oval cell

Phenotypically, B. kururiensis is a Gram negative bacterium with an oval cell morphology.

Research have indicated the presence of intraorgan stem cells of the liver that can proliferate in disease states, so-called oval cells.

About twenty percent of the parasitised cells are oval in shape (hence the species name) and some of the oval cells also have fimbriated edges (the so-called "comet cell").

Lobular type: Variable degrees of differentiation of uniform, round to oval cells with granular eosinophilic cells with prominent borders, alternating with coarsely multivacuolated fat cells (pale cells).

Thy 1 is also a marker of other kind of stem cells, for example: mesenchymal stem cells, hepatic stem cells ("oval cells"), keratinocyte stem cells, putative endometrial progenitor/(?)

There is also some evidence of bipotential stem cells, called hepatic oval cells or ovalocytes (not to be confused with oval red blood cells of ovalocytosis), which are thought to reside in the canals of Hering.
