Transmission electron micrograph showing adjacent muscle fibers from the ventricle of a mouse cardiac muscle. This image shows the organization of muscle tissue, nucleus, cell walls and blood vessels...

A 3D reconstruction of the cardiac outflow tract (OFT) region (horizontal and vertical rotation) from stage-14 wild-type embryo stained for Tinman (Tin; red) and Msp300 (green). Tin staining reveals t...

The C2C12 cell line, a mouse myoblast line, was used here to study the regulatory factors in myogenic differentiation. After cultured in differentiation medium for 3 days, these cells differentiated i...

Mouse myoblast cells were engineered to express GFP-PCNA (proliferating cell nuclear antigen) as a marker for replication factories, and also immunostained for the DNA methylase Dnmt1. DNA was localiz...

Mouse myoblast cells were transfected with GFP-PCNA (proliferating cell nuclear antigen) as a marker for replication factories, pulsed with BrdU, fixed, and immunostained with anti-BrdU. The image sh...

Transmission electron micrograph of four longitudinally cut ventricle muscle fibers of mouse cardiac tissue. Muscle fibers are multinucleate celsl composed of myofibrils that contract when stimulated...

Transmission electron micrograph of a blood vessel in the atria of a mouse cardiac tissue. This image is a close up of a red blood cell in a blood vessel.

Figure 195 from Chapter 5 (Endoplasmic Reticulum) of 'The Cell, 2nd Ed.' by Don W. Fawcett M.D. Selective staining of tubular invaginations of the sarcolemma in the tibialis anterior of the mouse. F...

Rabbit psoas skeletal muscle fibers were held at constant length and rigor induced by immersion in glycerol. The fibers were quick-frozen by contact with a liquid helium- cooled copper block in a Heu...
