The protruding spindle microtubules are surrounded by an extension of the nuclear envelope. elongated mitotic spindle microtubules protruding from spindle pole body during M-phase long mitotic spindle microtubules protruding from spindle pole body during vegetative growth midori mitotic spindle microtubules protruding beyond spindle pole body long mitotic spindle microtubules protruding beyond spindle pole body, with nuclear envelope protrusion long mitotic spindle microtubules protruding beyond spindle pole body, with nuclear envelope deformation nuclear envelope protrusion present during mitosis
