Dendritic cell

False-colored SEM image of a migrating mouse dendritic cell (5.2 µm), showing membrane projections known as lamellipodia (green). Dendritic cells are sentinels of the immune system that are posted in peripheral tissues, ingest intruders and then migrate to the lymphoid organs. There, they expose some of their digested protein fragments (antigens) using their cell membrane as a showcase, report on the intruder and interact with- and instruct effector immune cells known as T-lymphocytes.

Nanostructured hydroxyapatite

Nanostructured hydroxyapatite powder with biopolymers. Microparticles formed by nanoparticles of hydroxyapatite crystals, with needle shape and stabilized with polymer surfactants, resulting in a structure similar to a blackberry. In the field of regenerative medicine, there is a great use of this biomaterial due to the similarity to the main inorganic constituent of natural bone and teeth. The synthetic hydroxyapatite has excellent biocompatibility and bioactivity to be used as a suitable bone substitute.

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”.
