In this study researchers from Canada attempted to transplant neuronal stem cells that have been modified to produce large amounts of VEGF. Armed with their new VEGF weaponry the cells were transplanted into SOD1 MND mice.

Stem cells are a normal part of all tissues in the body. They are characterised by their ability to renew themselves and to convert into a range of specialized cell types able to perform specific functions. There are many types of stem cells in the adult body. Each of these are limited to the types of cells that they can create.

Embryonic stem cells are shaping up to be a promising tool for treating a range of diseases from heart disease to MND. With this in mind a research group headed by Dr Ivan Velasko implanted embryonic stem cells that had been converted into motor neurones into rat spinal chords.
