Exploring the incredible power of VSELsTM

Our scientists are evaluating the therapeutic potential of so-called very small embryonic-like stem cells, which we refer to as “VSELs™” or “VSELTM stem cells.”

These cells were originally described in mice by researchers at the University of Louisville. Our research has identified cells in human blood and bone marrow that have many of the properties described for murine VSELsTM. This research includes evidence of multipotency and multi-lineage differentiation. These observations provide the groundwork for the development of VSELTM therapies to regenerate or repair damaged or diseased tissues in human subjects.

Preclinical animal models have demonstrated that highly enriched human VSELsTM, when injected in the vitreal or subretinal space can migrate and integrate into areas of damage and have the ability to differentiate and express markers of retinal stem cells, neuronal cells, and photoreceptors and thus, through further studies, may demonstrate VSELsTM potential to treat ocular diseases such as macular degeneration, retinitis pigmentosa, and other retinal degenerative diseases that have no effective treatment options today.

Through grant funding, together with NeoStem’s own funding, we are exploring VSELTM treatment development for chronic wounds and retinal repair.
