An immature heart muscle cell (cardiac myocyte) photographed through a microscope. Actin filaments color-coded for Z positions are shown. #CellBiology

A crawling cell videoed through a microscope. Actin filaments (magenta) and the Arp2/3 (cyan) are shown. #CellBiology

A cell undergoing cell division videoed through a microscope. Chromosomes (red), the Golgi apparatus (green) and actin filaments (blue) are shown. I love watching the Golgi reforming in newly created daughter cells. #CellBiology
