human embryonic stem cells (hESCs) (WA09, WiCell) loaded in 20 μ l ColTubes were suspended in 2 ml Essential 8 medium (Gibco) supplemented with 10 μ M Y-27632 (Sigma) in a 6-well plate and incubated at 37 °C with 5% CO2 and 21% O2.

Techniques: Cell Culture, Staining, Flow Cytometry

Figure Lengend Snippet: Differentiating H9 hESCs into Cardiomyocytes in ColTubes. (A) The cardiomyocyte production protocol. H9 hESCs are processed into ColTubes and expanded in E8 medium, followed by mesoderm induction for 1 d, cardiomyocyte differentiation from days 2–11, and metabolic enrichment from days 11–18. (B) Phase-contrast and fluorescent images of cells in ColTubes on days 0, 1, 3, 5, 7, 11, 15, and 18. Cardiomyocytes are cTnT-positive.
