This patent covers a mesenchymal-like stem cell obtained by first flushing a placenta so that cord blood is substantially cleared, and subsequently perfusing the placenta to collect cells that are CD34 negative and have stem cell properties.

The cell type covered appears to be: positive for one or more of the following markers: SH2, SH3, SH4, CD10, CD29, CD44, CD54, CD90, and OCT-4, AND negative for one or more of the following markers: CD34, CD45, SSEA3 and SSEA4.
