ABSTRACT: Opaque polyploid cells capable of forming
megamitochondria are a constant feature in
colonies of Ishikawa endometrial epithelia, accounting for approximately
5% - 10% of the cells. Opaque cells appear to communicate
with other opaque cells via membrane
extensions and with other cells in a colony by extra-cellular vesicles. Opaque
cells form first as rectangular structures, somewhat larger than surrounding
monolayer cells. The cells eventually round up, remaining in the colony for 20 or more hours before detaching. The most unusual characteristic of Ishikawa opaque cells is
their capacity to form mitonucleons, megamitochondria that surround aggregated
chromatin. This paper reviews evidence that adaptations resulting in
megamitochondria include a loss of the
capacity for oxidative phosphorylation leaving the adapted megamitochondria
reliant on metabolism such as reductive carboxylation.
