THE ROLE OF STEM CELLS IN THE PROCESS OF ENDOGENIC REGERATION OF CENTRAL NERVOUS SYSTEM BASED ON SELECTED VASCULAR DISEASES

Central nervous system (CNS) is seen as crucial in the organism and plays critical role in regulation and decision making processes on multisystem and behavioral level. The variety of diseases affecting CNS, and lack of effective therapy raises a question of chance of maintenance or recovery of the nervous function within the organism own forces. The presence of heterogenic population of stem (SCs) and progenitor cells in various regions of the retina and brain is well documented.

MELANOPSIN: A NEWLY DISCOVERED PHOTORECEPTOR CONTROLLING CIRCADIAN RHYTHMS

The visual system is now known to be composed of two anatomically and functionally distinct pathways, i.e. the image-forming and non-image-forming. Photoreception of the image-forming pathway begins with rods and cones, classical photoreceptors, whereas that for the non-image-forming pathway is predominantly based on intrinsically photosensitive retinal cells containing the newly discovered photo- pigment – melanopsin.
