Stem cell dying, SEM
Stem cell dying. Coloured scanning electron micrograph (SEM) of a stem cell undergoing apoptosis, or programmed cell death. Apoptosis occurs when a cell becomes old or damaged. Blebs (vesicles) called apoptotic bodies form on its surface, which prevent toxic or immunogenic substances from leaking when it is phagocytosed (engulfed and digested) by specialist cells. Magnification: x4000 when printed 10 centimetres wide

EDITORS COMMENTS
This print from Science Photo Library captures the intricate process of stem cell death. In this coloured scanning electron micrograph (SEM), we witness a stem cell undergoing apoptosis, also known as programmed cell death. Apoptosis occurs when a cell becomes aged or damaged beyond repair. The image showcases the formation of blebs, small vesicles that appear on the surface of the dying stem cell. These apoptotic bodies serve a crucial purpose by preventing any toxic or immunogenic substances from leaking out when they are engulfed and digested by specialist cells through phagocytosis. At a magnification of x4000 when printed 10 centimetres wide, every detail is brought to life in stunning clarity. The vibrant colours highlight the biological complexity and genetic nature of this cellular event. This SEM photograph not only provides an awe-inspiring visual experience but also offers valuable insights into cytology, connective tissue, and stem cells' multipotentiality. It serves as a reminder that even at the microscopic level, life follows its natural course with processes like apoptosis playing vital roles in maintaining overall health and balance within our bodies. Science Photo Library continues to amaze us with their exceptional scientific imagery, allowing us to delve deeper into the wonders of biology and appreciate the beauty hidden within our own anatomy.
