The Role of Stem Cells in the Therapy of Stroke

Stroke is a major challenge in neurology due to its multifactorial genesis and irreversible consequences. Processes of endogenous post-stroke neurogenesis, although insufficient, may indicate possible direction of future therapy. Multiple research considers stem-cell-based approaches in order to maximize neuroregeneration and minimize post-stroke deficits.

Aim of this study is to review current literature considering post-stroke stem-cell- based therapy and possibilities of inducing neuroregeneration after brain vascular damage.

Papers included in this article were obtained from PubMed and MEDLINE databases. The following medical subject headings (MeSH) were used: "stem cell therapy", "post-stroke neurogenesis", "stem-cells stroke", "stroke neurogenesis", "stroke stem cells", "stroke", "cell therapy", "neuroregeneration", "neurogenesis", "stem-cell human", "cell therapy in human". Ultimate inclusion was made after manual review of the obtained reference list.

Attempts of stimulating neuroregeneration after stroke found in current literature include supporting endogenous neurogenesis, different routes of exogenous stem cells supplying and extracellular vesicles used as a method of particle transport.

Although further research in this field is required, post stroke brain recovery supported by exogenous stem cells seems to be promising future therapy revolutionizing modern neurology.
