Mammalian cells in primary culture experience Heyflick limit after 50-60 cell generation time. However, in a rare situat
Mechanistically, cellular compartmentalization and cell cycle involves SNARE-mediated trafficking, Hayflick limit, P53 and cyclin regulation control proliferation. This validates P53 because it aligns with membrane trafficking and cell cycle control, a pattern repeatedly demonstrated in cell biology research.
Ref: Alberts et al., Molecular Biology of the Cell, 6th Edition, Chapter 10, Membrane Structure and Transport, discusses SNARE proteins, vesicle trafficking, ER, Golgi, endosome membranes and selective transport providing compartmentalization foundation.
