Protein kinase CK2 is a ubiquitously expressed serine/threonine kinase which is composed of two catalytic α- or α′-subunits and two non-catalytic β-subunits. CK2 has been shown to be implicated in embryogenesis, spermatogenesis, and the development of certain organs but its role in basal differentiation processes is only sparsely analyzed. 3T3-L1 cells,(More)
Investigations of active contractions in tissue cells to date have been focused on cells that exert forces via adhesion sites to substrates or to other cells. In this study we show that also suspended epithelial cells exhibit contractility, revealing that contractions can occur independently of focal adhesions. We employ the Optical Stretcher to measure(More)
