Researchers at the Texas Center for Cancer Nanomedicine (TCCN) have created particle-based vaccines for the treatment of cancer. The particles carry molecules that stimulate immune cells and cancer antigens (proteins) that direct the immune response. This scanning electron microscope image shows dendritic cells, pseudostained green, interacting with T cells, pseudostained pink. Dendritic cells internalize particles, provoke antigens and present peptides to T cells to direct immune responses.

Under a high magnification of 8000X, this scanning electron micrograph (SEM) revealed some of the ultrastructural morphology displayed by red blood cells (RBCs) in a blood specimen of a 6 year old male patient with sickle cell anemia, which was accompanied by hereditary persistence of fetal hemoglobin (HPFH). In these individuals, the presence of the persistent fetal hemoglogin reduces the severity of the consequences of the sickle cell disease, thereby, reducing the degree of cellular deformity

Under a very high magnification of 20,000x, this scanning electron micrograph (SEM) shows a strain of Staphylococcus aureus bacteria taken from a vancomycin intermediate resistant culture (VISA). Under SEM, one can not tell the difference between bacteria that are susceptible, or multidrug resistant, but with transmission electron microscopy (TEM), VISA isolates exhibit a thickening in the cell wall that may attribute to their reduced susceptibility to vancomycin . VISA and VRSA are specific types of antimicrobial-resistant staph bacteria. While most staph bacteria are susceptible to the antimicrobial agent vancomycin some have developed resistance. VISA and VRSA cannot be successfully treated with vancomycin because these organisms are no longer susceptibile to vancomycin. However, to date, all VISA and VRSA isolates have been susceptible to other Food and Drug Administration (FDA) approved drugs.
