Fig 5. (A-D) Confocal microscopic analysis of embryonic stem cell (ESC) markers in cells of in situ cross-sections and adherent monolayers. WJ,
PV, SA and AM were positive for SSEA-3, SSEA-4, Tra-1-60 and Tra-1-81.

Degree of differentiation
The comparative scores for the expression levels of the adipocyte, osteocyte and chondrocyte
genomic markers showed that the levels were significantly greater for cells in WJ, PV, SA, AM
and MC compared to their respective undifferentiated controls (P< 0.05) and there were no
