Figure 1: (a) Partially dissected human UC showing umbilical arteries, vein, Wharton’s jelly, and cord lining. (b) Umbilical cord cells from mixed cord (and for individual regions) were heterogeneous in morphology when viewed in phase contrast microscopy soon after isolation. This became more uniform with time in culture. (1) P0 ~6 days. (2) P0 ~20 days. (3) P2. Scale bars represent 100 μM.
