Cells in a basket

The iSP cells were grown on Matrigel ® by Dr. Koei Chin (OHSU). These cells present tumorigenic phenotype by expressing constitutively active form of Her2 oncogene. They were provided by Dr. William Muller (McGill University, Montreal, Quebec). The SEM image was recorded on a FEI Helios 660 Nanolab™ using BSE mode (Magnification: 8000x). Each cell in the image shows a variety of protrusions: lamellipodia and filopodia.

Trabecular Rete of Human Oculus

The trabecular rete of human oculus consists of crossing collagen fibers with cells and extracellular matrix on the surface. Also on the surface of the trabeculae we can see round granules (not bacteria) of organic origin. The use of SEM in ophthalmologic microsurgery allows to evaluate the quality of surgical technique. These studies were conducted jointly with Lyubimova T.S. from Scientific Technical Complex “Microsurgery of oculus”.
