PtK2 Cells are a cell line derived from male rat-kangaroo (Potorous tridactylis) epithelial kidney cells[1]. This cell line is used for a variety of application in biomedical research but is particularly popular as a model for mitosis[2] .

Origin

The PtK2 cell line was established by Kristen Walen and Spencer Brown in 1962[3]. Cells from the rat kangaroo were selected as the source of a cell line because this species has only a small number of chromosomes and these chromosomes are easily visualized under a microscope. This makes these cells particularly suited to studying mitosis.

Characteristics

PtK2 cells are relatively large and when grown in a monolayer stay flat through out the cell cycle unlike many cells that round up during mitosis[4] . PtK2 cells are resistant to adenovirus 5, coxsackievirus B5, and poliovirus 2. They are susceptible to coxsackievirus A9, herpes simplex, vaccinia, and vesicular stomatitis (Ogden strain)[5] . PtK2 cells contain intermediate filaments composed of Keratin[6] .
