Morphology of mesenchymal stem cells at different passages. Phase contrast images (20 ×) of human umbilical cord-derived mesenchymal stem cells show fibroblast-like morphology at passage 0 (P0) at day 10 and day 12 of culture. Similarly, cells at passage 1 (P1) show fibroblast-like morphology with extensions at day 10 and day 12 following subculture. A: P0 at day 10; B: P0 at day 12; C: P1 at day 10; D: P1 at day 12. Confluent cells are seen in B and D.
