Laminin and Platelet-Derived Growth Factor-BB Promote Neuronal Differentiation of Human Urine-Derived Stem Cells

Morphology of USCs and G-banded karyotypes for USCs. A–H The USCs at passage 4 were expanded and were cultured in growth medium. USCs show the cobblestone-shaped morphology. Images are shown at ×200 magnification. I–P Chromosome analysis of USCs at passage 4. Karyotype analysis showed that USCs had a normal size, shape, and number of chromosomes. USCs did not show any chromosomal aberration
