Figure 3

Ultrastructural identification of putative progenitor cells in primary cultures. HMEC and tumour primary cultures analyzed by TEM were observed to grow as multi-layers, with basally-located cells having plump morphologies (a, arrow) compared to the attenuated morphologies of apically-located cells. Filament-rich cells (b, arrows) were layered with glycogen-rich cells (b, arrowhead). A schematic representation of cellular organization is shown in (c).
