Abstract: The present invention relates to mesenchymal stromal cells and to an advantageous method for their isolation from umbilical cord. In particular, the cells are obtainable by a method comprising isolating the stromal Wharton's Jelly or a fraction thereof from an umbilical cord and subjecting the stromal Wharton's Jelly or fraction thereof to enzymatic treatment, thereby releasing at least one cell from the stromal Wharton's Jelly or fraction thereof. Preferably, cultivation of cells occurs under conditions allowing the expansion of the cell population. The cell population according to the present invention has proliferative properties and is of industrial interest for a variety of purposes.
