False-colour SEM of pericyte capillary on muscle
Blood capillary in muscle: false-colour scanning electron micrograph (SEM) of a blood capillary (blue) coursing through striated skeletal muscle (rust red). In close physical association with this small blood vessel is a pericyte, a cell with long cytoplasmic extensions (yellow). The function of pericytes is obscure: suggestions include acting as phagocytes (scavenging cells), capable of transformation into smooth muscle cells & that they produce material for the construction of endothelium, the epithelium that lines all types of blood vessels. Magnification: x670 at 6x7cm size

Blood Capillaries Capillary Striated Striated Muscle Vessel Vessels False Coloured
EDITORS COMMENTS
This print from Science Photo Library showcases a false-colour scanning electron micrograph (SEM) of a blood capillary coursing through striated skeletal muscle. The intricate details are brought to life with the use of vibrant colors, highlighting the different components within this microscopic world. In the center of attention is a pericyte, an enigmatic cell with long cytoplasmic extensions depicted in striking yellow hues. Despite their mysterious nature, scientists have proposed various roles for pericytes. Some suggest that they may act as phagocytes, responsible for scavenging cellular debris and waste products. Others believe that these cells possess the ability to transform into smooth muscle cells when needed. The close physical association between the blood capillary and pericyte is evident in this image, emphasizing their interdependence within the complex network of vessels present throughout our bodies. Furthermore, it has been hypothesized that pericytes play a role in producing materials necessary for constructing endothelium - the epithelial lining found in all types of blood vessels. At a magnification level of x670 and printed at 6x7cm size, this photograph allows us to appreciate the intricacy and beauty hidden within our own anatomy. It serves as a reminder that even on such minuscule scales, there exists an extraordinary world waiting to be explored by those curious enough to delve into its depths.
