A hybrid mammalian cell cycle model [PDF]

open access: yesEPTCS 125, 2013, pp. 68-83, 2013
Hybrid modeling provides an effective solution to cope with multiple time scales dynamics in systems biology. Among the applications of this method, one of the most important is the cell cycle regulation. The machinery of the cell cycle, leading to cell division and proliferation, combines slow growth, spatio-temporal re-organisation of the cell, and ...

Cell hybridization and cell agglutination II. enhancement of cell hybridization by polycations [PDF]

open access: yesJournal of Cell Science, 1985
ABSTRACT An efficient technique for hybridization of mammalian cells was developed by combining agglutination by pretreatment with polycations, such as polyarginine, and conventional polyethylene glycol(PEG)-mediated cell fusion. Polyarginine and subsequent PEG treatment resulted in markedly decreased viability in the treated cells, but ...
