Method Scaphiopus cells were established and maintained in MEM, with 20% fetal calf serum diluted to 80% with H20. Determinations of nuclear diameter by phase-contrast microscopy, of height by electron microscopy, and of pore frequency by freeze-etching were done on cells during the exponential growth phase (48 h after plating). For determination of nuclear size the short and long axis of 50 live cells were measured and averaged separately.
